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::

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

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

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

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
2472----------------------
2473
2474The Link Bonding functions make it possible to dynamically create and
2475manage link bonding devices from within testpmd interactive prompt.

2493
2494   testpmd> add bonding slave (slave id) (port id)
2495
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::

2551
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)
2567
2568For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

2594
2595   testpmd> show bonding config (port id)
2596
2597For example,
2598to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
2599in balance mode with a transmission policy of layer 2+3::
2600
2601   testpmd> show bonding config 9
2602        Bonding mode: 2
2603        Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23

3218Filter Functions
3219----------------
3220
3221This section details the available filter functions that are available.
3222
3223Note these functions interface the deprecated legacy filtering framework,
3224superseded by *rte_flow*. See `Flow rules management`_.
3225
3226.. _testpmd_flow_director:
3227
3228flow_director_mask
3229~~~~~~~~~~~~~~~~~~
3230
3231Set flow director's input masks::
3232
3233   flow_director_mask (port_id) mode IP vlan (vlan_value) \
3234                      src_mask (ipv4_src) (ipv6_src) (src_port) \
3235                      dst_mask (ipv4_dst) (ipv6_dst) (dst_port)
3236
3237   flow_director_mask (port_id) mode MAC-VLAN vlan (vlan_value)
3238
3239   flow_director_mask (port_id) mode Tunnel vlan (vlan_value) \

3241                      tunnel-id (tunnel_id_value)
3242
3243Example, to set flow director mask on port 0::
3244
3245   testpmd> flow_director_mask 0 mode IP vlan 0xefff \
3246            src_mask 255.255.255.255 \

3250
3251flow_director_flex_payload
3252~~~~~~~~~~~~~~~~~~~~~~~~~~
3253
3254Configure flexible payload selection::
3255

3265
3266Flow rules management
3267---------------------
3268
3269Control of the generic flow API (*rte_flow*) is fully exposed through the
3270``flow`` command (validation, creation, destruction, queries and operation
3271modes).
3272
3273Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3274features simultaneously may cause undefined side-effects and is therefore
3275not recommended.
3276
3277``flow`` syntax
3278~~~~~~~~~~~~~~~
3279
3280Because the ``flow`` command uses dynamic tokens to handle the large number
3281of possible flow rules combinations, its behavior differs slightly from
3282other commands, in particular:
3283
3284- Pressing *?* or the *<tab>* key displays contextual help for the current
3285  token, not that of the entire command.
3286
3287- Optional and repeated parameters are supported (provided they are listed
3288  in the contextual help).
3289
3290The first parameter stands for the operation mode. Possible operations and
3291their general syntax are described below. They are covered in detail in the
3292following sections.
3293
3294- Check whether a flow rule can be created::

