6Testpmd Runtime Functions
7=========================
8
9Where the testpmd application is started in interactive mode, (``-i|--interactive``),
10it displays a prompt that can be used to start and stop forwarding,
11configure the application, display statistics (including the extended NIC
12statistics aka xstats) , set the Flow Director and other tasks::
13
14   testpmd>
15
16The testpmd prompt has some, limited, readline support.
17Common bash command-line functions such as ``Ctrl+a`` and ``Ctrl+e`` to go to the start and end of the prompt line are supported
18as well as access to the command history via the up-arrow.
19
20There is also support for tab completion.
21If you type a partial command and hit ``<TAB>`` you get a list of the available completions:
22
23.. code-block:: console
24
25   testpmd> show port <TAB>
26
27       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
28       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
29       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
30       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
31       ...
32
33
34.. note::
35
36   Some examples in this document are too long to fit on one line are shown wrapped at `"\\"` for display purposes::
37
38      testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
39               (pause_time) (send_xon) (port_id)
40
41In the real ``testpmd>`` prompt these commands should be on a single line.
42
43Help Functions
44--------------
45
46The testpmd has on-line help for the functions that are available at runtime.
47These are divided into sections and can be accessed using help, help section or help all:
48
49.. code-block:: console
50
51   testpmd> help
52
53       help control    : Start and stop forwarding.
54       help display    : Displaying port, stats and config information.
55       help config     : Configuration information.
56       help ports      : Configuring ports.
57       help registers  : Reading and setting port registers.
58       help filters    : Filters configuration help.
59       help all        : All of the above sections.

62Command File Functions
63----------------------
64
65To facilitate loading large number of commands or to avoid cutting and pasting where not
66practical or possible testpmd supports alternative methods for executing commands.
67
68* If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
69  will execute all CLI commands contained within the file immediately before
70  starting packet forwarding or entering interactive mode.
71
72.. code-block:: console
73
74   ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

110
111In all cases output from any included command will be displayed as standard output.
112Execution will continue until the end of the file is reached regardless of
113whether any errors occur.  The end user must examine the output to determine if
114any failures occurred.

302
303   io packet forwarding - CRC stripping disabled - packets/burst=16
304   nb forwarding cores=2 - nb forwarding ports=1
305   RX queues=1 - RX desc=128 - RX free threshold=0
306   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
307   TX queues=1 - TX desc=512 - TX free threshold=0
308   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
309   TX RS bit threshold=0 - TXQ flags=0x0
310
311set fwd
312~~~~~~~
313
314Set the packet forwarding mode::
315
316   testpmd> set fwd (io|mac|macswap|flowgen| \
317                     rxonly|txonly|csum|icmpecho|noisy|5tswap) (""|retry)
318
319``retry`` can be specified for forwarding engines except ``rx_only``.
320
321The available information categories are:
322
323* ``io``: Forwards packets "as-is" in I/O mode.
324  This is the fastest possible forwarding operation as it does not access packets data.
325  This is the default mode.
326
327* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
328  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
329  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
330  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
331
332* ``macswap``: MAC swap forwarding mode.
333  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
334
335* ``flowgen``: Multi-flow generation mode.
336  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
337
338* ``rxonly``: Receives packets but doesn't transmit them.
339
340* ``txonly``: Generates and transmits packets without receiving any.
341
342* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
343
344* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
345
346* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
347
348* ``noisy``: Noisy neighbor simulation.
349  Simulate more realistic behavior of a guest machine engaged in receiving
350  and sending packets performing Virtual Network Function (VNF).
351
352* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
353
354  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
355
356  L3 swaps the source address and destination address of IP (v4 and v6).
357
358  L4 swaps the source port and destination port of transport layer (TCP and UDP).
359
360Example::
361
362   testpmd> set fwd rxonly
363
364   Set rxonly packet forwarding mode
365
366
367show fwd
368~~~~~~~~
369
370When running, forwarding engines maintain statistics from the time they have been started.

