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       Help is available for the following sections:
53
54           help control                    : Start and stop forwarding.
55           help display                    : Displaying port, stats and config information.

64Command File Functions
65----------------------
66
67To facilitate loading large number of commands or to avoid cutting and pasting where not
68practical or possible testpmd supports alternative methods for executing commands.
69
70* If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
71  will execute all CLI commands contained within the file immediately before
72  starting packet forwarding or entering interactive mode.
73
74.. code-block:: console
75
76   ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

95
96
97* At run-time additional commands can be loaded in bulk by invoking the ``load FILENAME``
98  command.
99
100.. code-block:: console
101
102   testpmd> load /home/ubuntu/flow-create-commands.txt
103   Flow rule #0 created

109   Read all CLI commands from /home/ubuntu/flow-create-commands.txt
110   testpmd>
111
112
113In all cases output from any included command will be displayed as standard output.
114Execution will continue until the end of the file is reached regardless of
115whether any errors occur.  The end user must examine the output to determine if
116any failures occurred.

308   nb forwarding cores=2 - nb forwarding ports=1
309   RX queues=1 - RX desc=128 - RX free threshold=0
310   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
311   TX queues=1 - TX desc=512 - TX free threshold=0
312   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
313   TX RS bit threshold=0 - TXQ flags=0x0
314
315set fwd
316~~~~~~~
317
318Set the packet forwarding mode::
319
320   testpmd> set fwd (io|mac|macswap|flowgen| \
321                     rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq) (""|retry)
322
323``retry`` can be specified for forwarding engines except ``rx_only``.
324
325The available information categories are:
326
327* ``io``: Forwards packets "as-is" in I/O mode.
328  This is the fastest possible forwarding operation as it does not access packets data.
329  This is the default mode.
330
331* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
332  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
333  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
334  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
335
336* ``macswap``: MAC swap forwarding mode.
337  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
338
339* ``flowgen``: Multi-flow generation mode.
340  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
341
342* ``rxonly``: Receives packets but doesn't transmit them.
343
344* ``txonly``: Generates and transmits packets without receiving any.
345
346* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
347
348* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
349
350* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
351
352* ``noisy``: Noisy neighbor simulation.
353  Simulate more realistic behavior of a guest machine engaged in receiving
354  and sending packets performing Virtual Network Function (VNF).
355
356* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
357
358  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
359
360  L3 swaps the source address and destination address of IP (v4 and v6).
361
362  L4 swaps the source port and destination port of transport layer (TCP and UDP).
363
364* ``shared-rxq``: Receive only for shared Rx queue.
365  Resolve packet source port from mbuf and update stream statistics accordingly.
366
367Example::
368
369   testpmd> set fwd rxonly
370
371   Set rxonly packet forwarding mode
372
373
374show fwd
375~~~~~~~~
376
377When running, forwarding engines maintain statistics from the time they have been started.
378Example for the io forwarding engine, with some packet drops on the tx side::
379
380   testpmd> show fwd stats all

641Configuration Functions
642-----------------------
643
644The testpmd application can be configured from the runtime as well as from the command-line.
645
646This section details the available configuration functions that are available.
647
648.. note::
649
650   Configuration changes only become active when forwarding is started/restarted.
651
652set default
653~~~~~~~~~~~
654
655Reset forwarding to the default configuration::
656
657   testpmd> set default
658
659set verbose
660~~~~~~~~~~~
661
662Set the debug verbosity level::
663
664   testpmd> set verbose (level)
665
666Available levels are as following:
667
668* ``0`` silent except for error.
669* ``1`` fully verbose except for Tx packets.
670* ``2`` fully verbose except for Rx packets.
671* ``> 2`` fully verbose.
672