3340
3341- Tunnel offload - create a tunnel stub::
3342
3343   flow tunnel create {port_id} type {tunnel_type}
3344
3345- Tunnel offload - destroy a tunnel stub::
3346
3347   flow tunnel destroy {port_id} id {tunnel_id}
3348
3349- Tunnel offload - list port tunnel stubs::
3350
3351   flow tunnel list {port_id}
3352
3353Creating a tunnel stub for offload
3354~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3355
3356``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3357
3358   flow tunnel create {port_id} type {tunnel_type}
3359
3360If successful, it will return a tunnel stub ID usable with other commands::
3361
3362   port [...]: flow tunnel #[...] type [...]
3363
3364Tunnel stub ID is relative to a port.
3365
3366Destroying tunnel offload stub
3367~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3368
3369``flow tunnel destroy`` destroy port tunnel stub::
3370
3371   flow tunnel destroy {port_id} id {tunnel_id}
3372
3373Listing tunnel offload stubs
3374~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3375
3376``flow tunnel list`` list port tunnel offload stubs::
3377
3378   flow tunnel list {port_id}
3379
3380Validating flow rules
3381~~~~~~~~~~~~~~~~~~~~~
3382
3383``flow validate`` reports whether a flow rule would be accepted by the
3384underlying device in its current state but stops short of creating it. It is
3385bound to ``rte_flow_validate()``::
3386
3387   flow validate {port_id}
3388      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3389      pattern {item} [/ {item} [...]] / end
3390      actions {action} [/ {action} [...]] / end
3391
3392If successful, it will show::
3393
3394   Flow rule validated
3395
3396Otherwise it will show an error message of the form::
3397
3398   Caught error type [...] ([...]): [...]
3399
3400This command uses the same parameters as ``flow create``, their format is
3401described in `Creating flow rules`_.
3402
3403Check whether redirecting any Ethernet packet received on port 0 to RX queue
3404index 6 is supported::
3405
3406   testpmd> flow validate 0 ingress pattern eth / end
3407      actions queue index 6 / end
3408   Flow rule validated
3409   testpmd>
3410
3411Port 0 does not support TCPv6 rules::
3412
3413   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3414      actions drop / end
3415   Caught error type 9 (specific pattern item): Invalid argument
3416   testpmd>
3417
3418Creating flow rules
3419~~~~~~~~~~~~~~~~~~~
3420
3421``flow create`` validates and creates the specified flow rule. It is bound
3422to ``rte_flow_create()``::
3423
3424   flow create {port_id}
3425      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3426      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3427      pattern {item} [/ {item} [...]] / end
3428      actions {action} [/ {action} [...]] / end
3429
3430If successful, it will return a flow rule ID usable with other commands::
3431
3432   Flow rule #[...] created
3433
3434Otherwise it will show an error message of the form::
3435
3436   Caught error type [...] ([...]): [...]
3437
3438Parameters describe in the following order:
3439
3440- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3441- Tunnel offload specification (tunnel_set, tunnel_match)
3442- A matching pattern, starting with the *pattern* token and terminated by an
3443  *end* pattern item.
3444- Actions, starting with the *actions* token and terminated by an *end*
3445  action.
3446
3447These translate directly to *rte_flow* objects provided as-is to the
3448underlying functions.
3449
3450The shortest valid definition only comprises mandatory tokens::
3451
3452   testpmd> flow create 0 pattern end actions end
3453
3454Note that PMDs may refuse rules that essentially do nothing such as this
3455one.
3456
3457**All unspecified object values are automatically initialized to 0.**
3458
3459Attributes
3460^^^^^^^^^^
3461
3462These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3463specified before the ``pattern`` token.
3464
3465- ``group {group id}``: priority group.
3466- ``priority {level}``: priority level within group.
3467- ``ingress``: rule applies to ingress traffic.
3468- ``egress``: rule applies to egress traffic.
3469- ``transfer``: apply rule directly to endpoints found in pattern.
3470
3471Each instance of an attribute specified several times overrides the previous
3472value as shown below (group 4 is used)::
3473
3474   testpmd> flow create 0 group 42 group 24 group 4 [...]
3475
3476Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3477
3478While not specifying a direction is an error, some rules may allow both
3479simultaneously.
3480
3481Most rules affect RX therefore contain the ``ingress`` token::
3482
3483   testpmd> flow create 0 ingress pattern [...]
3484
3485Tunnel offload
3486^^^^^^^^^^^^^^
3487
3488Indicate tunnel offload rule type
3489
3490- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3491- ``tunnel_match {tunnel_id}``:  mark rule as tunel offload match type.
3492
3493Matching pattern
3494^^^^^^^^^^^^^^^^
3495
3496A matching pattern starts after the ``pattern`` token. It is made of pattern
3497items and is terminated by a mandatory ``end`` item.
3498
3499Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3500rte_flow_item_type``).
3501
3502The ``/`` token is used as a separator between pattern items as shown
3503below::
3504
3505   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3506
3507Note that protocol items like these must be stacked from lowest to highest
3508layer to make sense. For instance, the following rule is either invalid or
3509unlikely to match any packet::
3510
3511   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3512
3513More information on these restrictions can be found in the *rte_flow*
3514documentation.
3515
3516Several items support additional specification structures, for example
3517``ipv4`` allows specifying source and destination addresses as follows::
3518
3519   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3520      dst is 10.2.0.0 / end [...]
3521
3522This rule matches all IPv4 traffic with the specified properties.
3523
3524In this example, ``src`` and ``dst`` are field names of the underlying
3525``struct rte_flow_item_ipv4`` object. All item properties can be specified
3526in a similar fashion.
3527
3528The ``is`` token means that the subsequent value must be matched exactly,
3529and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3530accordingly. Possible assignment tokens are:
3531
3532- ``is``: match value perfectly (with full bit-mask).
3533- ``spec``: match value according to configured bit-mask.
3534- ``last``: specify upper bound to establish a range.
3535- ``mask``: specify bit-mask with relevant bits set to one.
3536- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3537
3538These yield identical results::
3539
3540   ipv4 src is 10.1.1.1
3541
3542::
3543
3544   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3545
3546::
3547
3548   ipv4 src spec 10.1.1.1 src prefix 32
3549
3550::
3551
3552   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3553
3554::
3555
3556   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3557
3558Inclusive ranges can be defined with ``last``::
3559
3560   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3561
3562Note that ``mask`` affects both ``spec`` and ``last``::
3563
3564   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3565      # matches 10.1.0.0 to 10.2.255.255
3566
3567Properties can be modified multiple times::
3568
3569   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3570
3571::
3572
3573   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3574