639Configuration Functions
640-----------------------
641
642The testpmd application can be configured from the runtime as well as from the command-line.
643
644This section details the available configuration functions that are available.
645
646.. note::
647
648   Configuration changes only become active when forwarding is started/restarted.
649
650set default
651~~~~~~~~~~~
652
653Reset forwarding to the default configuration::
654
655   testpmd> set default
656
657set verbose
658~~~~~~~~~~~
659
660Set the debug verbosity level::
661
662   testpmd> set verbose (level)
663
664Available levels are as following:
665
666* ``0`` silent except for error.
667* ``1`` fully verbose except for Tx packets.
668* ``2`` fully verbose except for Rx packets.
669* ``> 2`` fully verbose.
670
671set log
672~~~~~~~
673
674Set the log level for a log type::
675
676	testpmd> set log global|(type) (level)
677
678Where:
679
680* ``type`` is the log name.
681
682* ``level`` is the log level.
683
684For example, to change the global log level::
685
686	testpmd> set log global (level)
687
688Regexes can also be used for type. To change log level of user1, user2 and user3::
689
690	testpmd> set log user[1-3] (level)
691
692set nbport
693~~~~~~~~~~
694
695Set the number of ports used by the application:
696
697set nbport (num)
698
699This is equivalent to the ``--nb-ports`` command-line option.
700
701set nbcore
702~~~~~~~~~~
703
704Set the number of cores used by the application::
705
706   testpmd> set nbcore (num)
707
708This is equivalent to the ``--nb-cores`` command-line option.
709
710.. note::
711
712   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
713
714set coremask
715~~~~~~~~~~~~
716
717Set the forwarding cores hexadecimal mask::
718
719   testpmd> set coremask (mask)
720
721This is equivalent to the ``--coremask`` command-line option.
722
723.. note::
724
725   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
726
727set portmask
728~~~~~~~~~~~~
729
730Set the forwarding ports hexadecimal mask::
731
732   testpmd> set portmask (mask)
733
734This is equivalent to the ``--portmask`` command-line option.
735
736set record-core-cycles
737~~~~~~~~~~~~~~~~~~~~~~
738
739Set the recording of CPU cycles::
740
741   testpmd> set record-core-cycles (on|off)
742
743Where:
744
745* ``on`` enables measurement of CPU cycles per packet.
746
747* ``off`` disables measurement of CPU cycles per packet.
748
749This is equivalent to the ``--record-core-cycles command-line`` option.
750
751set record-burst-stats
752~~~~~~~~~~~~~~~~~~~~~~
753
754Set the displaying of RX and TX bursts::
755
756   testpmd> set record-burst-stats (on|off)
757
758Where:
759
760* ``on`` enables display of RX and TX bursts.
761
762* ``off`` disables display of RX and TX bursts.
763
764This is equivalent to the ``--record-burst-stats command-line`` option.
765
766set burst
767~~~~~~~~~
768
769Set number of packets per burst::
770
771   testpmd> set burst (num)
772
773This is equivalent to the ``--burst command-line`` option.
774
775When retry is enabled, the transmit delay time and number of retries can also be set::
776
777   testpmd> set burst tx delay (microseconds) retry (num)
778
779set rxoffs
780~~~~~~~~~~
781
782Set the offsets of segments relating to the data buffer beginning on receiving
783if split feature is engaged. Affects only the queues configured with split
784offloads (currently BUFFER_SPLIT is supported only).
785
786   testpmd> set rxoffs (x[,y]*)
787
788Where x[,y]* represents a CSV list of values, without white space. If the list
789of offsets is shorter than the list of segments the zero offsets will be used
790for the remaining segments.
791
792set rxpkts
793~~~~~~~~~~
794
795Set the length of segments to scatter packets on receiving if split
796feature is engaged. Affects only the queues configured with split offloads
797(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
798pools can be specified with --mbuf-size command line parameter and the mbufs
799to receive will be allocated sequentially from these extra memory pools (the
800mbuf for the first segment is allocated from the first pool, the second one
801from the second pool, and so on, if segment number is greater then pool's the
802mbuf for remaining segments will be allocated from the last valid pool).
803
804   testpmd> set rxpkts (x[,y]*)
805
806Where x[,y]* represents a CSV list of values, without white space. Zero value
807means to use the corresponding memory pool data buffer size.
808
809set txpkts
810~~~~~~~~~~
811
812Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
813
814   testpmd> set txpkts (x[,y]*)
815
816Where x[,y]* represents a CSV list of values, without white space.
817
818set txtimes
819~~~~~~~~~~~
820
821Configure the timing burst pattern for Tx only mode. This command enables
822the packet send scheduling on dynamic timestamp mbuf field and configures
823timing pattern in Tx only mode. In this mode, if scheduling is enabled
824application provides timestamps in the packets being sent. It is possible
825to configure delay (in unspecified device clock units) between bursts
826and between the packets within the burst::
827
828   testpmd> set txtimes (inter),(intra)
829
830where:
831
832* ``inter``  is the delay between the bursts in the device clock units.
833  If ``intra`` is zero, this is the time between the beginnings of the
834  first packets in the neighbour bursts, if ``intra`` is not zero,
835  ``inter`` specifies the time between the beginning of the first packet
836  of the current burst and the beginning of the last packet of the
837  previous burst. If ``inter`` parameter is zero the send scheduling
838  on timestamps is disabled (default).
839
840* ``intra`` is the delay between the packets within the burst specified
841  in the device clock units. The number of packets in the burst is defined
842  by regular burst setting. If ``intra`` parameter is zero no timestamps
843  provided in the packets excepting the first one in the burst.
844
845As the result the bursts of packet will be transmitted with specific
846delays between the packets within the burst and specific delay between
847the bursts. The rte_eth_read_clock() must be supported by the device(s)
848and is supposed to be engaged to get the current device clock value
849and provide the reference for the timestamps. If there is no supported
850rte_eth_read_clock() there will be no send scheduling provided on the port.
851
852set txsplit
853~~~~~~~~~~~
854
855Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
856
857   testpmd> set txsplit (off|on|rand)
858
859Where:
860
861* ``off`` disable packet copy & split for CSUM mode.
862
863* ``on`` split outgoing packet into multiple segments. Size of each segment
864  and number of segments per packet is determined by ``set txpkts`` command
865  (see above).
866
867* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
868
869set corelist
870~~~~~~~~~~~~
871
872Set the list of forwarding cores::
873
874   testpmd> set corelist (x[,y]*)
875
876For example, to change the forwarding cores:
877
878.. code-block:: console
879
880   testpmd> set corelist 3,1
881   testpmd> show config fwd
882
883   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
884   Logical Core 3 (socket 0) forwards packets on 1 streams:
885   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
886   Logical Core 1 (socket 0) forwards packets on 1 streams:
887   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
888
889.. note::

891   The cores are used in the same order as specified on the command line.
892
893set portlist
894~~~~~~~~~~~~
895
896Set the list of forwarding ports::
897
898   testpmd> set portlist (x[,y]*)

903
904   testpmd> set portlist 0,2,1,3
905   testpmd> show config fwd
906
907   io packet forwarding - ports=4 - cores=1 - streams=4
908   Logical Core 3 (socket 0) forwards packets on 4 streams:
909   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
910   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
911   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03

1135  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1136  supported). See also the ``csum parse-tunnel`` command.
1137
1138* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1139  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1140  supported). See also the ``csum parse-tunnel`` command.
1141
1142.. note::
1143
1144   Check the NIC Datasheet for hardware limits.
1145

