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.

272
273show config
274~~~~~~~~~~~
275
276Displays the configuration of the application.
277The configuration comes from the command-line, the runtime or the application defaults::

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

1955rte_flow_action_raw_encap::
1956
1957 set raw_encap {index} {item} [/ {item} [...]] / end_set
1958
1959There are multiple global buffers for ``raw_encap``, this command will set one
1960internal buffer index by ``{index}``.
1961If there is no ``{index}`` specified::
1962
1963 set raw_encap {item} [/ {item} [...]] / end_set
1964
1965the default index ``0`` is used.

2023Port Functions
2024--------------
2025
2026The following sections show functions for configuring ports.
2027
2028.. note::
2029
2030   Port configuration changes only become active when forwarding is started/restarted.
2031
2032port attach
2033~~~~~~~~~~~
2034
2035Attach a port specified by pci address or virtual device args::
2036
2037   testpmd> port attach (identifier)
2038
2039To attach a new pci device, the device should be recognized by kernel first.
2040Then it should be moved under DPDK management.
2041Finally the port can be attached to testpmd.
2042
2043For example, to move a pci device using ixgbe under DPDK management:
2044
2045.. code-block:: console
2046
2047   # Check the status of the available devices.
2048   ./usertools/dpdk-devbind.py --status
2049
2050   Network devices using DPDK-compatible driver
2051   ============================================
2052   <none>
2053
2054   Network devices using kernel driver
2055   ===================================
2056   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2057
2058
2059   # Bind the device to igb_uio.
2060   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2061
2062
2063   # Recheck the status of the devices.
2064   ./usertools/dpdk-devbind.py --status
2065   Network devices using DPDK-compatible driver
2066   ============================================
2067   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2068
2069To attach a port created by virtual device, above steps are not needed.
2070
2071For example, to attach a port whose pci address is 0000:0a:00.0.
2072
2073.. code-block:: console
2074
2075   testpmd> port attach 0000:0a:00.0
2076   Attaching a new port...
2077   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2078   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
2079   EAL:   PCI memory mapped at 0x7f83bfa00000
2080   EAL:   PCI memory mapped at 0x7f83bfa80000
2081   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2082   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2083   Port 0 is attached. Now total ports is 1
2084   Done
2085
2086For example, to attach a port created by pcap PMD.
2087
2088.. code-block:: console
2089
2090   testpmd> port attach net_pcap0
2091   Attaching a new port...
2092   PMD: Initializing pmd_pcap for net_pcap0
2093   PMD: Creating pcap-backed ethdev on numa socket 0
2094   Port 0 is attached. Now total ports is 1
2095   Done
2096
2097In this case, identifier is ``net_pcap0``.
2098This identifier format is the same as ``--vdev`` format of DPDK applications.
2099
2100For example, to re-attach a bonded port which has been previously detached,
2101the mode and slave parameters must be given.
2102
2103.. code-block:: console
2104
2105   testpmd> port attach net_bond_0,mode=0,slave=1
2106   Attaching a new port...
2107   EAL: Initializing pmd_bond for net_bond_0
2108   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2109   Port 0 is attached. Now total ports is 1
2110   Done
2111
2112
2113port detach
2114~~~~~~~~~~~
2115
2116Detach a specific port::
2117
2118   testpmd> port detach (port_id)
2119
2120Before detaching a port, the port should be stopped and closed.
2121
2122For example, to detach a pci device port 0.
2123
2124.. code-block:: console
2125
2126   testpmd> port stop 0
2127   Stopping ports...
2128   Done
2129   testpmd> port close 0
2130   Closing ports...
2131   Done
2132
2133   testpmd> port detach 0
2134   Detaching a port...
2135   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2136   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
2137   EAL:   PCI memory unmapped at 0x7f83bfa00000
2138   EAL:   PCI memory unmapped at 0x7f83bfa80000
2139   Done
2140
2141
2142For example, to detach a virtual device port 0.
2143
2144.. code-block:: console
2145
2146   testpmd> port stop 0
2147   Stopping ports...
2148   Done
2149   testpmd> port close 0
2150   Closing ports...
2151   Done
2152
2153   testpmd> port detach 0
2154   Detaching a port...
2155   PMD: Closing pcap ethdev on numa socket 0
2156   Port 'net_pcap0' is detached. Now total ports is 0
2157   Done
2158
2159To remove a pci device completely from the system, first detach the port from testpmd.
2160Then the device should be moved under kernel management.
2161Finally the device can be removed using kernel pci hotplug functionality.
2162
2163For example, to move a pci device under kernel management:
2164
2165.. code-block:: console
2166
2167   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2168
2169   ./usertools/dpdk-devbind.py --status

2254Set number of queues/descriptors for rxq, txq, rxd and txd::
2255
2256   testpmd> port config all (rxq|txq|rxd|txd) (value)
2257
2258This is equivalent to the ``--rxq``, ``--txq``, ``--rxd`` and ``--txd`` command-line options.