674~~~~~~~
675
676Set the log level for a log type::
677
678	testpmd> set log global|(type) (level)
679
680Where:
681
682* ``type`` is the log name.
683
684* ``level`` is the log level.
685
686For example, to change the global log level::
687
688	testpmd> set log global (level)
689
690Regexes can also be used for type. To change log level of user1, user2 and user3::
691
692	testpmd> set log user[1-3] (level)
693
694set nbport
695~~~~~~~~~~
696
697Set the number of ports used by the application:
698
699set nbport (num)
700
701This is equivalent to the ``--nb-ports`` command-line option.
702
703set nbcore
704~~~~~~~~~~
705
706Set the number of cores used by the application::
707
708   testpmd> set nbcore (num)
709
710This is equivalent to the ``--nb-cores`` command-line option.
711
712.. note::
713
714   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
715
716set coremask
717~~~~~~~~~~~~
718
719Set the forwarding cores hexadecimal mask::
720
721   testpmd> set coremask (mask)
722
723This is equivalent to the ``--coremask`` command-line option.
724
725.. note::
726
727   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
728
729set portmask
730~~~~~~~~~~~~
731
732Set the forwarding ports hexadecimal mask::
733
734   testpmd> set portmask (mask)
735
736This is equivalent to the ``--portmask`` command-line option.
737
738set record-core-cycles
739~~~~~~~~~~~~~~~~~~~~~~
740
741Set the recording of CPU cycles::
742
743   testpmd> set record-core-cycles (on|off)
744
745Where:
746
747* ``on`` enables measurement of CPU cycles per packet.
748
749* ``off`` disables measurement of CPU cycles per packet.
750
751This is equivalent to the ``--record-core-cycles command-line`` option.
752
753set record-burst-stats
754~~~~~~~~~~~~~~~~~~~~~~
755
756Set the displaying of RX and TX bursts::
757
758   testpmd> set record-burst-stats (on|off)
759
760Where:
761
762* ``on`` enables display of RX and TX bursts.
763
764* ``off`` disables display of RX and TX bursts.
765
766This is equivalent to the ``--record-burst-stats command-line`` option.
767
768set burst
769~~~~~~~~~
770
771Set number of packets per burst::
772
773   testpmd> set burst (num)
774
775This is equivalent to the ``--burst command-line`` option.
776
777When retry is enabled, the transmit delay time and number of retries can also be set::
778
779   testpmd> set burst tx delay (microseconds) retry (num)
780
781set rxoffs
782~~~~~~~~~~
783
784Set the offsets of segments relating to the data buffer beginning on receiving
785if split feature is engaged. Affects only the queues configured with split
786offloads (currently BUFFER_SPLIT is supported only).
787
788   testpmd> set rxoffs (x[,y]*)
789
790Where x[,y]* represents a CSV list of values, without white space. If the list
791of offsets is shorter than the list of segments the zero offsets will be used
792for the remaining segments.
793
794set rxpkts
795~~~~~~~~~~
796
797Set the length of segments to scatter packets on receiving if split
798feature is engaged. Affects only the queues configured with split offloads
799(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
800pools can be specified with --mbuf-size command line parameter and the mbufs
801to receive will be allocated sequentially from these extra memory pools (the
802mbuf for the first segment is allocated from the first pool, the second one
803from the second pool, and so on, if segment number is greater then pool's the
804mbuf for remaining segments will be allocated from the last valid pool).
805
806   testpmd> set rxpkts (x[,y]*)
807
808Where x[,y]* represents a CSV list of values, without white space. Zero value
809means to use the corresponding memory pool data buffer size.
810
811set rxhdrs
812~~~~~~~~~~
813
814Set the protocol headers of segments to scatter packets on receiving
815if split feature is engaged.
816Affects only the queues configured with split offloads
817(currently BUFFER_SPLIT is supported only).
818
819   testpmd> set rxhdrs (eth[,ipv4]*)
820
821Where eth[,ipv4]* represents a CSV list of values, without white space.
822If the list of offsets is shorter than the list of segments,
823zero offsets will be used for the remaining segments.
824
825set txpkts
826~~~~~~~~~~
827
828Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
829
830   testpmd> set txpkts (x[,y]*)
831
832Where x[,y]* represents a CSV list of values, without white space.
833
834set txtimes
835~~~~~~~~~~~
836
837Configure the timing burst pattern for Tx only mode. This command enables
838the packet send scheduling on dynamic timestamp mbuf field and configures
839timing pattern in Tx only mode. In this mode, if scheduling is enabled
840application provides timestamps in the packets being sent. It is possible
841to configure delay (in unspecified device clock units) between bursts
842and between the packets within the burst::
843
844   testpmd> set txtimes (inter),(intra)
845
846where:
847
848* ``inter``  is the delay between the bursts in the device clock units.
849  If ``intra`` is zero, this is the time between the beginnings of the
850  first packets in the neighbour bursts, if ``intra`` is not zero,
851  ``inter`` specifies the time between the beginning of the first packet
852  of the current burst and the beginning of the last packet of the
853  previous burst. If ``inter`` parameter is zero the send scheduling
854  on timestamps is disabled (default).
855
856* ``intra`` is the delay between the packets within the burst specified
857  in the device clock units. The number of packets in the burst is defined
858  by regular burst setting. If ``intra`` parameter is zero no timestamps
859  provided in the packets excepting the first one in the burst.
860
861As the result the bursts of packet will be transmitted with specific
862delays between the packets within the burst and specific delay between
863the bursts. The rte_eth_read_clock() must be supported by the device(s)
864and is supposed to be engaged to get the current device clock value
865and provide the reference for the timestamps. If there is no supported
866rte_eth_read_clock() there will be no send scheduling provided on the port.
867
868set txsplit
869~~~~~~~~~~~
870
871Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
872
873   testpmd> set txsplit (off|on|rand)
874
875Where:
876
877* ``off`` disable packet copy & split for CSUM mode.
878
879* ``on`` split outgoing packet into multiple segments. Size of each segment
880  and number of segments per packet is determined by ``set txpkts`` command
881  (see above).
882
883* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
884
885set corelist
886~~~~~~~~~~~~
887
888Set the list of forwarding cores::
889
890   testpmd> set corelist (x[,y]*)
891
892For example, to change the forwarding cores:
893
894.. code-block:: console
895
896   testpmd> set corelist 3,1
897   testpmd> show config fwd
898
899   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
900   Logical Core 3 (socket 0) forwards packets on 1 streams:
901   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
902   Logical Core 1 (socket 0) forwards packets on 1 streams:
903   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
904
905.. note::

919
920   testpmd> set portlist 0,2,1,3
921   testpmd> show config fwd
922
923   io packet forwarding - ports=4 - cores=1 - streams=4
924   Logical Core 3 (socket 0) forwards packets on 4 streams:
925   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
926   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
927   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
928   RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02