3797
3798Actions list
3799^^^^^^^^^^^^
3800
3801A list of actions starts after the ``actions`` token in the same fashion as
3802`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3803terminated by a mandatory ``end`` action.
3804
3805Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3806rte_flow_action_type``).
3807
3808Dropping all incoming UDPv4 packets can be expressed as follows::
3809
3810   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3811      actions drop / end
3812
3813Several actions have configurable properties which must be specified when
3814there is no valid default value. For example, ``queue`` requires a target
3815queue index.
3816
3817This rule redirects incoming UDPv4 traffic to queue index 6::
3818
3819   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3820      actions queue index 6 / end
3821
3822While this one could be rejected by PMDs (unspecified queue index)::
3823
3824   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3825      actions queue / end
3826
3827As defined by *rte_flow*, the list is not ordered, all actions of a given
3828rule are performed simultaneously. These are equivalent::
3829
3830   queue index 6 / void / mark id 42 / end
3831
3832::
3833
3834   void / mark id 42 / queue index 6 / end
3835
3836All actions in a list should have different types, otherwise only the last
3837action of a given type is taken into account::
3838
3839   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3840
3841::
3842
3843   drop / drop / drop / end # drop is performed only once
3844
3845::
3846
3847   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3848
3849Considering they are performed simultaneously, opposite and overlapping
3850actions can sometimes be combined when the end result is unambiguous::
3851
3852   drop / queue index 6 / end # drop has no effect
3853
3854::
3855
3856   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3857
3858::
3859
3860   drop / passthru / end # drop has no effect
3861
3862Note that PMDs may still refuse such combinations.