1169   testpmd> set port (port_id) queue-region flush (on|off)
1170
1171where:
1172
1173* ``on``: is just an enable function which server for other configuration,
1174  it is for all configuration about queue region from up layer,
1175  at first will only keep in DPDK software stored in driver,
1176  only after "flush on", it commit all configuration to HW.
1177
1178* ``"off``: is just clean all configuration about queue region just now,
1179  and restore all to DPDK i40e driver default config when start up.
1180
1181Show all queue region related configuration info on a port::
1182
1183   testpmd> show port (port_id) queue-region
1184
1185.. note::
1186
1187  Queue region only support on PF by now, so these command is
1188  only for configuration of queue region on PF port.
1189
1190csum parse-tunnel
1191~~~~~~~~~~~~~~~~~
1192
1193Define how tunneled packets should be handled by the csum forward
1194engine::
1195
1196   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1197
1198If enabled, the csum forward engine will try to recognize supported
1199tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1200
1201If disabled, treat tunnel packets as non-tunneled packets (a inner
1202header is handled as a packet payload).
1203
1204.. note::
1205
1206   The port argument is the TX port like in the ``csum set`` command.
1207
1208Example:
1209
1210Consider a packet in packet like the following::
1211
1212   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1213
1214* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1215  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1216  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1217
1218* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1219   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1260set port - gro
1261~~~~~~~~~~~~~~
1262
1263Enable or disable GRO in ``csum`` forwarding engine::
1264
1265   testpmd> set port <port_id> gro on|off
1266
1267If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1268packets received from the given port.
1269
1270If disabled, packets received from the given port won't be performed
1271GRO. By default, GRO is disabled for all ports.
1272
1273.. note::
1274
1275   When enable GRO for a port, TCP/IPv4 packets received from the port
1276   will be performed GRO. After GRO, all merged packets have bad
1277   checksums, since the GRO library doesn't re-calculate checksums for
1278   the merged packets. Therefore, if users want the merged packets to
1279   have correct checksums, please select HW IP checksum calculation and
1280   HW TCP checksum calculation for the port which the merged packets are
1281   transmitted to.
1282
1283show port - gro
1284~~~~~~~~~~~~~~~
1285
1286Display GRO configuration for a given port::
1287
1288   testpmd> show port <port_id> gro
1289
1290set gro flush
1291~~~~~~~~~~~~~
1292
1293Set the cycle to flush the GROed packets from reassembly tables::
1294
1295   testpmd> set gro flush <cycles>
1296
1297When enable GRO, the csum forwarding engine performs GRO on received
1298packets, and the GROed packets are stored in reassembly tables. Users
1299can use this command to determine when the GROed packets are flushed
1300from the reassembly tables.
1301
1302The ``cycles`` is measured in GRO operation times. The csum forwarding
1303engine flushes the GROed packets from the tables every ``cycles`` GRO
1304operations.
1305
1306By default, the value of ``cycles`` is 1, which means flush GROed packets
1307from the reassembly tables as soon as one GRO operation finishes. The value
1308of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1309
1310Please note that the large value of ``cycles`` may cause the poor TCP/IP
1311stack performance. Because the GROed packets are delayed to arrive the
1312stack, thus causing more duplicated ACKs and TCP retransmissions.
1313
1314set port - gso
1315~~~~~~~~~~~~~~
1316
1317Toggle per-port GSO support in ``csum`` forwarding engine::
1318
1319   testpmd> set port <port_id> gso on|off
1320
1321If enabled, the csum forwarding engine will perform GSO on supported IPv4
1322packets, transmitted on the given port.
1323
1324If disabled, packets transmitted on the given port will not undergo GSO.
1325By default, GSO is disabled for all ports.
1326
1327.. note::
1328
1329   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1330   port undergo GSO. Afterwards, the segmented packets are represented by
1331   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1332   of checksums for GSO'd segments in SW. As a result, if users want correct
1333   checksums in GSO segments, they should enable HW checksum calculation for
1334   GSO-enabled ports.
1335
1336   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1337   by setting the following options in the csum forwarding engine:
1338
1339   testpmd> csum set outer_ip hw <port_id>
1340
1341   testpmd> csum set ip hw <port_id>
1342
1343   testpmd> csum set tcp hw <port_id>
1344
1345   UDP GSO is the same as IP fragmentation, which treats the UDP header
1346   as the payload and does not modify it during segmentation. That is,
1347   after UDP GSO, only the first output fragment has the original UDP
1348   header. Therefore, users need to enable HW IP checksum calculation
1349   and SW UDP checksum calculation for GSO-enabled ports, if they want
1350   correct checksums for UDP/IPv4 packets.
1351
1352set gso segsz

1937rte_flow_action_raw_encap::
1938
1939 set raw_encap {index} {item} [/ {item} [...]] / end_set
1940
1941There are multiple global buffers for ``raw_encap``, this command will set one
1942internal buffer index by ``{index}``.
1943If there is no ``{index}`` specified::
1944
1945 set raw_encap {item} [/ {item} [...]] / end_set
1946
1947the default index ``0`` is used.

2005Port Functions
2006--------------
2007
2008The following sections show functions for configuring ports.
2009
2010.. note::
2011
2012   Port configuration changes only become active when forwarding is started/restarted.
2013
2014port attach
2015~~~~~~~~~~~
2016
2017Attach a port specified by pci address or virtual device args::
2018
2019   testpmd> port attach (identifier)
2020
2021To attach a new pci device, the device should be recognized by kernel first.
2022Then it should be moved under DPDK management.
2023Finally the port can be attached to testpmd.
2024
2025For example, to move a pci device using ixgbe under DPDK management:
2026
2027.. code-block:: console
2028
2029   # Check the status of the available devices.
2030   ./usertools/dpdk-devbind.py --status
2031
2032   Network devices using DPDK-compatible driver
2033   ============================================
2034   <none>
2035
2036   Network devices using kernel driver
2037   ===================================
2038   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2039
2040
2041   # Bind the device to igb_uio.
2042   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2043
2044
2045   # Recheck the status of the devices.
2046   ./usertools/dpdk-devbind.py --status
2047   Network devices using DPDK-compatible driver
2048   ============================================
2049   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2050
2051To attach a port created by virtual device, above steps are not needed.
2052
2053For example, to attach a port whose pci address is 0000:0a:00.0.
2054
2055.. code-block:: console
2056
2057   testpmd> port attach 0000:0a:00.0
2058   Attaching a new port...
2059   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2060   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
2061   EAL:   PCI memory mapped at 0x7f83bfa00000
2062   EAL:   PCI memory mapped at 0x7f83bfa80000
2063   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2064   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2065   Port 0 is attached. Now total ports is 1
2066   Done
2067
2068For example, to attach a port created by pcap PMD.
2069
2070.. code-block:: console
2071
2072   testpmd> port attach net_pcap0
2073   Attaching a new port...
2074   PMD: Initializing pmd_pcap for net_pcap0
2075   PMD: Creating pcap-backed ethdev on numa socket 0
2076   Port 0 is attached. Now total ports is 1
2077   Done
2078
2079In this case, identifier is ``net_pcap0``.
2080This identifier format is the same as ``--vdev`` format of DPDK applications.
2081
2082For example, to re-attach a bonded port which has been previously detached,
2083the mode and slave parameters must be given.
2084
2085.. code-block:: console
2086
2087   testpmd> port attach net_bond_0,mode=0,slave=1
2088   Attaching a new port...
2089   EAL: Initializing pmd_bond for net_bond_0
2090   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2091   Port 0 is attached. Now total ports is 1
2092   Done
2093
2094
2095port detach
2096~~~~~~~~~~~
2097
2098Detach a specific port::
2099
2100   testpmd> port detach (port_id)
2101
2102Before detaching a port, the port should be stopped and closed.
2103
2104For example, to detach a pci device port 0.
2105
2106.. code-block:: console
2107
2108   testpmd> port stop 0
2109   Stopping ports...
2110   Done
2111   testpmd> port close 0
2112   Closing ports...
2113   Done
2114
2115   testpmd> port detach 0
2116   Detaching a port...
2117   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2118   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
2119   EAL:   PCI memory unmapped at 0x7f83bfa00000
2120   EAL:   PCI memory unmapped at 0x7f83bfa80000
2121   Done
2122
2123
2124For example, to detach a virtual device port 0.
2125
2126.. code-block:: console
2127
2128   testpmd> port stop 0
2129   Stopping ports...
2130   Done
2131   testpmd> port close 0
2132   Closing ports...
2133   Done
2134
2135   testpmd> port detach 0
2136   Detaching a port...
2137   PMD: Closing pcap ethdev on numa socket 0
2138   Port 'net_pcap0' is detached. Now total ports is 0
2139   Done
2140
2141To remove a pci device completely from the system, first detach the port from testpmd.
2142Then the device should be moved under kernel management.
2143Finally the device can be removed using kernel pci hotplug functionality.
2144
2145For example, to move a pci device under kernel management:
2146
2147.. code-block:: console
2148
2149   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2150
2151   ./usertools/dpdk-devbind.py --status