1082
1083   testpmd> tx_vlan reset (port_id)
1084
1085csum set
1086~~~~~~~~
1087
1088Select hardware or software calculation of the checksum when
1089transmitting a packet using the ``csum`` forwarding engine::
1090
1091   testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
1092
1093Where:
1094
1095* ``ip|udp|tcp|sctp`` always relate to  the inner layer.
1096
1097* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
1098  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1099  supported). See also the ``csum parse-tunnel`` command.
1100
1101* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1102  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1103  supported). See also the ``csum parse-tunnel`` command.
1104
1105.. note::
1106
1107   Check the NIC Datasheet for hardware limits.
1108
1109csum parse-tunnel
1110~~~~~~~~~~~~~~~~~
1111
1112Define how tunneled packets should be handled by the csum forward
1113engine::
1114
1115   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1116
1117If enabled, the csum forward engine will try to recognize supported
1118tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1119
1120If disabled, treat tunnel packets as non-tunneled packets (a inner
1121header is handled as a packet payload).
1122
1123.. note::
1124
1125   The port argument is the TX port like in the ``csum set`` command.
1126
1127Example:
1128
1129Consider a packet in packet like the following::
1130
1131   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1132
1133* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1134  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1135  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1136
1137* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1138   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1185
1186If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1187packets received from the given port.
1188
1189If disabled, packets received from the given port won't be performed
1190GRO. By default, GRO is disabled for all ports.
1191
1192.. note::
1193
1194   When enable GRO for a port, TCP/IPv4 packets received from the port
1195   will be performed GRO. After GRO, all merged packets have bad
1196   checksums, since the GRO library doesn't re-calculate checksums for
1197   the merged packets. Therefore, if users want the merged packets to
1198   have correct checksums, please select HW IP checksum calculation and
1199   HW TCP checksum calculation for the port which the merged packets are
1200   transmitted to.
1201
1202show port - gro
1203~~~~~~~~~~~~~~~
1204
1205Display GRO configuration for a given port::
1206
1207   testpmd> show port <port_id> gro
1208
1209set gro flush
1210~~~~~~~~~~~~~
1211
1212Set the cycle to flush the GROed packets from reassembly tables::
1213
1214   testpmd> set gro flush <cycles>
1215
1216When enable GRO, the csum forwarding engine performs GRO on received
1217packets, and the GROed packets are stored in reassembly tables. Users
1218can use this command to determine when the GROed packets are flushed
1219from the reassembly tables.
1220
1221The ``cycles`` is measured in GRO operation times. The csum forwarding
1222engine flushes the GROed packets from the tables every ``cycles`` GRO
1223operations.
1224
1225By default, the value of ``cycles`` is 1, which means flush GROed packets
1226from the reassembly tables as soon as one GRO operation finishes. The value
1227of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1228
1229Please note that the large value of ``cycles`` may cause the poor TCP/IP
1230stack performance. Because the GROed packets are delayed to arrive the
1231stack, thus causing more duplicated ACKs and TCP retransmissions.
1232
1233set port - gso
1234~~~~~~~~~~~~~~
1235
1236Toggle per-port GSO support in ``csum`` forwarding engine::
1237
1238   testpmd> set port <port_id> gso on|off
1239
1240If enabled, the csum forwarding engine will perform GSO on supported IPv4
1241packets, transmitted on the given port.
1242
1243If disabled, packets transmitted on the given port will not undergo GSO.
1244By default, GSO is disabled for all ports.
1245
1246.. note::
1247
1248   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1249   port undergo GSO. Afterwards, the segmented packets are represented by
1250   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1251   of checksums for GSO'd segments in SW. As a result, if users want correct
1252   checksums in GSO segments, they should enable HW checksum calculation for
1253   GSO-enabled ports.
1254
1255   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1256   by setting the following options in the csum forwarding engine:
1257
1258   testpmd> csum set outer_ip hw <port_id>
1259
1260   testpmd> csum set ip hw <port_id>
1261
1262   testpmd> csum set tcp hw <port_id>
1263
1264   UDP GSO is the same as IP fragmentation, which treats the UDP header
1265   as the payload and does not modify it during segmentation. That is,
1266   after UDP GSO, only the first output fragment has the original UDP
1267   header. Therefore, users need to enable HW IP checksum calculation
1268   and SW UDP checksum calculation for GSO-enabled ports, if they want
1269   correct checksums for UDP/IPv4 packets.
1270
1271set gso segsz

1689
1690These commands will set an internal configuration inside testpmd, any following
1691flow rule using the action mplsogre_encap will use the last configuration set.
1692To have a different encapsulation header, one of those commands must be called
1693before the flow rule creation.

1737
1738Config Raw Encapsulation
1739~~~~~~~~~~~~~~~~~~~~~~~~~
1740
1741Configure the raw data to be used when encapsulating a packet by
1742rte_flow_action_raw_encap::
1743
1744 set raw_encap {index} {item} [/ {item} [...]] / end_set
1745
1746There are multiple global buffers for ``raw_encap``, this command will set one
1747internal buffer index by ``{index}``.
1748If there is no ``{index}`` specified::
1749
1750 set raw_encap {item} [/ {item} [...]] / end_set
1751
1752the default index ``0`` is used.
1753In order to use different encapsulating header, ``index`` must be specified
1754during the flow rule creation::
1755
1756 testpmd> flow create 0 egress pattern eth / ipv4 / end actions
1757        raw_encap index 2 / end
1758
1759Otherwise the default index ``0`` is used.