4073Destroying flow rules
4074~~~~~~~~~~~~~~~~~~~~~
4075
4076``flow destroy`` destroys one or more rules from their rule ID (as returned
4077by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4078times as necessary::
4079
4080   flow destroy {port_id} rule {rule_id} [...]
4081
4082If successful, it will show::
4083
4084   Flow rule #[...] destroyed
4085
4086It does not report anything for rule IDs that do not exist. The usual error
4087message is shown when a rule cannot be destroyed::
4088
4089   Caught error type [...] ([...]): [...]
4090
4091``flow flush`` destroys all rules on a device and does not take extra
4092arguments. It is bound to ``rte_flow_flush()``::
4093
4094   flow flush {port_id}
4095
4096Any errors are reported as above.
4097
4098Creating several rules and destroying them::
4099
4100   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4101      actions queue index 2 / end
4102   Flow rule #0 created
4103   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4104      actions queue index 3 / end
4105   Flow rule #1 created
4106   testpmd> flow destroy 0 rule 0 rule 1
4107   Flow rule #1 destroyed
4108   Flow rule #0 destroyed
4109   testpmd>
4110
4111The same result can be achieved using ``flow flush``::
4112
4113   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4114      actions queue index 2 / end
4115   Flow rule #0 created
4116   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4117      actions queue index 3 / end
4118   Flow rule #1 created
4119   testpmd> flow flush 0
4120   testpmd>
4121
4122Non-existent rule IDs are ignored::
4123
4124   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4125      actions queue index 2 / end
4126   Flow rule #0 created
4127   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4128      actions queue index 3 / end
4129   Flow rule #1 created
4130   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4131   testpmd>
4132   testpmd> flow destroy 0 rule 0
4133   Flow rule #0 destroyed
4134   testpmd>
4135
4136Querying flow rules
4137~~~~~~~~~~~~~~~~~~~
4138
4139``flow query`` queries a specific action of a flow rule having that
4140ability. Such actions collect information that can be reported using this
4141command. It is bound to ``rte_flow_query()``::
4142
4143   flow query {port_id} {rule_id} {action}
4144
4145If successful, it will display either the retrieved data for known actions
4146or the following message::
4147
4148   Cannot display result for action type [...] ([...])
4149
4150Otherwise, it will complain either that the rule does not exist or that some
4151error occurred::
4152
4153   Flow rule #[...] not found
4154
4155::
4156
4157   Caught error type [...] ([...]): [...]
4158
4159Currently only the ``count`` action is supported. This action reports the
4160number of packets that hit the flow rule and the total number of bytes. Its
4161output has the following format::
4162
4163   count:
4164    hits_set: [...] # whether "hits" contains a valid value
4165    bytes_set: [...] # whether "bytes" contains a valid value
4166    hits: [...] # number of packets
4167    bytes: [...] # number of bytes
4168
4169Querying counters for TCPv6 packets redirected to queue 6::
4170
4171   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4172      actions queue index 6 / count / end
4173   Flow rule #4 created
4174   testpmd> flow query 0 4 count
4175   count:
4176    hits_set: 1
4177    bytes_set: 0
4178    hits: 386446
4179    bytes: 0
4180   testpmd>
4181
4182Listing flow rules
4183~~~~~~~~~~~~~~~~~~
4184
4185``flow list`` lists existing flow rules sorted by priority and optionally
4186filtered by group identifiers::
4187
4188   flow list {port_id} [group {group_id}] [...]
4189
4190This command only fails with the following message if the device does not
4191exist::
4192
4193   Invalid port [...]
4194
4195Output consists of a header line followed by a short description of each
4196flow rule, one per line. There is no output at all when no flow rules are
4197configured on the device::
4198
4199   ID      Group   Prio    Attr    Rule
4200   [...]   [...]   [...]   [...]   [...]
4201
4202``Attr`` column flags:
4203
4204- ``i`` for ``ingress``.
4205- ``e`` for ``egress``.
4206
4207Creating several flow rules and listing them::
4208
4209   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4210      actions queue index 6 / end
4211   Flow rule #0 created
4212   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4213      actions queue index 2 / end