2284
2285Packet dropping when no receive buffers available is off by default.
2286
2287The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2288
2289port config - RSS
2290~~~~~~~~~~~~~~~~~
2291
2292Set the RSS (Receive Side Scaling) mode on or off::

2317
2318The traffic class should be 4 or 8.
2319
2320port config - Burst
2321~~~~~~~~~~~~~~~~~~~
2322
2323Set the number of packets per burst::
2324
2325   testpmd> port config all burst (value)

2439Device Functions
2440----------------
2441
2442The following sections show functions for device operations.
2443
2444device detach
2445~~~~~~~~~~~~~
2446
2447Detach a device specified by pci address or virtual device args::
2448
2449   testpmd> device detach (identifier)
2450
2451Before detaching a device associated with ports, the ports should be stopped and closed.
2452
2453For example, to detach a pci device whose address is 0002:03:00.0.
2454
2455.. code-block:: console
2456
2457    testpmd> device detach 0002:03:00.0
2458    Removing a device...
2459    Port 1 is now closed
2460    EAL: Releasing pci mapped resource for 0002:03:00.0
2461    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2462    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2463    Device 0002:03:00.0 is detached
2464    Now total ports is 1
2465
2466For example, to detach a port created by pcap PMD.
2467
2468.. code-block:: console
2469
2470    testpmd> device detach net_pcap0
2471    Removing a device...
2472    Port 0 is now closed
2473    Device net_pcap0 is detached
2474    Now total ports is 0
2475    Done
2476
2477In this case, identifier is ``net_pcap0``.
2478This identifier format is the same as ``--vdev`` format of DPDK applications.
2479
2480Link Bonding Functions

2503   testpmd> add bonding slave (slave id) (port id)
2504
2505For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2506
2507   testpmd> add bonding slave 6 10
2508
2509
2510remove bonding slave
2511~~~~~~~~~~~~~~~~~~~~
2512
2513Removes an Ethernet slave device from a Link Bonding device::
2514
2515   testpmd> remove bonding slave (slave id) (port id)
2516
2517For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::

2561For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2562
2563   testpmd> set bonding balance_xmit_policy 10 l34
2564
2565
2566set bonding mon_period
2567~~~~~~~~~~~~~~~~~~~~~~

2570
2571This adds support for PMD slave devices which do not support link status interrupts.
2572When the mon_period is set to a value greater than 0 then all PMD's which do not support
2573link status ISR will be queried every polling interval to check if their link status has changed::
2574
2575   testpmd> set bonding mon_period (port_id) (value)
2576
2577For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

2603
2604   testpmd> show bonding config (port id)
2605
2606For example,
2607to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
2608in balance mode with a transmission policy of layer 2+3::
2609
2610   testpmd> show bonding config 9
2611        Bonding mode: 2
2612        Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23

3227Filter Functions
3228----------------
3229
3230This section details the available filter functions that are available.
3231
3232Note these functions interface the deprecated legacy filtering framework,
3233superseded by *rte_flow*. See `Flow rules management`_.
3234
3235.. _testpmd_flow_director:
3236
3237flow_director_mask
3238~~~~~~~~~~~~~~~~~~
3239
3240Set flow director's input masks::
3241
3242   flow_director_mask (port_id) mode IP vlan (vlan_value) \
3243                      src_mask (ipv4_src) (ipv6_src) (src_port) \
3244                      dst_mask (ipv4_dst) (ipv6_dst) (dst_port)
3245
3246   flow_director_mask (port_id) mode MAC-VLAN vlan (vlan_value)
3247
3248   flow_director_mask (port_id) mode Tunnel vlan (vlan_value) \

3250                      tunnel-id (tunnel_id_value)
3251
3252Example, to set flow director mask on port 0::