1810Port Functions
1811--------------
1812
1813The following sections show functions for configuring ports.
1814
1815.. note::
1816
1817   Port configuration changes only become active when forwarding is started/restarted.
1818
1819.. _port_attach:
1820
1821port attach
1822~~~~~~~~~~~
1823
1824Attach a port specified by pci address or virtual device args::
1825
1826   testpmd> port attach (identifier)
1827
1828To attach a new pci device, the device should be recognized by kernel first.
1829Then it should be moved under DPDK management.
1830Finally the port can be attached to testpmd.
1831
1832For example, to move a pci device using ixgbe under DPDK management:
1833
1834.. code-block:: console
1835
1836   # Check the status of the available devices.
1837   ./usertools/dpdk-devbind.py --status
1838
1839   Network devices using DPDK-compatible driver
1840   ============================================
1841   <none>
1842
1843   Network devices using kernel driver
1844   ===================================
1845   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1846
1847
1848   # Bind the device to igb_uio.
1849   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1850
1851
1852   # Recheck the status of the devices.
1853   ./usertools/dpdk-devbind.py --status
1854   Network devices using DPDK-compatible driver
1855   ============================================
1856   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1857
1858To attach a port created by virtual device, above steps are not needed.
1859
1860For example, to attach a port whose pci address is 0000:0a:00.0.
1861
1862.. code-block:: console
1863
1864   testpmd> port attach 0000:0a:00.0
1865   Attaching a new port...
1866   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1867   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
1868   EAL:   PCI memory mapped at 0x7f83bfa00000
1869   EAL:   PCI memory mapped at 0x7f83bfa80000
1870   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1871   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1872   Port 0 is attached. Now total ports is 1
1873   Done
1874
1875For example, to attach a port created by pcap PMD.
1876
1877.. code-block:: console
1878
1879   testpmd> port attach net_pcap0
1880   Attaching a new port...
1881   PMD: Initializing pmd_pcap for net_pcap0
1882   PMD: Creating pcap-backed ethdev on numa socket 0
1883   Port 0 is attached. Now total ports is 1
1884   Done
1885
1886In this case, identifier is ``net_pcap0``.
1887This identifier format is the same as ``--vdev`` format of DPDK applications.
1888
1889For example, to re-attach a bonded port which has been previously detached,
1890the mode and slave parameters must be given.
1891
1892.. code-block:: console
1893
1894   testpmd> port attach net_bond_0,mode=0,slave=1
1895   Attaching a new port...
1896   EAL: Initializing pmd_bond for net_bond_0
1897   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1898   Port 0 is attached. Now total ports is 1
1899   Done
1900
1901
1902port detach
1903~~~~~~~~~~~
1904
1905Detach a specific port::
1906
1907   testpmd> port detach (port_id)
1908
1909Before detaching a port, the port should be stopped and closed.
1910
1911For example, to detach a pci device port 0.
1912
1913.. code-block:: console
1914
1915   testpmd> port stop 0
1916   Stopping ports...
1917   Done
1918   testpmd> port close 0
1919   Closing ports...
1920   Done
1921
1922   testpmd> port detach 0
1923   Detaching a port...
1924   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1925   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
1926   EAL:   PCI memory unmapped at 0x7f83bfa00000
1927   EAL:   PCI memory unmapped at 0x7f83bfa80000
1928   Done
1929
1930
1931For example, to detach a virtual device port 0.
1932
1933.. code-block:: console
1934
1935   testpmd> port stop 0
1936   Stopping ports...
1937   Done
1938   testpmd> port close 0
1939   Closing ports...
1940   Done
1941
1942   testpmd> port detach 0
1943   Detaching a port...
1944   PMD: Closing pcap ethdev on numa socket 0
1945   Port 'net_pcap0' is detached. Now total ports is 0
1946   Done
1947
1948To remove a pci device completely from the system, first detach the port from testpmd.
1949Then the device should be moved under kernel management.
1950Finally the device can be removed using kernel pci hotplug functionality.
1951
1952For example, to move a pci device under kernel management:
1953
1954.. code-block:: console
1955
1956   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1957
1958   ./usertools/dpdk-devbind.py --status

2193Add/remove UDP tunnel port for VXLAN/GENEVE tunneling protocols::
2194
2195    testpmd> port config (port_id) udp_tunnel_port add|rm vxlan|geneve|vxlan-gpe|ecpri (udp_port)
2196
2197port config tx_metadata
2198~~~~~~~~~~~~~~~~~~~~~~~
2199
2200Set Tx metadata value per port.
2201testpmd will add this value to any Tx packet sent from this port::
2202
2203   testpmd> port config (port_id) tx_metadata (value)
2204
2205port config dynf
2206~~~~~~~~~~~~~~~~
2207
2208Set/clear dynamic flag per port.
2209testpmd will register this flag in the mbuf (same registration
2210for both Tx and Rx). Then set/clear this flag for each Tx
2211packet sent from this port. The set bit only works for Tx packet::
2212
2213   testpmd> port config (port_id) dynf (name) (set|clear)
2214
2215port config mtu
2216~~~~~~~~~~~~~~~
2217

2219
2220   testpmd> port config mtu (port_id) (value)
2221
2222port config rss hash key
2223~~~~~~~~~~~~~~~~~~~~~~~~
2224
2225To configure the RSS hash key used to compute the RSS
2226hash of input [IP] packets received on port::
2227
2228   testpmd> port config <port_id> rss-hash-key (ipv4|ipv4-frag|\
2229                     ipv4-tcp|ipv4-udp|ipv4-sctp|ipv4-other|\
2230                     ipv6|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp|\

2238To cleanup txq mbufs currently cached by driver::
2239
2240   testpmd> port cleanup (port_id) txq (queue_id) (free_cnt)
2241
2242If the value of ``free_cnt`` is 0, driver should free all cached mbufs.

2244Device Functions
2245----------------
2246
2247The following sections show functions for device operations.
2248
2249device detach
2250~~~~~~~~~~~~~
2251
2252Detach a device specified by pci address or virtual device args::
2253
2254   testpmd> device detach (identifier)
2255
2256Before detaching a device associated with ports, the ports should be stopped and closed.
2257
2258For example, to detach a pci device whose address is 0002:03:00.0.
2259
2260.. code-block:: console
2261
2262    testpmd> device detach 0002:03:00.0
2263    Removing a device...
2264    Port 1 is now closed
2265    EAL: Releasing pci mapped resource for 0002:03:00.0
2266    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2267    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2268    Device 0002:03:00.0 is detached
2269    Now total ports is 1
2270
2271For example, to detach a port created by pcap PMD.
2272
2273.. code-block:: console
2274
2275    testpmd> device detach net_pcap0
2276    Removing a device...
2277    Port 0 is now closed
2278    Device net_pcap0 is detached
2279    Now total ports is 0
2280    Done
2281
2282In this case, identifier is ``net_pcap0``.
2283This identifier format is the same as ``--vdev`` format of DPDK applications.
2284

2853Congestion Management
2854---------------------
2855
2856Get capabilities
2857~~~~~~~~~~~~~~~~
2858

2881
2882Filter Functions
2883----------------
2884
2885This section details the available filter functions that are available.
2886
2887Note these functions interface the deprecated legacy filtering framework,
2888superseded by *rte_flow*. See `Flow rules management`_.
2889
2890.. _testpmd_rte_flow:
2891
2892Flow rules management
2893---------------------
2894
2895Control of the generic flow API (*rte_flow*) is fully exposed through the
2896``flow`` command (configuration, validation, creation, destruction, queries
2897and operation modes).
2898
2899Considering *rte_flow* overlaps with all `Filter Functions`_, using both
2900features simultaneously may cause undefined side-effects and is therefore
2901not recommended.
2902
2903``flow`` syntax
2904~~~~~~~~~~~~~~~
2905
2906Because the ``flow`` command uses dynamic tokens to handle the large number
2907of possible flow rules combinations, its behavior differs slightly from
2908other commands, in particular:
2909
2910- Pressing *?* or the *<tab>* key displays contextual help for the current
2911  token, not that of the entire command.
2912
2913- Optional and repeated parameters are supported (provided they are listed
2914  in the contextual help).
2915
2916The first parameter stands for the operation mode. Possible operations and
2917their general syntax are described below. They are covered in detail in the
2918following sections.