4214   Flow rule #1 created
4215   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4216      actions rss queues 6 7 8 end / end
4217   Flow rule #2 created
4218   testpmd> flow list 0
4219   ID      Group   Prio    Attr    Rule
4220   0       0       0       i-      ETH IPV4 => QUEUE
4221   1       0       0       i-      ETH IPV6 => QUEUE
4222   2       0       5       i-      ETH IPV4 UDP => RSS
4223   testpmd>
4224
4225Rules are sorted by priority (i.e. group ID first, then priority level)::
4226
4227   testpmd> flow list 1
4228   ID      Group   Prio    Attr    Rule
4229   0       0       0       i-      ETH => COUNT
4230   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4231   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4232   1       24      0       i-      ETH IPV4 UDP => QUEUE
4233   4       24      10      i-      ETH IPV4 TCP => DROP
4234   3       24      20      i-      ETH IPV4 => DROP
4235   2       24      42      i-      ETH IPV4 UDP => QUEUE
4236   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4237   testpmd>
4238
4239Output can be limited to specific groups::
4240
4241   testpmd> flow list 1 group 0 group 63
4242   ID      Group   Prio    Attr    Rule
4243   0       0       0       i-      ETH => COUNT
4244   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4245   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4246   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4247   testpmd>
4248
4249Toggling isolated mode
4250~~~~~~~~~~~~~~~~~~~~~~
4251
4252``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4253must only be injected from the defined flow rules; that no default traffic
4254is expected outside those rules and the driver is free to assign more
4255resources to handle them. It is bound to ``rte_flow_isolate()``::
4256
4257 flow isolate {port_id} {boolean}
4258
4259If successful, enabling or disabling isolated mode shows either::
4260
4261 Ingress traffic on port [...]
4262    is now restricted to the defined flow rules
4263
4264Or::
4265
4266 Ingress traffic on port [...]
4267    is not restricted anymore to the defined flow rules
4268
4269Otherwise, in case of error::
4270
4271   Caught error type [...] ([...]): [...]
4272
4273Mainly due to its side effects, PMDs supporting this mode may not have the
4274ability to toggle it more than once without reinitializing affected ports
4275first (e.g. by exiting testpmd).
4276
4277Enabling isolated mode::
4278
4279 testpmd> flow isolate 0 true
4280 Ingress traffic on port 0 is now restricted to the defined flow rules
4281 testpmd>
4282
4283Disabling isolated mode::
4284
4285 testpmd> flow isolate 0 false
4286 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4287 testpmd>
4288
4289Dumping HW internal information
4290~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4291
4292``flow dump`` dumps the hardware's internal representation information of
4293all flows. It is bound to ``rte_flow_dev_dump()``::
4294
4295   flow dump {port_id} {output_file}
4296
4297If successful, it will show::
4298
4299   Flow dump finished
4300
4301Otherwise, it will complain error occurred::
4302
4303   Caught error type [...] ([...]): [...]
4304
4305Listing and destroying aged flow rules
4306~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4307
4308``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4309and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4310
4311   flow aged {port_id} [destroy]
4312
4313Listing current aged flow rules::
4314
4315   testpmd> flow aged 0
4316   Port 0 total aged flows: 0
4317   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4318      actions age timeout 5 / queue index 0 /  end
4319   Flow rule #0 created
4320   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4321      actions age timeout 4 / queue index 0 /  end
4322   Flow rule #1 created
4323   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4324      actions age timeout 2 / queue index 0 /  end
4325   Flow rule #2 created
4326   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4327      actions age timeout 3 / queue index 0 /  end
4328   Flow rule #3 created
4329
4330
4331Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4332information, all the aged flows are sorted by the longest timeout time. For example, if
4333those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4334will be ID 3, ID 1, ID 0::
4335
4336   testpmd> flow aged 0