3275Flow rules management
3276---------------------
3277
3278Control of the generic flow API (*rte_flow*) is fully exposed through the
3279``flow`` command (validation, creation, destruction, queries and operation
3280modes).
3281
3282Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3283features simultaneously may cause undefined side-effects and is therefore
3284not recommended.
3285
3286``flow`` syntax
3287~~~~~~~~~~~~~~~
3288
3289Because the ``flow`` command uses dynamic tokens to handle the large number
3290of possible flow rules combinations, its behavior differs slightly from
3291other commands, in particular:
3292
3293- Pressing *?* or the *<tab>* key displays contextual help for the current
3294  token, not that of the entire command.
3295
3296- Optional and repeated parameters are supported (provided they are listed
3297  in the contextual help).
3298
3299The first parameter stands for the operation mode. Possible operations and
3300their general syntax are described below. They are covered in detail in the
3301following sections.
3302
3303- Check whether a flow rule can be created::
3304
3305   flow validate {port_id}
3306       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3307       pattern {item} [/ {item} [...]] / end
3308       actions {action} [/ {action} [...]] / end
3309
3310- Create a flow rule::
3311
3312   flow create {port_id}
3313       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3314       pattern {item} [/ {item} [...]] / end
3315       actions {action} [/ {action} [...]] / end
3316
3317- Destroy specific flow rules::
3318
3319   flow destroy {port_id} rule {rule_id} [...]
3320
3321- Destroy all flow rules::
3322
3323   flow flush {port_id}
3324
3325- Query an existing flow rule::
3326
3327   flow query {port_id} {rule_id} {action}
3328
3329- List existing flow rules sorted by priority, filtered by group
3330  identifiers::
3331
3332   flow list {port_id} [group {group_id}] [...]
3333
3334- Restrict ingress traffic to the defined flow rules::
3335
3336   flow isolate {port_id} {boolean}
3337
3338- Dump internal representation information of all flows in hardware::
3339
3340   flow dump {port_id} all {output_file}
3341
3342  for one flow::
3343
3344   flow dump {port_id} rule {rule_id} {output_file}
3345
3346- List and destroy aged flow rules::
3347
3348   flow aged {port_id} [destroy]
3349
3350- Tunnel offload - create a tunnel stub::
3351
3352   flow tunnel create {port_id} type {tunnel_type}
3353
3354- Tunnel offload - destroy a tunnel stub::
3355
3356   flow tunnel destroy {port_id} id {tunnel_id}
3357
3358- Tunnel offload - list port tunnel stubs::
3359
3360   flow tunnel list {port_id}
3361
3362Creating a tunnel stub for offload
3363~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3364
3365``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3366
3367   flow tunnel create {port_id} type {tunnel_type}
3368
3369If successful, it will return a tunnel stub ID usable with other commands::
3370
3371   port [...]: flow tunnel #[...] type [...]
3372
3373Tunnel stub ID is relative to a port.
3374
3375Destroying tunnel offload stub
3376~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3377
3378``flow tunnel destroy`` destroy port tunnel stub::
3379
3380   flow tunnel destroy {port_id} id {tunnel_id}
3381
3382Listing tunnel offload stubs
3383~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3384
3385``flow tunnel list`` list port tunnel offload stubs::
3386
3387   flow tunnel list {port_id}
3388
3389Validating flow rules
3390~~~~~~~~~~~~~~~~~~~~~
3391
3392``flow validate`` reports whether a flow rule would be accepted by the
3393underlying device in its current state but stops short of creating it. It is
3394bound to ``rte_flow_validate()``::
3395
3396   flow validate {port_id}
3397      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3398      pattern {item} [/ {item} [...]] / end
3399      actions {action} [/ {action} [...]] / end
3400
3401If successful, it will show::
3402
3403   Flow rule validated
3404
3405Otherwise it will show an error message of the form::
3406
3407   Caught error type [...] ([...]): [...]
3408
3409This command uses the same parameters as ``flow create``, their format is
3410described in `Creating flow rules`_.
3411
3412Check whether redirecting any Ethernet packet received on port 0 to RX queue
3413index 6 is supported::
3414
3415   testpmd> flow validate 0 ingress pattern eth / end
3416      actions queue index 6 / end
3417   Flow rule validated
3418   testpmd>
3419
3420Port 0 does not support TCPv6 rules::
3421
3422   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3423      actions drop / end
3424   Caught error type 9 (specific pattern item): Invalid argument
3425   testpmd>
3426
3427Creating flow rules
3428~~~~~~~~~~~~~~~~~~~
3429
3430``flow create`` validates and creates the specified flow rule. It is bound
3431to ``rte_flow_create()``::
3432
3433   flow create {port_id}