2262
2263Enable or disable packet drop on all RX queues of all ports when no receive buffers available::
2264
2265   testpmd> port config all drop-en (on|off)
2266
2267Packet dropping when no receive buffers available is off by default.
2268
2269The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2270
2271port config - RSS
2272~~~~~~~~~~~~~~~~~
2273
2274Set the RSS (Receive Side Scaling) mode on or off::

2276   testpmd> port config all rss (all|default|eth|vlan|ip|tcp|udp|sctp|ether|port|vxlan|geneve|nvgre|vxlan-gpe|l2tpv3|esp|ah|pfcp|ecpri|mpls|none)
2277
2278RSS is on by default.
2279
2280The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp.
2281
2282The ``default`` option enables all supported RSS types reported by device info.
2283
2284The ``none`` option is equivalent to the ``--disable-rss`` command-line option.

2297
2298   testpmd> port config (port_id) dcb vt (on|off) (traffic_class) pfc (on|off)
2299
2300The traffic class should be 4 or 8.
2301
2302port config - Burst
2303~~~~~~~~~~~~~~~~~~~
2304
2305Set the number of packets per burst::
2306
2307   testpmd> port config all burst (value)
2308
2309This is equivalent to the ``--burst`` command-line option.
2310
2311port config - Threshold
2312~~~~~~~~~~~~~~~~~~~~~~~
2313
2314Set thresholds for TX/RX queues::
2315
2316   testpmd> port config all (threshold) (value)
2317
2318Where the threshold type can be:
2319
2320* ``txpt:`` Set the prefetch threshold register of the TX rings, 0 <= value <= 255.
2321
2322* ``txht:`` Set the host threshold register of the TX rings, 0 <= value <= 255.
2323

2334* ``rxfreet:`` Set the transmit free threshold of the RX rings, 0 <= value <= rxd.
2335
2336* ``txrst:`` Set the transmit RS bit threshold of TX rings, 0 <= value <= txd.
2337
2338These threshold options are also available from the command-line.
2339
2340port config pctype mapping
2341~~~~~~~~~~~~~~~~~~~~~~~~~~

2356
2357port config input set
2358~~~~~~~~~~~~~~~~~~~~~
2359
2360Config RSS/FDIR/FDIR flexible payload input set for some pctype::

2364	    (get|set|clear) field (field_idx)
2365
2366Clear RSS/FDIR/FDIR flexible payload input set for some pctype::
2367
2368   testpmd> port config (port_id) pctype (pctype_id) \
2369            (hash_inset|fdir_inset|fdir_flx_inset) clear all
2370
2371where:

2390
2391port config dynf
2392~~~~~~~~~~~~~~~~
2393
2394Set/clear dynamic flag per port.
2395testpmd will register this flag in the mbuf (same registration
2396for both Tx and Rx). Then set/clear this flag for each Tx
2397packet sent from this port. The set bit only works for Tx packet::
2398
2399   testpmd> port config (port_id) dynf (name) (set|clear)
2400
2401port config mtu
2402~~~~~~~~~~~~~~~

2429
2430Device Functions
2431----------------
2432
2433The following sections show functions for device operations.
2434
2435device detach
2436~~~~~~~~~~~~~
2437
2438Detach a device specified by pci address or virtual device args::
2439
2440   testpmd> device detach (identifier)
2441
2442Before detaching a device associated with ports, the ports should be stopped and closed.
2443
2444For example, to detach a pci device whose address is 0002:03:00.0.
2445
2446.. code-block:: console
2447
2448    testpmd> device detach 0002:03:00.0
2449    Removing a device...
2450    Port 1 is now closed
2451    EAL: Releasing pci mapped resource for 0002:03:00.0
2452    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2453    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2454    Device 0002:03:00.0 is detached
2455    Now total ports is 1
2456
2457For example, to detach a port created by pcap PMD.
2458
2459.. code-block:: console
2460
2461    testpmd> device detach net_pcap0
2462    Removing a device...
2463    Port 0 is now closed
2464    Device net_pcap0 is detached
2465    Now total ports is 0
2466    Done
2467
2468In this case, identifier is ``net_pcap0``.
2469This identifier format is the same as ``--vdev`` format of DPDK applications.
2470
2471Link Bonding Functions

2496For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2497
2498   testpmd> add bonding slave 6 10
2499
2500
2501remove bonding slave
2502~~~~~~~~~~~~~~~~~~~~
2503
2504Removes an Ethernet slave device from a Link Bonding device::
2505
2506   testpmd> remove bonding slave (slave id) (port id)
2507
2508For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::

2552For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2553
2554   testpmd> set bonding balance_xmit_policy 10 l34
2555
2556
2557set bonding mon_period
2558~~~~~~~~~~~~~~~~~~~~~~

2561
2562This adds support for PMD slave devices which do not support link status interrupts.
2563When the mon_period is set to a value greater than 0 then all PMD's which do not support
2564link status ISR will be queried every polling interval to check if their link status has changed::
2565
2566   testpmd> set bonding mon_period (port_id) (value)

3224Filter Functions
3225----------------
3226
3227This section details the available filter functions that are available.
3228
3229Note these functions interface the deprecated legacy filtering framework,
3230superseded by *rte_flow*. See `Flow rules management`_.
3231
3232.. _testpmd_flow_director:
3233
3234flow_director_mask
3235~~~~~~~~~~~~~~~~~~
3236
3237Set flow director's input masks::
3238
3239   flow_director_mask (port_id) mode IP vlan (vlan_value) \
3240                      src_mask (ipv4_src) (ipv6_src) (src_port) \
3241                      dst_mask (ipv4_dst) (ipv6_dst) (dst_port)
3242
3243   flow_director_mask (port_id) mode MAC-VLAN vlan (vlan_value)
3244