3265~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3266
3267``flow tunnel destroy`` destroy port tunnel stub::
3268
3269   flow tunnel destroy {port_id} id {tunnel_id}
3270
3271Listing tunnel offload stubs
3272~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3273
3274``flow tunnel list`` list port tunnel offload stubs::
3275
3276   flow tunnel list {port_id}
3277
3278Validating flow rules
3279~~~~~~~~~~~~~~~~~~~~~
3280
3281``flow validate`` reports whether a flow rule would be accepted by the
3282underlying device in its current state but stops short of creating it. It is
3283bound to ``rte_flow_validate()``::
3284
3285   flow validate {port_id}
3286      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3287      pattern {item} [/ {item} [...]] / end
3288      actions {action} [/ {action} [...]] / end
3289
3290If successful, it will show::
3291
3292   Flow rule validated
3293
3294Otherwise it will show an error message of the form::
3295
3296   Caught error type [...] ([...]): [...]
3297
3298This command uses the same parameters as ``flow create``, their format is
3299described in `Creating flow rules`_.
3300
3301Check whether redirecting any Ethernet packet received on port 0 to RX queue
3302index 6 is supported::
3303
3304   testpmd> flow validate 0 ingress pattern eth / end
3305      actions queue index 6 / end
3306   Flow rule validated
3307   testpmd>
3308
3309Port 0 does not support TCPv6 rules::
3310
3311   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3312      actions drop / end
3313   Caught error type 9 (specific pattern item): Invalid argument
3314   testpmd>
3315
3316Creating flow rules
3317~~~~~~~~~~~~~~~~~~~
3318
3319``flow create`` validates and creates the specified flow rule. It is bound
3320to ``rte_flow_create()``::
3321
3322   flow create {port_id}
3323      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3324      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3325      pattern {item} [/ {item} [...]] / end
3326      actions {action} [/ {action} [...]] / end
3327
3328If successful, it will return a flow rule ID usable with other commands::
3329
3330   Flow rule #[...] created
3331
3332Otherwise it will show an error message of the form::
3333
3334   Caught error type [...] ([...]): [...]
3335
3336Parameters describe in the following order:
3337
3338- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3339- Tunnel offload specification (tunnel_set, tunnel_match)
3340- A matching pattern, starting with the *pattern* token and terminated by an
3341  *end* pattern item.
3342- Actions, starting with the *actions* token and terminated by an *end*
3343  action.
3344
3345These translate directly to *rte_flow* objects provided as-is to the
3346underlying functions.
3347
3348The shortest valid definition only comprises mandatory tokens::
3349
3350   testpmd> flow create 0 pattern end actions end
3351
3352Note that PMDs may refuse rules that essentially do nothing such as this
3353one.
3354
3355**All unspecified object values are automatically initialized to 0.**
3356
3357Enqueueing creation of flow rules
3358~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3359
3360``flow queue create`` adds creation operation of a flow rule to a queue.
3361It is bound to ``rte_flow_async_create()``::
3362
3363   flow queue {port_id} create {queue_id}
3364       [postpone {boolean}] template_table {table_id}
3365       pattern_template {pattern_template_index}
3366       actions_template {actions_template_index}
3367       pattern {item} [/ {item} [...]] / end
3368       actions {action} [/ {action} [...]] / end
3369
3370If successful, it will return a flow rule ID usable with other commands::
3371
3372   Flow rule #[...] creaion enqueued
3373
3374Otherwise it will show an error message of the form::
3375
3376   Caught error type [...] ([...]): [...]
3377
3378This command uses the same pattern items and actions as ``flow create``,
3379their format is described in `Creating flow rules`_.
3380
3381``flow queue pull`` must be called to retrieve the operation status.
3382
3383Attributes
3384^^^^^^^^^^
3385
3386These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3387specified before the ``pattern`` token.
3388
3389- ``group {group id}``: priority group.
3390- ``priority {level}``: priority level within group.
3391- ``ingress``: rule applies to ingress traffic.
3392- ``egress``: rule applies to egress traffic.
3393- ``transfer``: apply rule directly to endpoints found in pattern.
3394
3395Please note that use of ``transfer`` attribute requires that the flow and
3396its indirect components be managed via so-called ``transfer`` proxy port.
3397See `show flow transfer proxy port ID for the given port`_ for details.
3398
3399Each instance of an attribute specified several times overrides the previous
3400value as shown below (group 4 is used)::
3401
3402   testpmd> flow create 0 group 42 group 24 group 4 [...]
3403
3404Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3405
3406While not specifying a direction is an error, some rules may allow both
3407simultaneously.
3408
3409Most rules affect RX therefore contain the ``ingress`` token::
3410
3411   testpmd> flow create 0 ingress pattern [...]
3412
3413Tunnel offload
3414^^^^^^^^^^^^^^
3415
3416Indicate tunnel offload rule type
3417
3418- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3419- ``tunnel_match {tunnel_id}``:  mark rule as tunnel offload match type.
3420
3421Matching pattern
3422^^^^^^^^^^^^^^^^
3423
3424A matching pattern starts after the ``pattern`` token. It is made of pattern
3425items and is terminated by a mandatory ``end`` item.
3426
3427Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3428rte_flow_item_type``).
3429
3430The ``/`` token is used as a separator between pattern items as shown
3431below::
3432
3433   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3434
3435Note that protocol items like these must be stacked from lowest to highest
3436layer to make sense. For instance, the following rule is either invalid or
3437unlikely to match any packet::
3438
3439   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3440
3441More information on these restrictions can be found in the *rte_flow*
3442documentation.
3443
3444Several items support additional specification structures, for example
3445``ipv4`` allows specifying source and destination addresses as follows::
3446
3447   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3448      dst is 10.2.0.0 / end [...]
3449
3450This rule matches all IPv4 traffic with the specified properties.
3451
3452In this example, ``src`` and ``dst`` are field names of the underlying
3453``struct rte_flow_item_ipv4`` object. All item properties can be specified
3454in a similar fashion.
3455
3456The ``is`` token means that the subsequent value must be matched exactly,
3457and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3458accordingly. Possible assignment tokens are:
3459
3460- ``is``: match value perfectly (with full bit-mask).
3461- ``spec``: match value according to configured bit-mask.
3462- ``last``: specify upper bound to establish a range.
3463- ``mask``: specify bit-mask with relevant bits set to one.
3464- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3465
3466These yield identical results::
3467
3468   ipv4 src is 10.1.1.1
3469
3470::
3471
3472   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3473
3474::
3475
3476   ipv4 src spec 10.1.1.1 src prefix 32
3477
3478::
3479
3480   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3481
3482::
3483
3484   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3485
3486Inclusive ranges can be defined with ``last``::
3487
3488   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3489
3490Note that ``mask`` affects both ``spec`` and ``last``::
3491
3492   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3493      # matches 10.1.0.0 to 10.2.255.255
3494
3495Properties can be modified multiple times::
3496
3497   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3498
3499::
3500
3501   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3502