3434      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3435      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3436      pattern {item} [/ {item} [...]] / end
3437      actions {action} [/ {action} [...]] / end
3438
3439If successful, it will return a flow rule ID usable with other commands::
3440
3441   Flow rule #[...] created
3442
3443Otherwise it will show an error message of the form::
3444
3445   Caught error type [...] ([...]): [...]
3446
3447Parameters describe in the following order:
3448
3449- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3450- Tunnel offload specification (tunnel_set, tunnel_match)
3451- A matching pattern, starting with the *pattern* token and terminated by an
3452  *end* pattern item.
3453- Actions, starting with the *actions* token and terminated by an *end*
3454  action.
3455
3456These translate directly to *rte_flow* objects provided as-is to the
3457underlying functions.
3458
3459The shortest valid definition only comprises mandatory tokens::
3460
3461   testpmd> flow create 0 pattern end actions end
3462
3463Note that PMDs may refuse rules that essentially do nothing such as this
3464one.
3465
3466**All unspecified object values are automatically initialized to 0.**
3467
3468Attributes
3469^^^^^^^^^^
3470
3471These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3472specified before the ``pattern`` token.
3473
3474- ``group {group id}``: priority group.
3475- ``priority {level}``: priority level within group.
3476- ``ingress``: rule applies to ingress traffic.
3477- ``egress``: rule applies to egress traffic.
3478- ``transfer``: apply rule directly to endpoints found in pattern.
3479
3480Each instance of an attribute specified several times overrides the previous
3481value as shown below (group 4 is used)::
3482
3483   testpmd> flow create 0 group 42 group 24 group 4 [...]
3484
3485Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3486
3487While not specifying a direction is an error, some rules may allow both
3488simultaneously.
3489
3490Most rules affect RX therefore contain the ``ingress`` token::
3491
3492   testpmd> flow create 0 ingress pattern [...]
3493
3494Tunnel offload
3495^^^^^^^^^^^^^^
3496
3497Indicate tunnel offload rule type
3498
3499- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3500- ``tunnel_match {tunnel_id}``:  mark rule as tunel offload match type.
3501
3502Matching pattern
3503^^^^^^^^^^^^^^^^
3504
3505A matching pattern starts after the ``pattern`` token. It is made of pattern
3506items and is terminated by a mandatory ``end`` item.
3507
3508Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3509rte_flow_item_type``).
3510
3511The ``/`` token is used as a separator between pattern items as shown
3512below::
3513
3514   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3515
3516Note that protocol items like these must be stacked from lowest to highest
3517layer to make sense. For instance, the following rule is either invalid or
3518unlikely to match any packet::
3519
3520   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3521
3522More information on these restrictions can be found in the *rte_flow*
3523documentation.
3524
3525Several items support additional specification structures, for example
3526``ipv4`` allows specifying source and destination addresses as follows::
3527
3528   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3529      dst is 10.2.0.0 / end [...]
3530
3531This rule matches all IPv4 traffic with the specified properties.
3532
3533In this example, ``src`` and ``dst`` are field names of the underlying
3534``struct rte_flow_item_ipv4`` object. All item properties can be specified
3535in a similar fashion.
3536
3537The ``is`` token means that the subsequent value must be matched exactly,
3538and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3539accordingly. Possible assignment tokens are:
3540
3541- ``is``: match value perfectly (with full bit-mask).
3542- ``spec``: match value according to configured bit-mask.
3543- ``last``: specify upper bound to establish a range.
3544- ``mask``: specify bit-mask with relevant bits set to one.
3545- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3546
3547These yield identical results::
3548
3549   ipv4 src is 10.1.1.1
3550
3551::
3552
3553   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3554
3555::
3556
3557   ipv4 src spec 10.1.1.1 src prefix 32
3558
3559::
3560
3561   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3562
3563::
3564
3565   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3566
3567Inclusive ranges can be defined with ``last``::
3568
3569   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3570
3571Note that ``mask`` affects both ``spec`` and ``last``::
3572
3573   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3574      # matches 10.1.0.0 to 10.2.255.255
3575
3576Properties can be modified multiple times::
3577
3578   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3579
3580::
3581
3582   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3583