3271
3272Flow rules management
3273---------------------
3274
3275Control of the generic flow API (*rte_flow*) is fully exposed through the
3276``flow`` command (validation, creation, destruction, queries and operation
3277modes).
3278
3279Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3280features simultaneously may cause undefined side-effects and is therefore
3281not recommended.
3282
3283``flow`` syntax
3284~~~~~~~~~~~~~~~
3285
3286Because the ``flow`` command uses dynamic tokens to handle the large number
3287of possible flow rules combinations, its behavior differs slightly from
3288other commands, in particular:
3289
3290- Pressing *?* or the *<tab>* key displays contextual help for the current
3291  token, not that of the entire command.
3292
3293- Optional and repeated parameters are supported (provided they are listed
3294  in the contextual help).
3295
3296The first parameter stands for the operation mode. Possible operations and
3297their general syntax are described below. They are covered in detail in the
3298following sections.
3299
3300- Check whether a flow rule can be created::
3301
3302   flow validate {port_id}
3303       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3304       pattern {item} [/ {item} [...]] / end
3305       actions {action} [/ {action} [...]] / end
3306
3307- Create a flow rule::
3308
3309   flow create {port_id}
3310       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3311       pattern {item} [/ {item} [...]] / end
3312       actions {action} [/ {action} [...]] / end
3313
3314- Destroy specific flow rules::
3315
3316   flow destroy {port_id} rule {rule_id} [...]
3317
3318- Destroy all flow rules::
3319
3320   flow flush {port_id}
3321
3322- Query an existing flow rule::
3323
3324   flow query {port_id} {rule_id} {action}
3325
3326- List existing flow rules sorted by priority, filtered by group
3327  identifiers::
3328
3329   flow list {port_id} [group {group_id}] [...]
3330
3331- Restrict ingress traffic to the defined flow rules::
3332
3333   flow isolate {port_id} {boolean}
3334
3335- Dump internal representation information of all flows in hardware::
3336
3337   flow dump {port_id} all {output_file}
3338
3339  for one flow::
3340
3341   flow dump {port_id} rule {rule_id} {output_file}
3342
3343- List and destroy aged flow rules::
3344
3345   flow aged {port_id} [destroy]
3346
3347- Tunnel offload - create a tunnel stub::
3348
3349   flow tunnel create {port_id} type {tunnel_type}
3350
3351- Tunnel offload - destroy a tunnel stub::
3352
3353   flow tunnel destroy {port_id} id {tunnel_id}
3354
3355- Tunnel offload - list port tunnel stubs::
3356
3357   flow tunnel list {port_id}
3358
3359Creating a tunnel stub for offload
3360~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3361
3362``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3363
3364   flow tunnel create {port_id} type {tunnel_type}
3365
3366If successful, it will return a tunnel stub ID usable with other commands::
3367
3368   port [...]: flow tunnel #[...] type [...]
3369
3370Tunnel stub ID is relative to a port.
3371
3372Destroying tunnel offload stub
3373~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3374
3375``flow tunnel destroy`` destroy port tunnel stub::
3376
3377   flow tunnel destroy {port_id} id {tunnel_id}
3378
3379Listing tunnel offload stubs
3380~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3381
3382``flow tunnel list`` list port tunnel offload stubs::
3383
3384   flow tunnel list {port_id}
3385
3386Validating flow rules
3387~~~~~~~~~~~~~~~~~~~~~
3388
3389``flow validate`` reports whether a flow rule would be accepted by the
3390underlying device in its current state but stops short of creating it. It is
3391bound to ``rte_flow_validate()``::
3392
3393   flow validate {port_id}
3394      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3395      pattern {item} [/ {item} [...]] / end
3396      actions {action} [/ {action} [...]] / end
3397
3398If successful, it will show::
3399
3400   Flow rule validated
3401
3402Otherwise it will show an error message of the form::
3403
3404   Caught error type [...] ([...]): [...]
3405
3406This command uses the same parameters as ``flow create``, their format is
3407described in `Creating flow rules`_.
3408
3409Check whether redirecting any Ethernet packet received on port 0 to RX queue
3410index 6 is supported::
3411
3412   testpmd> flow validate 0 ingress pattern eth / end
3413      actions queue index 6 / end
3414   Flow rule validated
3415   testpmd>
3416
3417Port 0 does not support TCPv6 rules::
3418
3419   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3420      actions drop / end
3421   Caught error type 9 (specific pattern item): Invalid argument
3422   testpmd>
3423
3424Creating flow rules
3425~~~~~~~~~~~~~~~~~~~
3426
3427``flow create`` validates and creates the specified flow rule. It is bound
3428to ``rte_flow_create()``::
3429
3430   flow create {port_id}
3431      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3432      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3433      pattern {item} [/ {item} [...]] / end
3434      actions {action} [/ {action} [...]] / end
3435
3436If successful, it will return a flow rule ID usable with other commands::
3437
3438   Flow rule #[...] created
3439
3440Otherwise it will show an error message of the form::
3441
3442   Caught error type [...] ([...]): [...]
3443
3444Parameters describe in the following order:
3445
3446- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3447- Tunnel offload specification (tunnel_set, tunnel_match)
3448- A matching pattern, starting with the *pattern* token and terminated by an
3449  *end* pattern item.
3450- Actions, starting with the *actions* token and terminated by an *end*
3451  action.
3452
3453These translate directly to *rte_flow* objects provided as-is to the
3454underlying functions.
3455
3456The shortest valid definition only comprises mandatory tokens::
3457
3458   testpmd> flow create 0 pattern end actions end
3459
3460Note that PMDs may refuse rules that essentially do nothing such as this
3461one.
3462
3463**All unspecified object values are automatically initialized to 0.**
3464
3465Attributes
3466^^^^^^^^^^
3467
3468These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3469specified before the ``pattern`` token.
3470
3471- ``group {group id}``: priority group.
3472- ``priority {level}``: priority level within group.
3473- ``ingress``: rule applies to ingress traffic.
3474- ``egress``: rule applies to egress traffic.
3475- ``transfer``: apply rule directly to endpoints found in pattern.
3476
3477Each instance of an attribute specified several times overrides the previous
3478value as shown below (group 4 is used)::
3479
3480   testpmd> flow create 0 group 42 group 24 group 4 [...]
3481
3482Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3483
3484While not specifying a direction is an error, some rules may allow both
3485simultaneously.
3486
3487Most rules affect RX therefore contain the ``ingress`` token::
3488
3489   testpmd> flow create 0 ingress pattern [...]
3490
3491Tunnel offload
3492^^^^^^^^^^^^^^
3493
3494Indicate tunnel offload rule type
3495
3496- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3497- ``tunnel_match {tunnel_id}``:  mark rule as tunel offload match type.
3498
3499Matching pattern
3500^^^^^^^^^^^^^^^^
3501
3502A matching pattern starts after the ``pattern`` token. It is made of pattern
3503items and is terminated by a mandatory ``end`` item.
3504
3505Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3506rte_flow_item_type``).
3507
3508The ``/`` token is used as a separator between pattern items as shown
3509below::
3510
3511   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3512
3513Note that protocol items like these must be stacked from lowest to highest
3514layer to make sense. For instance, the following rule is either invalid or
3515unlikely to match any packet::
3516
3517   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3518
3519More information on these restrictions can be found in the *rte_flow*
3520documentation.
3521
3522Several items support additional specification structures, for example
3523``ipv4`` allows specifying source and destination addresses as follows::
3524
3525   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3526      dst is 10.2.0.0 / end [...]
3527
3528This rule matches all IPv4 traffic with the specified properties.
3529
3530In this example, ``src`` and ``dst`` are field names of the underlying
3531``struct rte_flow_item_ipv4`` object. All item properties can be specified
3532in a similar fashion.
3533
3534The ``is`` token means that the subsequent value must be matched exactly,
3535and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3536accordingly. Possible assignment tokens are:
3537
3538- ``is``: match value perfectly (with full bit-mask).
3539- ``spec``: match value according to configured bit-mask.
3540- ``last``: specify upper bound to establish a range.
3541- ``mask``: specify bit-mask with relevant bits set to one.
3542- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3543
3544These yield identical results::
3545
3546   ipv4 src is 10.1.1.1
3547
3548::
3549
3550   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3551
3552::
3553
3554   ipv4 src spec 10.1.1.1 src prefix 32
3555
3556::
3557
3558   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3559
3560::
3561
3562   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3563
3564Inclusive ranges can be defined with ``last``::
3565
3566   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3567
3568Note that ``mask`` affects both ``spec`` and ``last``::
3569
3570   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3571      # matches 10.1.0.0 to 10.2.255.255
3572
3573Properties can be modified multiple times::
3574
3575   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3576
3577::
3578
3579   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3580