3752
3753
3754Actions list
3755^^^^^^^^^^^^
3756
3757A list of actions starts after the ``actions`` token in the same fashion as
3758`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3759terminated by a mandatory ``end`` action.
3760
3761Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3762rte_flow_action_type``).
3763
3764Dropping all incoming UDPv4 packets can be expressed as follows::
3765
3766   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3767      actions drop / end
3768
3769Several actions have configurable properties which must be specified when
3770there is no valid default value. For example, ``queue`` requires a target
3771queue index.
3772
3773This rule redirects incoming UDPv4 traffic to queue index 6::
3774
3775   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3776      actions queue index 6 / end
3777
3778While this one could be rejected by PMDs (unspecified queue index)::
3779
3780   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3781      actions queue / end
3782
3783As defined by *rte_flow*, the list is not ordered, all actions of a given
3784rule are performed simultaneously. These are equivalent::
3785
3786   queue index 6 / void / mark id 42 / end
3787
3788::
3789
3790   void / mark id 42 / queue index 6 / end
3791
3792All actions in a list should have different types, otherwise only the last
3793action of a given type is taken into account::
3794
3795   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3796
3797::
3798
3799   drop / drop / drop / end # drop is performed only once
3800
3801::
3802
3803   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3804
3805Considering they are performed simultaneously, opposite and overlapping
3806actions can sometimes be combined when the end result is unambiguous::
3807
3808   drop / queue index 6 / end # drop has no effect
3809
3810::
3811
3812   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3813
3814::
3815
3816   drop / passthru / end # drop has no effect
3817
3818Note that PMDs may still refuse such combinations.