3804
3805Actions list
3806^^^^^^^^^^^^
3807
3808A list of actions starts after the ``actions`` token in the same fashion as
3809`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3810terminated by a mandatory ``end`` action.
3811
3812Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3813rte_flow_action_type``).
3814
3815Dropping all incoming UDPv4 packets can be expressed as follows::
3816
3817   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3818      actions drop / end
3819
3820Several actions have configurable properties which must be specified when
3821there is no valid default value. For example, ``queue`` requires a target
3822queue index.
3823
3824This rule redirects incoming UDPv4 traffic to queue index 6::
3825
3826   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3827      actions queue index 6 / end
3828
3829While this one could be rejected by PMDs (unspecified queue index)::
3830
3831   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3832      actions queue / end
3833
3834As defined by *rte_flow*, the list is not ordered, all actions of a given
3835rule are performed simultaneously. These are equivalent::
3836
3837   queue index 6 / void / mark id 42 / end
3838
3839::
3840
3841   void / mark id 42 / queue index 6 / end
3842
3843All actions in a list should have different types, otherwise only the last
3844action of a given type is taken into account::
3845
3846   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3847
3848::
3849
3850   drop / drop / drop / end # drop is performed only once
3851
3852::
3853
3854   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3855
3856Considering they are performed simultaneously, opposite and overlapping
3857actions can sometimes be combined when the end result is unambiguous::
3858
3859   drop / queue index 6 / end # drop has no effect
3860
3861::
3862
3863   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3864
3865::
3866
3867   drop / passthru / end # drop has no effect
3868
3869Note that PMDs may still refuse such combinations.