4362Creating indirect actions
4363~~~~~~~~~~~~~~~~~~~~~~~~~
4364
4365``flow indirect_action {port_id} create`` creates indirect action with optional
4366indirect action ID. It is bound to ``rte_flow_action_handle_create()``::
4367
4368   flow indirect_action {port_id} create [action_id {indirect_action_id}]
4369      [ingress] [egress] [transfer] action {action} / end
4370
4371If successful, it will show::
4372
4373   Indirect action #[...] created
4374
4375Otherwise, it will complain either that indirect action already exists or that
4376some error occurred::
4377
4378   Indirect action #[...] is already assigned, delete it first
4379
4380::
4381
4382   Caught error type [...] ([...]): [...]
4383
4384Create indirect rss action with id 100 to queues 1 and 2 on port 0::
4385
4386   testpmd> flow indirect_action 0 create action_id 100 \
4387      ingress action rss queues 1 2 end / end
4388
4389Create indirect rss action with id assigned by testpmd to queues 1 and 2 on
4390port 0::
4391
4392	testpmd> flow indirect_action 0 create action_id \
4393		ingress action rss queues 0 1 end / end
4394
4395Updating indirect actions
4396~~~~~~~~~~~~~~~~~~~~~~~~~
4397
4398``flow indirect_action {port_id} update`` updates configuration of the indirect
4399action from its indirect action ID (as returned by
4400``flow indirect_action {port_id} create``). It is bound to
4401``rte_flow_action_handle_update()``::
4402
4403   flow indirect_action {port_id} update {indirect_action_id}
4404      action {action} / end
4405
4406If successful, it will show::
4407
4408   Indirect action #[...] updated
4409
4410Otherwise, it will complain either that indirect action not found or that some
4411error occurred::
4412
4413   Failed to find indirect action #[...] on port [...]
4414
4415::
4416
4417   Caught error type [...] ([...]): [...]
4418
4419Update indirect rss action having id 100 on port 0 with rss to queues 0 and 3
4420(in create example above rss queues were 1 and 2)::
4421
4422   testpmd> flow indirect_action 0 update 100 action rss queues 0 3 end / end
4423
4424Destroying indirect actions
4425~~~~~~~~~~~~~~~~~~~~~~~~~~~
4426
4427``flow indirect_action {port_id} destroy`` destroys one or more indirect actions
4428from their indirect action IDs (as returned by
4429``flow indirect_action {port_id} create``). It is bound to
4430``rte_flow_action_handle_destroy()``::
4431
4432   flow indirect_action {port_id} destroy action_id {indirect_action_id} [...]
4433
4434If successful, it will show::
4435
4436   Indirect action #[...] destroyed
4437
4438It does not report anything for indirect action IDs that do not exist.
4439The usual error message is shown when a indirect action cannot be destroyed::
4440
4441   Caught error type [...] ([...]): [...]
4442
4443Destroy indirect actions having id 100 & 101::
4444
4445   testpmd> flow indirect_action 0 destroy action_id 100 action_id 101
4446
4447Query indirect actions
4448~~~~~~~~~~~~~~~~~~~~~~
4449
4450``flow indirect_action {port_id} query`` queries the indirect action from its
4451indirect action ID (as returned by ``flow indirect_action {port_id} create``).
4452It is bound to ``rte_flow_action_handle_query()``::
4453
4454  flow indirect_action {port_id} query {indirect_action_id}
4455
4456Currently only rss indirect action supported. If successful, it will show::
4457
4458   Indirect RSS action:
4459      refs:[...]
4460
4461Otherwise, it will complain either that indirect action not found or that some
4462error occurred::
4463
4464   Failed to find indirect action #[...] on port [...]
4465
4466::
4467
4468   Caught error type [...] ([...]): [...]
4469
4470Query indirect action having id 100::
4471
4472   testpmd> flow indirect_action 0 query 100
4473
4474Sample QinQ flow rules
4475~~~~~~~~~~~~~~~~~~~~~~
4476
4477Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4478
4479   testpmd> port stop 0
4480   testpmd> vlan set extend on 0
4481
4482The above command sets the inner and outer TPID's to 0x8100.
4483
4484To change the TPID's the following commands should be used::
4485
4486   testpmd> vlan set outer tpid 0x88A8 0
4487   testpmd> vlan set inner tpid 0x8100 0
4488   testpmd> port start 0
4489
4490Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4491
4492::
4493
4494   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4495       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4496   Flow rule #0 validated