3808Actions list
3809^^^^^^^^^^^^
3810
3811A list of actions starts after the ``actions`` token in the same fashion as
3812`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3813terminated by a mandatory ``end`` action.
3814
3815Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3816rte_flow_action_type``).
3817
3818Dropping all incoming UDPv4 packets can be expressed as follows::
3819
3820   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3821      actions drop / end
3822
3823Several actions have configurable properties which must be specified when
3824there is no valid default value. For example, ``queue`` requires a target
3825queue index.
3826
3827This rule redirects incoming UDPv4 traffic to queue index 6::
3828
3829   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3830      actions queue index 6 / end
3831
3832While this one could be rejected by PMDs (unspecified queue index)::
3833
3834   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3835      actions queue / end
3836
3837As defined by *rte_flow*, the list is not ordered, all actions of a given
3838rule are performed simultaneously. These are equivalent::
3839
3840   queue index 6 / void / mark id 42 / end
3841
3842::
3843
3844   void / mark id 42 / queue index 6 / end
3845
3846All actions in a list should have different types, otherwise only the last
3847action of a given type is taken into account::
3848
3849   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3850
3851::
3852
3853   drop / drop / drop / end # drop is performed only once
3854
3855::
3856
3857   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3858
3859Considering they are performed simultaneously, opposite and overlapping
3860actions can sometimes be combined when the end result is unambiguous::
3861
3862   drop / queue index 6 / end # drop has no effect
3863
3864::
3865
3866   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3867
3868::
3869
3870   drop / passthru / end # drop has no effect
3871
3872Note that PMDs may still refuse such combinations.