4076Destroying flow rules
4077~~~~~~~~~~~~~~~~~~~~~
4078
4079``flow destroy`` destroys one or more rules from their rule ID (as returned
4080by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4081times as necessary::
4082
4083   flow destroy {port_id} rule {rule_id} [...]
4084
4085If successful, it will show::
4086
4087   Flow rule #[...] destroyed
4088
4089It does not report anything for rule IDs that do not exist. The usual error
4090message is shown when a rule cannot be destroyed::
4091
4092   Caught error type [...] ([...]): [...]
4093
4094``flow flush`` destroys all rules on a device and does not take extra
4095arguments. It is bound to ``rte_flow_flush()``::
4096
4097   flow flush {port_id}
4098
4099Any errors are reported as above.
4100
4101Creating several rules and destroying them::
4102
4103   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4104      actions queue index 2 / end
4105   Flow rule #0 created
4106   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4107      actions queue index 3 / end
4108   Flow rule #1 created
4109   testpmd> flow destroy 0 rule 0 rule 1
4110   Flow rule #1 destroyed
4111   Flow rule #0 destroyed
4112   testpmd>
4113
4114The same result can be achieved using ``flow flush``::
4115
4116   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4117      actions queue index 2 / end
4118   Flow rule #0 created
4119   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4120      actions queue index 3 / end
4121   Flow rule #1 created
4122   testpmd> flow flush 0
4123   testpmd>
4124
4125Non-existent rule IDs are ignored::
4126
4127   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4128      actions queue index 2 / end
4129   Flow rule #0 created
4130   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4131      actions queue index 3 / end
4132   Flow rule #1 created
4133   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4134   testpmd>
4135   testpmd> flow destroy 0 rule 0
4136   Flow rule #0 destroyed
4137   testpmd>
4138
4139Querying flow rules
4140~~~~~~~~~~~~~~~~~~~
4141
4142``flow query`` queries a specific action of a flow rule having that
4143ability. Such actions collect information that can be reported using this
4144command. It is bound to ``rte_flow_query()``::
4145
4146   flow query {port_id} {rule_id} {action}
4147
4148If successful, it will display either the retrieved data for known actions
4149or the following message::
4150
4151   Cannot display result for action type [...] ([...])
4152
4153Otherwise, it will complain either that the rule does not exist or that some
4154error occurred::
4155
4156   Flow rule #[...] not found
4157
4158::
4159
4160   Caught error type [...] ([...]): [...]
4161
4162Currently only the ``count`` action is supported. This action reports the
4163number of packets that hit the flow rule and the total number of bytes. Its
4164output has the following format::
4165
4166   count:
4167    hits_set: [...] # whether "hits" contains a valid value
4168    bytes_set: [...] # whether "bytes" contains a valid value
4169    hits: [...] # number of packets
4170    bytes: [...] # number of bytes
4171
4172Querying counters for TCPv6 packets redirected to queue 6::
4173
4174   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4175      actions queue index 6 / count / end
4176   Flow rule #4 created
4177   testpmd> flow query 0 4 count
4178   count:
4179    hits_set: 1
4180    bytes_set: 0
4181    hits: 386446
4182    bytes: 0
4183   testpmd>
4184
4185Listing flow rules
4186~~~~~~~~~~~~~~~~~~
4187
4188``flow list`` lists existing flow rules sorted by priority and optionally
4189filtered by group identifiers::
4190
4191   flow list {port_id} [group {group_id}] [...]
4192
4193This command only fails with the following message if the device does not
4194exist::
4195
4196   Invalid port [...]
4197
4198Output consists of a header line followed by a short description of each
4199flow rule, one per line. There is no output at all when no flow rules are
4200configured on the device::
4201
4202   ID      Group   Prio    Attr    Rule
4203   [...]   [...]   [...]   [...]   [...]
4204
4205``Attr`` column flags:
4206
4207- ``i`` for ``ingress``.
4208- ``e`` for ``egress``.
4209
4210Creating several flow rules and listing them::
4211
4212   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4213      actions queue index 6 / end
4214   Flow rule #0 created
4215   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4216      actions queue index 2 / end
4217   Flow rule #1 created
4218   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4219      actions rss queues 6 7 8 end / end
4220   Flow rule #2 created
4221   testpmd> flow list 0
4222   ID      Group   Prio    Attr    Rule
4223   0       0       0       i-      ETH IPV4 => QUEUE
4224   1       0       0       i-      ETH IPV6 => QUEUE
4225   2       0       5       i-      ETH IPV4 UDP => RSS
4226   testpmd>
4227
4228Rules are sorted by priority (i.e. group ID first, then priority level)::
4229
4230   testpmd> flow list 1
4231   ID      Group   Prio    Attr    Rule
4232   0       0       0       i-      ETH => COUNT
4233   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4234   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4235   1       24      0       i-      ETH IPV4 UDP => QUEUE
4236   4       24      10      i-      ETH IPV4 TCP => DROP
4237   3       24      20      i-      ETH IPV4 => DROP
4238   2       24      42      i-      ETH IPV4 UDP => QUEUE
4239   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4240   testpmd>
4241
4242Output can be limited to specific groups::
4243
4244   testpmd> flow list 1 group 0 group 63
4245   ID      Group   Prio    Attr    Rule
4246   0       0       0       i-      ETH => COUNT
4247   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4248   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4249   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4250   testpmd>
4251
4252Toggling isolated mode
4253~~~~~~~~~~~~~~~~~~~~~~
4254
4255``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4256must only be injected from the defined flow rules; that no default traffic
4257is expected outside those rules and the driver is free to assign more
4258resources to handle them. It is bound to ``rte_flow_isolate()``::
4259
4260 flow isolate {port_id} {boolean}
4261
4262If successful, enabling or disabling isolated mode shows either::
4263
4264 Ingress traffic on port [...]
4265    is now restricted to the defined flow rules
4266
4267Or::
4268
4269 Ingress traffic on port [...]
4270    is not restricted anymore to the defined flow rules
4271
4272Otherwise, in case of error::
4273
4274   Caught error type [...] ([...]): [...]
4275
4276Mainly due to its side effects, PMDs supporting this mode may not have the
4277ability to toggle it more than once without reinitializing affected ports
4278first (e.g. by exiting testpmd).
4279
4280Enabling isolated mode::
4281
4282 testpmd> flow isolate 0 true
4283 Ingress traffic on port 0 is now restricted to the defined flow rules
4284 testpmd>
4285
4286Disabling isolated mode::
4287
4288 testpmd> flow isolate 0 false
4289 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4290 testpmd>
4291
4292Dumping HW internal information
4293~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4294
4295``flow dump`` dumps the hardware's internal representation information of
4296all flows. It is bound to ``rte_flow_dev_dump()``::
4297
4298   flow dump {port_id} {output_file}
4299
4300If successful, it will show::
4301
4302   Flow dump finished
4303
4304Otherwise, it will complain error occurred::
4305
4306   Caught error type [...] ([...]): [...]
4307
4308Listing and destroying aged flow rules
4309~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4310
4311``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4312and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4313
4314   flow aged {port_id} [destroy]
4315
4316Listing current aged flow rules::
4317
4318   testpmd> flow aged 0
4319   Port 0 total aged flows: 0
4320   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4321      actions age timeout 5 / queue index 0 /  end
4322   Flow rule #0 created
4323   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4324      actions age timeout 4 / queue index 0 /  end
4325   Flow rule #1 created
4326   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4327      actions age timeout 2 / queue index 0 /  end
4328   Flow rule #2 created
4329   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4330      actions age timeout 3 / queue index 0 /  end
4331   Flow rule #3 created
4332
4333
4334Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4335information, all the aged flows are sorted by the longest timeout time. For example, if
4336those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4337will be ID 3, ID 1, ID 0::
4338
4339   testpmd> flow aged 0
4340   Port 0 total aged flows: 4
4341   ID      Group   Prio    Attr