4505
4506Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4507
4508::
4509
4510   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4511        vlan tci is 654 / end actions pf / queue index 0 / end

4522
4523Sample VXLAN flow rules
4524~~~~~~~~~~~~~~~~~~~~~~~
4525
4526Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4527filter on a port::
4528
4529  testpmd> rx_vxlan_port add 4789 0
4530
4531Create VXLAN rules on port 0 to steer traffic to PF queues.

4951            pattern eth / ipv4 / tcp / integrity value mask 8 value spec 8 / end
4952            actions jump group 1 / end
4953
4954Integrity rule that forwards invalid packets to application.
4955General packet integrity is matched with the ``packet_ok`` bit 0.

4959 testpmd> flow create 0 ingress pattern integrity value mask 1 value spec 0 / end actions queue index 0 / end
4960
4961Sample conntrack rules
4962~~~~~~~~~~~~~~~~~~~~~~
4963
4964Conntrack rules can be set by the following commands
4965
4966Need to construct the connection context with provided information.
4967In the first table, create a flow rule by using conntrack action and jump to
4968the next table. In the next table, create a rule to check the state.
4969
4970::
4971
4972 testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
4973        last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510
4974        last_seq 2632987379 last_ack 2532480967 last_end 2632987379
4975        last_index 0x8
4976 testpmd> set conntrack orig scale 7 fin 0 acked 1 unack_data 0
4977        sent_end 2632987379 reply_end 2633016339 max_win 28960
4978        max_ack 2632987379
4979 testpmd> set conntrack rply scale 7 fin 0 acked 1 unack_data 0
4980        sent_end 2532480967 reply_end 2532546247 max_win 65280
4981        max_ack 2532480967
4982 testpmd> flow indirect_action 0 create ingress action conntrack / end
4983 testpmd> flow create 0 group 3 ingress pattern eth / ipv4 / tcp / end actions indirect 0 / jump group 5 / end
4984 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
4985
4986Construct the conntrack again with only "is_orig" set to 0 (other fields are
4987ignored), then use "update" interface to update the direction. Create flow
4988rules like above for the peer port.
4989
4990::
4991
4992 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
4993
4994Sample meter with policy rules
4995~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4996
4997Meter with policy rules can be created by the following commands:
4998
4999Need to create policy first and actions are set for green/yellow/red colors.
5000Create meter with policy id. Create flow with meter id.
5001
5002Example for policy with meter color action. The purpose is to color the packet
5003to reflect the meter color result.
5004The meter policy action list: ``green -> green, yellow -> yellow, red -> red``.
5005
5006::
5007
5008   testpmd> add port meter profile srtcm_rfc2697 0 13 21504 2688 0 0
5009   testpmd> add port meter policy 0 1 g_actions color type green / end y_actions color type yellow / end
5010            r_actions color type red / end
5011   testpmd> create port meter 0 1 13 1 yes 0xffff 0 0
5012   testpmd> flow create 0 priority 0 ingress group 1 pattern eth / end actions meter mtr_id 1 / end
5013
5014BPF Functions
5015--------------
5016
5017The following sections show functions to load/unload eBPF based filters.
5018
5019bpf-load
5020~~~~~~~~
5021
5022Load an eBPF program as a callback for particular RX/TX queue::
5023
5024   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5025
5026The available load-flags are:
5027
5028* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5029
5030* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5031
5032* ``-``: none.
5033
5034.. note::
5035
5036   You'll need clang v3.7 or above to build bpf program you'd like to load
5037
5038For example:
5039
5040.. code-block:: console
5041
5042   cd examples/bpf
5043   clang -O2 -target bpf -c t1.c
5044
5045Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5046
5047.. code-block:: console
5048
5049   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5050
5051To load (not JITed) t1.o at TX queue 0, port 0:
5052
5053.. code-block:: console
5054
5055   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5056
5057bpf-unload
5058~~~~~~~~~~
5059
5060Unload previously loaded eBPF program for particular RX/TX queue::
5061
5062   testpmd> bpf-unload rx|tx (portid) (queueid)
5063
5064For example to unload BPF filter from TX queue 0, port 0:
5065
5066.. code-block:: console
5067
5068   testpmd> bpf-unload tx 0 0
5069