4083Destroying flow rules
4084~~~~~~~~~~~~~~~~~~~~~
4085
4086``flow destroy`` destroys one or more rules from their rule ID (as returned
4087by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4088times as necessary::
4089
4090   flow destroy {port_id} rule {rule_id} [...]
4091
4092If successful, it will show::
4093
4094   Flow rule #[...] destroyed
4095
4096It does not report anything for rule IDs that do not exist. The usual error
4097message is shown when a rule cannot be destroyed::
4098
4099   Caught error type [...] ([...]): [...]
4100
4101``flow flush`` destroys all rules on a device and does not take extra
4102arguments. It is bound to ``rte_flow_flush()``::
4103
4104   flow flush {port_id}
4105
4106Any errors are reported as above.
4107
4108Creating several rules and destroying them::
4109
4110   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4111      actions queue index 2 / end
4112   Flow rule #0 created
4113   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4114      actions queue index 3 / end
4115   Flow rule #1 created
4116   testpmd> flow destroy 0 rule 0 rule 1
4117   Flow rule #1 destroyed
4118   Flow rule #0 destroyed
4119   testpmd>
4120
4121The same result can be achieved using ``flow flush``::
4122
4123   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4124      actions queue index 2 / end
4125   Flow rule #0 created
4126   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4127      actions queue index 3 / end
4128   Flow rule #1 created
4129   testpmd> flow flush 0
4130   testpmd>
4131
4132Non-existent rule IDs are ignored::
4133
4134   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4135      actions queue index 2 / end
4136   Flow rule #0 created
4137   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4138      actions queue index 3 / end
4139   Flow rule #1 created
4140   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4141   testpmd>
4142   testpmd> flow destroy 0 rule 0
4143   Flow rule #0 destroyed
4144   testpmd>
4145
4146Querying flow rules
4147~~~~~~~~~~~~~~~~~~~
4148
4149``flow query`` queries a specific action of a flow rule having that
4150ability. Such actions collect information that can be reported using this
4151command. It is bound to ``rte_flow_query()``::
4152
4153   flow query {port_id} {rule_id} {action}
4154
4155If successful, it will display either the retrieved data for known actions
4156or the following message::
4157
4158   Cannot display result for action type [...] ([...])
4159
4160Otherwise, it will complain either that the rule does not exist or that some
4161error occurred::
4162
4163   Flow rule #[...] not found
4164
4165::
4166
4167   Caught error type [...] ([...]): [...]
4168
4169Currently only the ``count`` action is supported. This action reports the
4170number of packets that hit the flow rule and the total number of bytes. Its
4171output has the following format::
4172
4173   count:
4174    hits_set: [...] # whether "hits" contains a valid value
4175    bytes_set: [...] # whether "bytes" contains a valid value
4176    hits: [...] # number of packets
4177    bytes: [...] # number of bytes
4178
4179Querying counters for TCPv6 packets redirected to queue 6::
4180
4181   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4182      actions queue index 6 / count / end
4183   Flow rule #4 created
4184   testpmd> flow query 0 4 count
4185   count:
4186    hits_set: 1
4187    bytes_set: 0
4188    hits: 386446
4189    bytes: 0
4190   testpmd>
4191
4192Listing flow rules
4193~~~~~~~~~~~~~~~~~~
4194
4195``flow list`` lists existing flow rules sorted by priority and optionally
4196filtered by group identifiers::
4197
4198   flow list {port_id} [group {group_id}] [...]
4199
4200This command only fails with the following message if the device does not
4201exist::
4202
4203   Invalid port [...]
4204
4205Output consists of a header line followed by a short description of each
4206flow rule, one per line. There is no output at all when no flow rules are
4207configured on the device::
4208
4209   ID      Group   Prio    Attr    Rule
4210   [...]   [...]   [...]   [...]   [...]
4211
4212``Attr`` column flags:
4213
4214- ``i`` for ``ingress``.
4215- ``e`` for ``egress``.
4216
4217Creating several flow rules and listing them::
4218
4219   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4220      actions queue index 6 / end
4221   Flow rule #0 created
4222   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4223      actions queue index 2 / end
4224   Flow rule #1 created
4225   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4226      actions rss queues 6 7 8 end / end
4227   Flow rule #2 created
4228   testpmd> flow list 0
4229   ID      Group   Prio    Attr    Rule
4230   0       0       0       i-      ETH IPV4 => QUEUE
4231   1       0       0       i-      ETH IPV6 => QUEUE
4232   2       0       5       i-      ETH IPV4 UDP => RSS
4233   testpmd>
4234
4235Rules are sorted by priority (i.e. group ID first, then priority level)::
4236
4237   testpmd> flow list 1
4238   ID      Group   Prio    Attr    Rule
4239   0       0       0       i-      ETH => COUNT
4240   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4241   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4242   1       24      0       i-      ETH IPV4 UDP => QUEUE
4243   4       24      10      i-      ETH IPV4 TCP => DROP
4244   3       24      20      i-      ETH IPV4 => DROP
4245   2       24      42      i-      ETH IPV4 UDP => QUEUE
4246   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4247   testpmd>
4248
4249Output can be limited to specific groups::
4250
4251   testpmd> flow list 1 group 0 group 63
4252   ID      Group   Prio    Attr    Rule
4253   0       0       0       i-      ETH => COUNT
4254   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4255   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4256   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4257   testpmd>
4258
4259Toggling isolated mode
4260~~~~~~~~~~~~~~~~~~~~~~
4261
4262``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4263must only be injected from the defined flow rules; that no default traffic
4264is expected outside those rules and the driver is free to assign more
4265resources to handle them. It is bound to ``rte_flow_isolate()``::
4266
4267 flow isolate {port_id} {boolean}
4268
4269If successful, enabling or disabling isolated mode shows either::
4270
4271 Ingress traffic on port [...]
4272    is now restricted to the defined flow rules
4273
4274Or::
4275
4276 Ingress traffic on port [...]
4277    is not restricted anymore to the defined flow rules
4278
4279Otherwise, in case of error::
4280
4281   Caught error type [...] ([...]): [...]
4282
4283Mainly due to its side effects, PMDs supporting this mode may not have the
4284ability to toggle it more than once without reinitializing affected ports
4285first (e.g. by exiting testpmd).
4286
4287Enabling isolated mode::
4288
4289 testpmd> flow isolate 0 true
4290 Ingress traffic on port 0 is now restricted to the defined flow rules
4291 testpmd>
4292
4293Disabling isolated mode::
4294
4295 testpmd> flow isolate 0 false
4296 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4297 testpmd>
4298
4299Dumping HW internal information
4300~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4301
4302``flow dump`` dumps the hardware's internal representation information of
4303all flows. It is bound to ``rte_flow_dev_dump()``::
4304
4305   flow dump {port_id} {output_file}
4306
4307If successful, it will show::
4308
4309   Flow dump finished
4310
4311Otherwise, it will complain error occurred::
4312
4313   Caught error type [...] ([...]): [...]
4314
4315Listing and destroying aged flow rules
4316~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4317
4318``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4319and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4320
4321   flow aged {port_id} [destroy]
4322
4323Listing current aged flow rules::
4324
4325   testpmd> flow aged 0
4326   Port 0 total aged flows: 0
4327   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4328      actions age timeout 5 / queue index 0 /  end
4329   Flow rule #0 created
4330   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4331      actions age timeout 4 / queue index 0 /  end
4332   Flow rule #1 created
4333   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4334      actions age timeout 2 / queue index 0 /  end

4338   Flow rule #3 created
4339
4340
4341Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4342information, all the aged flows are sorted by the longest timeout time. For example, if
4343those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4344will be ID 3, ID 1, ID 0::
4345
4346   testpmd> flow aged 0
4347   Port 0 total aged flows: 4
4348   ID      Group   Prio    Attr

4353
4354If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.