4345   0       0       0       i--
4346
4347If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.

4365Creating indirect actions
4366~~~~~~~~~~~~~~~~~~~~~~~~~
4367
4368``flow indirect_action {port_id} create`` creates indirect action with optional
4369indirect action ID. It is bound to ``rte_flow_action_handle_create()``::
4370
4371   flow indirect_action {port_id} create [action_id {indirect_action_id}]
4372      [ingress] [egress] [transfer] action {action} / end
4373
4374If successful, it will show::
4375
4376   Indirect action #[...] created
4377
4378Otherwise, it will complain either that indirect action already exists or that
4379some error occurred::
4380
4381   Indirect action #[...] is already assigned, delete it first
4382
4383::
4384
4385   Caught error type [...] ([...]): [...]
4386
4387Create indirect rss action with id 100 to queues 1 and 2 on port 0::
4388
4389   testpmd> flow indirect_action 0 create action_id 100 \
4390      ingress action rss queues 1 2 end / end
4391
4392Create indirect rss action with id assigned by testpmd to queues 1 and 2 on
4393port 0::
4394
4395	testpmd> flow indirect_action 0 create action_id \
4396		ingress action rss queues 0 1 end / end
4397
4398Updating indirect actions
4399~~~~~~~~~~~~~~~~~~~~~~~~~
4400
4401``flow indirect_action {port_id} update`` updates configuration of the indirect
4402action from its indirect action ID (as returned by
4403``flow indirect_action {port_id} create``). It is bound to
4404``rte_flow_action_handle_update()``::
4405
4406   flow indirect_action {port_id} update {indirect_action_id}
4407      action {action} / end
4408
4409If successful, it will show::
4410
4411   Indirect action #[...] updated
4412
4413Otherwise, it will complain either that indirect action not found or that some
4414error occurred::
4415
4416   Failed to find indirect action #[...] on port [...]
4417
4418::
4419
4420   Caught error type [...] ([...]): [...]
4421
4422Update indirect rss action having id 100 on port 0 with rss to queues 0 and 3
4423(in create example above rss queues were 1 and 2)::
4424
4425   testpmd> flow indirect_action 0 update 100 action rss queues 0 3 end / end
4426
4427Destroying indirect actions
4428~~~~~~~~~~~~~~~~~~~~~~~~~~~
4429
4430``flow indirect_action {port_id} destroy`` destroys one or more indirect actions
4431from their indirect action IDs (as returned by
4432``flow indirect_action {port_id} create``). It is bound to
4433``rte_flow_action_handle_destroy()``::
4434
4435   flow indirect_action {port_id} destroy action_id {indirect_action_id} [...]
4436
4437If successful, it will show::
4438
4439   Indirect action #[...] destroyed
4440
4441It does not report anything for indirect action IDs that do not exist.
4442The usual error message is shown when a indirect action cannot be destroyed::
4443
4444   Caught error type [...] ([...]): [...]
4445
4446Destroy indirect actions having id 100 & 101::
4447
4448   testpmd> flow indirect_action 0 destroy action_id 100 action_id 101
4449
4450Query indirect actions
4451~~~~~~~~~~~~~~~~~~~~~~
4452
4453``flow indirect_action {port_id} query`` queries the indirect action from its
4454indirect action ID (as returned by ``flow indirect_action {port_id} create``).
4455It is bound to ``rte_flow_action_handle_query()``::
4456
4457  flow indirect_action {port_id} query {indirect_action_id}
4458
4459Currently only rss indirect action supported. If successful, it will show::
4460
4461   Indirect RSS action:
4462      refs:[...]
4463
4464Otherwise, it will complain either that indirect action not found or that some
4465error occurred::
4466
4467   Failed to find indirect action #[...] on port [...]
4468
4469::
4470
4471   Caught error type [...] ([...]): [...]
4472
4473Query indirect action having id 100::
4474
4475   testpmd> flow indirect_action 0 query 100
4476
4477Sample QinQ flow rules
4478~~~~~~~~~~~~~~~~~~~~~~
4479
4480Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4481
4482   testpmd> port stop 0
4483   testpmd> vlan set extend on 0
4484
4485The above command sets the inner and outer TPID's to 0x8100.
4486
4487To change the TPID's the following commands should be used::
4488
4489   testpmd> vlan set outer tpid 0x88A8 0
4490   testpmd> vlan set inner tpid 0x8100 0
4491   testpmd> port start 0
4492
4493Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4494
4495::
4496
4497   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4498       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4499   Flow rule #0 validated
4500
4501   testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /

4507   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
4508
4509Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4510
4511::
4512
4513   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4514        vlan tci is 654 / end actions pf / queue index 0 / end
4515   Flow rule #1 validated

4525
4526Sample VXLAN flow rules
4527~~~~~~~~~~~~~~~~~~~~~~~
4528
4529Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4530filter on a port::
4531
4532  testpmd> rx_vxlan_port add 4789 0
4533
4534Create VXLAN rules on port 0 to steer traffic to PF queues.

4949TCP packet integrity is matched with the ``l4_ok`` bit 3.
4950
4951::
4952
4953 testpmd> flow create 0 ingress
4954            pattern eth / ipv4 / tcp / integrity value mask 8 value spec 8 / end
4955            actions jump group 1 / end
4956
4957Integrity rule that forwards invalid packets to application.
4958General packet integrity is matched with the ``packet_ok`` bit 0.
4959
4960::
4961
4962 testpmd> flow create 0 ingress pattern integrity value mask 1 value spec 0 / end actions queue index 0 / end
4963
4964Sample conntrack rules
4965~~~~~~~~~~~~~~~~~~~~~~
4966
4967Conntrack rules can be set by the following commands
4968
4969Need to construct the connection context with provided information.
4970In the first table, create a flow rule by using conntrack action and jump to
4971the next table. In the next table, create a rule to check the state.
4972
4973::
4974
4975 testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
4976        last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510
4977        last_seq 2632987379 last_ack 2532480967 last_end 2632987379
4978        last_index 0x8
4979 testpmd> set conntrack orig scale 7 fin 0 acked 1 unack_data 0
4980        sent_end 2632987379 reply_end 2633016339 max_win 28960
4981        max_ack 2632987379
4982 testpmd> set conntrack rply scale 7 fin 0 acked 1 unack_data 0
4983        sent_end 2532480967 reply_end 2532546247 max_win 65280
4984        max_ack 2532480967
4985 testpmd> flow indirect_action 0 create ingress action conntrack / end
4986 testpmd> flow create 0 group 3 ingress pattern eth / ipv4 / tcp / end actions indirect 0 / jump group 5 / end
4987 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
4988
4989Construct the conntrack again with only "is_orig" set to 0 (other fields are
4990ignored), then use "update" interface to update the direction. Create flow
4991rules like above for the peer port.
4992
4993::
4994
4995 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
4996
4997BPF Functions
4998--------------
4999
5000The following sections show functions to load/unload eBPF based filters.
5001
5002bpf-load
5003~~~~~~~~
5004
5005Load an eBPF program as a callback for particular RX/TX queue::
5006
5007   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5008
5009The available load-flags are:
5010
5011* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5012
5013* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5014
5015* ``-``: none.
5016
5017.. note::
5018
5019   You'll need clang v3.7 or above to build bpf program you'd like to load
5020
5021For example:
5022
5023.. code-block:: console
5024
5025   cd examples/bpf
5026   clang -O2 -target bpf -c t1.c
5027
5028Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5029
5030.. code-block:: console
5031
5032   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5033
5034To load (not JITed) t1.o at TX queue 0, port 0:
5035
5036.. code-block:: console
5037
5038   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5039
5040bpf-unload
5041~~~~~~~~~~
5042
5043Unload previously loaded eBPF program for particular RX/TX queue::
5044
5045   testpmd> bpf-unload rx|tx (portid) (queueid)
5046
5047For example to unload BPF filter from TX queue 0, port 0:
5048
5049.. code-block:: console
5050
5051   testpmd> bpf-unload tx 0 0
5052