4042Destroying flow rules
4043~~~~~~~~~~~~~~~~~~~~~
4044
4045``flow destroy`` destroys one or more rules from their rule ID (as returned
4046by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4047times as necessary::
4048
4049   flow destroy {port_id} rule {rule_id} [...]
4050
4051If successful, it will show::
4052
4053   Flow rule #[...] destroyed
4054
4055It does not report anything for rule IDs that do not exist. The usual error
4056message is shown when a rule cannot be destroyed::
4057
4058   Caught error type [...] ([...]): [...]
4059
4060``flow flush`` destroys all rules on a device and does not take extra
4061arguments. It is bound to ``rte_flow_flush()``::
4062
4063   flow flush {port_id}
4064
4065Any errors are reported as above.
4066
4067Creating several rules and destroying them::
4068
4069   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4070      actions queue index 2 / end
4071   Flow rule #0 created
4072   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4073      actions queue index 3 / end
4074   Flow rule #1 created
4075   testpmd> flow destroy 0 rule 0 rule 1
4076   Flow rule #1 destroyed
4077   Flow rule #0 destroyed
4078   testpmd>
4079
4080The same result can be achieved using ``flow flush``::
4081
4082   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4083      actions queue index 2 / end
4084   Flow rule #0 created
4085   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4086      actions queue index 3 / end
4087   Flow rule #1 created
4088   testpmd> flow flush 0
4089   testpmd>
4090
4091Non-existent rule IDs are ignored::
4092
4093   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4094      actions queue index 2 / end
4095   Flow rule #0 created
4096   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4097      actions queue index 3 / end
4098   Flow rule #1 created
4099   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4100   testpmd>
4101   testpmd> flow destroy 0 rule 0
4102   Flow rule #0 destroyed
4103   testpmd>
4104
4105Enqueueing destruction of flow rules
4106~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4107
4108``flow queue destroy`` adds destruction operations to destroy one or more rules
4109from their rule ID (as returned by ``flow queue create``) to a queue,
4110this command calls ``rte_flow_async_destroy()`` as many times as necessary::
4111
4112   flow queue {port_id} destroy {queue_id}
4113        [postpone {boolean}] rule {rule_id} [...]
4114
4115If successful, it will show::
4116
4117   Flow rule #[...] destruction enqueued
4118
4119It does not report anything for rule IDs that do not exist. The usual error
4120message is shown when a rule cannot be destroyed::
4121
4122   Caught error type [...] ([...]): [...]
4123
4124``flow queue pull`` must be called to retrieve the operation status.
4125
4126Querying flow rules
4127~~~~~~~~~~~~~~~~~~~
4128
4129``flow query`` queries a specific action of a flow rule having that
4130ability. Such actions collect information that can be reported using this
4131command. It is bound to ``rte_flow_query()``::
4132
4133   flow query {port_id} {rule_id} {action}
4134
4135If successful, it will display either the retrieved data for known actions
4136or the following message::
4137
4138   Cannot display result for action type [...] ([...])
4139
4140Otherwise, it will complain either that the rule does not exist or that some
4141error occurred::
4142
4143   Flow rule #[...] not found
4144
4145::
4146
4147   Caught error type [...] ([...]): [...]
4148
4149Currently only the ``count`` action is supported. This action reports the
4150number of packets that hit the flow rule and the total number of bytes. Its
4151output has the following format::
4152
4153   count:
4154    hits_set: [...] # whether "hits" contains a valid value
4155    bytes_set: [...] # whether "bytes" contains a valid value
4156    hits: [...] # number of packets
4157    bytes: [...] # number of bytes
4158
4159Querying counters for TCPv6 packets redirected to queue 6::
4160
4161   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4162      actions queue index 6 / count / end
4163   Flow rule #4 created
4164   testpmd> flow query 0 4 count
4165   count:
4166    hits_set: 1
4167    bytes_set: 0
4168    hits: 386446
4169    bytes: 0
4170   testpmd>
4171
4172Listing flow rules
4173~~~~~~~~~~~~~~~~~~
4174
4175``flow list`` lists existing flow rules sorted by priority and optionally
4176filtered by group identifiers::
4177
4178   flow list {port_id} [group {group_id}] [...]
4179
4180This command only fails with the following message if the device does not
4181exist::
4182
4183   Invalid port [...]
4184
4185Output consists of a header line followed by a short description of each
4186flow rule, one per line. There is no output at all when no flow rules are
4187configured on the device::
4188
4189   ID      Group   Prio    Attr    Rule
4190   [...]   [...]   [...]   [...]   [...]
4191
4192``Attr`` column flags:
4193
4194- ``i`` for ``ingress``.
4195- ``e`` for ``egress``.
4196
4197Creating several flow rules and listing them::
4198
4199   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4200      actions queue index 6 / end
4201   Flow rule #0 created
4202   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4203      actions queue index 2 / end
4204   Flow rule #1 created
4205   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4206      actions rss queues 6 7 8 end / end
4207   Flow rule #2 created
4208   testpmd> flow list 0
4209   ID      Group   Prio    Attr    Rule
4210   0       0       0       i-      ETH IPV4 => QUEUE
4211   1       0       0       i-      ETH IPV6 => QUEUE
4212   2       0       5       i-      ETH IPV4 UDP => RSS
4213   testpmd>
4214
4215Rules are sorted by priority (i.e. group ID first, then priority level)::
4216
4217   testpmd> flow list 1
4218   ID      Group   Prio    Attr    Rule
4219   0       0       0       i-      ETH => COUNT
4220   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4221   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4222   1       24      0       i-      ETH IPV4 UDP => QUEUE
4223   4       24      10      i-      ETH IPV4 TCP => DROP
4224   3       24      20      i-      ETH IPV4 => DROP
4225   2       24      42      i-      ETH IPV4 UDP => QUEUE
4226   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4227   testpmd>
4228
4229Output can be limited to specific groups::
4230
4231   testpmd> flow list 1 group 0 group 63
4232   ID      Group   Prio    Attr    Rule
4233   0       0       0       i-      ETH => COUNT
4234   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4235   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4236   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4237   testpmd>
4238
4239Toggling isolated mode
4240~~~~~~~~~~~~~~~~~~~~~~
4241
4242``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4243must only be injected from the defined flow rules; that no default traffic
4244is expected outside those rules and the driver is free to assign more
4245resources to handle them. It is bound to ``rte_flow_isolate()``::
4246
4247 flow isolate {port_id} {boolean}
4248
4249If successful, enabling or disabling isolated mode shows either::
4250
4251 Ingress traffic on port [...]
4252    is now restricted to the defined flow rules
4253
4254Or::
4255
4256 Ingress traffic on port [...]
4257    is not restricted anymore to the defined flow rules
4258
4259Otherwise, in case of error::
4260
4261   Caught error type [...] ([...]): [...]
4262
4263Mainly due to its side effects, PMDs supporting this mode may not have the
4264ability to toggle it more than once without reinitializing affected ports
4265first (e.g. by exiting testpmd).
4266
4267Enabling isolated mode::
4268
4269 testpmd> flow isolate 0 true
4270 Ingress traffic on port 0 is now restricted to the defined flow rules
4271 testpmd>
4272
4273Disabling isolated mode::
4274
4275 testpmd> flow isolate 0 false
4276 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4277 testpmd>
4278
4279Dumping HW internal information
4280~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4281
4282``flow dump`` dumps the hardware's internal representation information of
4283all flows. It is bound to ``rte_flow_dev_dump()``::
4284
4285   flow dump {port_id} {output_file}
4286
4287If successful, it will show::
4288
4289   Flow dump finished
4290
4291Otherwise, it will complain error occurred::
4292
4293   Caught error type [...] ([...]): [...]
4294
4295Listing and destroying aged flow rules
4296~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4297
4298``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4299and ``destroy`` parameter can be used to destroy those flow rules in PMD::
4300

4321Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4322information, all the aged flows are sorted by the longest timeout time. For example, if
4323those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4324will be ID 3, ID 1, ID 0::
4325

5042its representor ethdev (port 1), mirror 50% of them to the
5043said representor (for bookkeeping) as well as encapsulate
5044all the packets and steer them to the physical port:
5045
5046::
5047
5048   testpmd> set sample_actions 0 port_representor ethdev_port_id 1 / end
5049

5058
5059Sample integrity rules
5060~~~~~~~~~~~~~~~~~~~~~~
5061
5062Integrity rules can be created by the following commands:
5063
5064Integrity rule that forwards valid TCP packets to group 1.
5065TCP packet integrity is matched with the ``l4_ok`` bit 3.
5066
5067::
5068
5069 testpmd> flow create 0 ingress
5070            pattern eth / ipv4 / tcp / integrity value mask 8 value spec 8 / end
5071            actions jump group 1 / end
5072
5073Integrity rule that forwards invalid packets to application.
5074General packet integrity is matched with the ``packet_ok`` bit 0.
5075
5076::
5077
5078 testpmd> flow create 0 ingress pattern integrity value mask 1 value spec 0 / end actions queue index 0 / end