4372Creating indirect actions
4373~~~~~~~~~~~~~~~~~~~~~~~~~
4374
4375``flow indirect_action {port_id} create`` creates indirect action with optional
4376indirect action ID. It is bound to ``rte_flow_action_handle_create()``::
4377
4378   flow indirect_action {port_id} create [action_id {indirect_action_id}]
4379      [ingress] [egress] [transfer] action {action} / end
4380
4381If successful, it will show::
4382
4383   Indirect action #[...] created
4384
4385Otherwise, it will complain either that indirect action already exists or that
4386some error occurred::
4387
4388   Indirect action #[...] is already assigned, delete it first
4389
4390::
4391
4392   Caught error type [...] ([...]): [...]
4393
4394Create indirect rss action with id 100 to queues 1 and 2 on port 0::
4395
4396   testpmd> flow indirect_action 0 create action_id 100 \
4397      ingress action rss queues 1 2 end / end
4398
4399Create indirect rss action with id assigned by testpmd to queues 1 and 2 on
4400port 0::
4401
4402	testpmd> flow indirect_action 0 create action_id \
4403		ingress action rss queues 0 1 end / end
4404
4405Updating indirect actions
4406~~~~~~~~~~~~~~~~~~~~~~~~~
4407
4408``flow indirect_action {port_id} update`` updates configuration of the indirect
4409action from its indirect action ID (as returned by
4410``flow indirect_action {port_id} create``). It is bound to
4411``rte_flow_action_handle_update()``::
4412
4413   flow indirect_action {port_id} update {indirect_action_id}
4414      action {action} / end
4415
4416If successful, it will show::
4417
4418   Indirect action #[...] updated
4419
4420Otherwise, it will complain either that indirect action not found or that some
4421error occurred::
4422
4423   Failed to find indirect action #[...] on port [...]
4424
4425::
4426
4427   Caught error type [...] ([...]): [...]
4428
4429Update indirect rss action having id 100 on port 0 with rss to queues 0 and 3
4430(in create example above rss queues were 1 and 2)::
4431
4432   testpmd> flow indirect_action 0 update 100 action rss queues 0 3 end / end
4433
4434Destroying indirect actions
4435~~~~~~~~~~~~~~~~~~~~~~~~~~~
4436
4437``flow indirect_action {port_id} destroy`` destroys one or more indirect actions
4438from their indirect action IDs (as returned by
4439``flow indirect_action {port_id} create``). It is bound to
4440``rte_flow_action_handle_destroy()``::
4441
4442   flow indirect_action {port_id} destroy action_id {indirect_action_id} [...]
4443
4444If successful, it will show::
4445
4446   Indirect action #[...] destroyed
4447
4448It does not report anything for indirect action IDs that do not exist.
4449The usual error message is shown when a indirect action cannot be destroyed::
4450
4451   Caught error type [...] ([...]): [...]
4452
4453Destroy indirect actions having id 100 & 101::
4454
4455   testpmd> flow indirect_action 0 destroy action_id 100 action_id 101
4456
4457Query indirect actions
4458~~~~~~~~~~~~~~~~~~~~~~
4459
4460``flow indirect_action {port_id} query`` queries the indirect action from its
4461indirect action ID (as returned by ``flow indirect_action {port_id} create``).
4462It is bound to ``rte_flow_action_handle_query()``::
4463
4464  flow indirect_action {port_id} query {indirect_action_id}
4465
4466Currently only rss indirect action supported. If successful, it will show::
4467
4468   Indirect RSS action:
4469      refs:[...]
4470
4471Otherwise, it will complain either that indirect action not found or that some
4472error occurred::
4473
4474   Failed to find indirect action #[...] on port [...]
4475
4476::
4477
4478   Caught error type [...] ([...]): [...]
4479
4480Query indirect action having id 100::
4481
4482   testpmd> flow indirect_action 0 query 100
4483
4484Sample QinQ flow rules
4485~~~~~~~~~~~~~~~~~~~~~~
4486
4487Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4488
4489   testpmd> port stop 0
4490   testpmd> vlan set extend on 0
4491
4492The above command sets the inner and outer TPID's to 0x8100.
4493
4494To change the TPID's the following commands should be used::
4495
4496   testpmd> vlan set outer tpid 0x88A8 0
4497   testpmd> vlan set inner tpid 0x8100 0
4498   testpmd> port start 0
4499
4500Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4501
4502::
4503
4504   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4505       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4506   Flow rule #0 validated

4515
4516Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4517
4518::
4519
4520   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4521        vlan tci is 654 / end actions pf / queue index 0 / end
4522   Flow rule #1 validated

4532
4533Sample VXLAN flow rules
4534~~~~~~~~~~~~~~~~~~~~~~~
4535
4536Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4537filter on a port::
4538
4539  testpmd> rx_vxlan_port add 4789 0
4540
4541Create VXLAN rules on port 0 to steer traffic to PF queues.

4961            pattern eth / ipv4 / tcp / integrity value mask 8 value spec 8 / end
4962            actions jump group 1 / end
4963
4964Integrity rule that forwards invalid packets to application.
4965General packet integrity is matched with the ``packet_ok`` bit 0.
4966

4968
4969 testpmd> flow create 0 ingress pattern integrity value mask 1 value spec 0 / end actions queue index 0 / end
4970
4971Sample conntrack rules
4972~~~~~~~~~~~~~~~~~~~~~~
4973
4974Conntrack rules can be set by the following commands
4975
4976Need to construct the connection context with provided information.
4977In the first table, create a flow rule by using conntrack action and jump to
4978the next table. In the next table, create a rule to check the state.
4979
4980::
4981
4982 testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
4983        last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510
4984        last_seq 2632987379 last_ack 2532480967 last_end 2632987379
4985        last_index 0x8
4986 testpmd> set conntrack orig scale 7 fin 0 acked 1 unack_data 0
4987        sent_end 2632987379 reply_end 2633016339 max_win 28960
4988        max_ack 2632987379
4989 testpmd> set conntrack rply scale 7 fin 0 acked 1 unack_data 0
4990        sent_end 2532480967 reply_end 2532546247 max_win 65280
4991        max_ack 2532480967
4992 testpmd> flow indirect_action 0 create ingress action conntrack / end
4993 testpmd> flow create 0 group 3 ingress pattern eth / ipv4 / tcp / end actions indirect 0 / jump group 5 / end
4994 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
4995
4996Construct the conntrack again with only "is_orig" set to 0 (other fields are
4997ignored), then use "update" interface to update the direction. Create flow
4998rules like above for the peer port.
4999
5000::
5001
5002 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
5003
5004Sample meter with policy rules
5005~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5006
5007Meter with policy rules can be created by the following commands:
5008
5009Need to create policy first and actions are set for green/yellow/red colors.
5010Create meter with policy id. Create flow with meter id.
5011
5012Example for policy with meter color action. The purpose is to color the packet
5013to reflect the meter color result.
5014The meter policy action list: ``green -> green, yellow -> yellow, red -> red``.
5015
5016::
5017
5018   testpmd> add port meter profile srtcm_rfc2697 0 13 21504 2688 0 0
5019   testpmd> add port meter policy 0 1 g_actions color type green / end y_actions color type yellow / end
5020            r_actions color type red / end
5021   testpmd> create port meter 0 1 13 1 yes 0xffff 0 0
5022   testpmd> flow create 0 priority 0 ingress group 1 pattern eth / end actions meter mtr_id 1 / end
5023
5024BPF Functions
5025--------------
5026
5027The following sections show functions to load/unload eBPF based filters.
5028
5029bpf-load
5030~~~~~~~~
5031
5032Load an eBPF program as a callback for particular RX/TX queue::
5033
5034   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5035
5036The available load-flags are:
5037
5038* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5039
5040* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5041
5042* ``-``: none.
5043
5044.. note::
5045
5046   You'll need clang v3.7 or above to build bpf program you'd like to load
5047
5048For example:
5049
5050.. code-block:: console
5051
5052   cd examples/bpf
5053   clang -O2 -target bpf -c t1.c
5054
5055Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5056
5057.. code-block:: console
5058
5059   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5060
5061To load (not JITed) t1.o at TX queue 0, port 0:
5062
5063.. code-block:: console
5064
5065   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5066
5067bpf-unload
5068~~~~~~~~~~
5069
5070Unload previously loaded eBPF program for particular RX/TX queue::
5071
5072   testpmd> bpf-unload rx|tx (portid) (queueid)
5073
5074For example to unload BPF filter from TX queue 0, port 0:
5075
5076.. code-block:: console
5077
5078   testpmd> bpf-unload tx 0 0
5079