5082
5083Conntrack rules can be set by the following commands
5084
5085Need to construct the connection context with provided information.
5086In the first table, create a flow rule by using conntrack action and jump to
5087the next table. In the next table, create a rule to check the state.
5088
5089::
5090
5091 testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
5092        last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510

5103 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
5104
5105Construct the conntrack again with only "is_orig" set to 0 (other fields are
5106ignored), then use "update" interface to update the direction. Create flow
5107rules like above for the peer port.
5108
5109::
5110
5111 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
5112

5153Sample L2TPv2 FDIR rules
5154~~~~~~~~~~~~~~~~~~~~~~~~
5155
5156L2TPv2 FDIR rules can be created by the following commands::
5157
5158   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 type control
5159            session_id is 0x1111 / end actions queue index 3 / end
5160   testpmd> flow create 0 ingress pattern eth src is 00:00:00:00:00:01 / ipv4
5161            / udp / l2tpv2 type data / end actions queue index 3 / end
5162   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 type data
5163            session_id is 0x1111 / ppp / end actions queue index 3 / end
5164   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 / ppp / ipv4
5165            src is 10.0.0.1 / end actions queue index 3 / end
5166   testpmd> flow create 0 ingress pattern eth / ipv6 / udp / l2tpv2 / ppp / ipv6
5167            dst is ABAB:910B:6666:3457:8295:3333:1800:2929 / end actions queue index 3 / end
5168   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 / ppp / ipv4
5169            / udp src is 22 / end actions queue index 3 / end
5170   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 / ppp / ipv4
5171            / tcp dst is 23 / end actions queue index 3 / end
5172
5173Sample RAW rule
5174~~~~~~~~~~~~~~~
5175
5176A RAW rule can be created as following using ``pattern_hex`` key and mask.
5177
5178::
5179
5180    testpmd> flow create 0 group 0 priority 1 ingress pattern raw relative is 0 search is 0 offset
5181             is 0 limit is 0 pattern_hex spec 00000000000000000000000000000000000000000000000000000a0a0a0a
5182             pattern_hex mask 0000000000000000000000000000000000000000000000000000ffffffff / end actions
5183             queue index 4 / end
5184
5185BPF Functions
5186--------------
5187
5188The following sections show functions to load/unload eBPF based filters.
5189
5190bpf-load
5191~~~~~~~~
5192
5193Load an eBPF program as a callback for particular RX/TX queue::
5194
5195   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5196
5197The available load-flags are:
5198
5199* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5200
5201* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5202
5203* ``-``: none.
5204
5205.. note::
5206
5207   You'll need clang v3.7 or above to build bpf program you'd like to load
5208
5209For example:
5210
5211.. code-block:: console
5212
5213   cd examples/bpf
5214   clang -O2 -target bpf -c t1.c
5215
5216Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5217
5218.. code-block:: console
5219
5220   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5221
5222To load (not JITed) t1.o at TX queue 0, port 0:
5223
5224.. code-block:: console
5225
5226   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5227
5228bpf-unload
5229~~~~~~~~~~
5230
5231Unload previously loaded eBPF program for particular RX/TX queue::
5232
5233   testpmd> bpf-unload rx|tx (portid) (queueid)
5234
5235For example to unload BPF filter from TX queue 0, port 0:
5236
5237.. code-block:: console
5238
5239   testpmd> bpf-unload tx 0 0
5240
5241Flex Item Functions
5242-------------------
5243
5244The following sections show functions that configure and create flex item object,
5245create flex pattern and use it in a flow rule.
5246The commands will use 20 bytes IPv4 header for examples:
5247
5248::
5249
5250   0                   1                   2                   3

5265Create flex item
5266~~~~~~~~~~~~~~~~
5267
5268Flex item object is created by PMD according to a new header configuration. The
5269header configuration is compiled by the testpmd and stored in
5270``rte_flow_item_flex_conf`` type variable.
5271
5272::
5273
5274   # flow flex_item create <port> <flex id> <configuration file>
5275   testpmd> flow flex_item init 0 3 ipv4_flex_config.json
5276   port-0: created flex item #3
5277
5278Flex item configuration is kept in external JSON file.
5279It describes the following header elements:
5280
5281**New header length.**
5282
5283Specify whether the new header has fixed or variable length and the basic/minimal
5284header length value.
5285
5286If header length is not fixed, header location with a value that completes header
5287length calculation and scale/offset function must be added.
5288
5289Scale function depends on port hardware.
5290
5291**Next protocol.**
5292
5293Describes location in the new header that specify following network header type.
5294
5295**Flow match samples.**
5296
5297Describes locations in the new header that will be used in flow rules.
5298
5299Number of flow samples and sample maximal length depend of port hardware.
5300
5301**Input trigger.**
5302
5303Describes preceding network header configuration.
5304
5305**Output trigger.**
5306
5307Describes conditions that trigger transfer to following network header
5308
5309.. code-block:: json
5310

5331
5332Flex pattern and flow rules
5333~~~~~~~~~~~~~~~~~~~~~~~~~~~
5334
5335Flex pattern describe parts of network header that will trigger flex flow item hit in a flow rule.
5336Flex pattern directly related to flex item samples configuration.
5337Flex pattern can be shared between ports.
5338
5339**Flex pattern and flow rule to match IPv4 version and 20 bytes length**
5340
5341::
5342
5343   # set flex_pattern <pattern_id> is <hex bytes sequence>
5344   testpmd> flow flex_item pattern 5 is 45FF
5345   created pattern #5
5346
5347   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 5 / end actions mark id 1 / queue index 0 / end
5348   Flow rule #0 created
5349
5350**Flex pattern and flow rule to match packets with source address 1.2.3.4**
5351
5352::
5353
5354   testpmd> flow flex_item pattern 2 spec 45000000000000000000000001020304 mask FF0000000000000000000000FFFFFFFF
5355   created pattern #2
5356
5357   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 2 / end actions mark id 1 / queue index 0 / end
5358   Flow rule #0 created
