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

108   testpmd>
109
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.

310
311set fwd
312~~~~~~~

314Set the packet forwarding mode::
315
316   testpmd> set fwd (io|mac|macswap|flowgen| \
317                     rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq) (""|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
360* ``shared-rxq``: Receive only for shared Rx queue.
361  Resolve packet source port from mbuf and update stream statistics accordingly.
362
363Example::
364
365   testpmd> set fwd rxonly
366
367   Set rxonly packet forwarding mode
368
369
370show fwd
371~~~~~~~~
372
373When running, forwarding engines maintain statistics from the time they have been started.
374Example for the io forwarding engine, with some packet drops on the tx side::
375
376   testpmd> show fwd stats all
377

651Configuration Functions
652-----------------------
653
654The testpmd application can be configured from the runtime as well as from the command-line.
655
656This section details the available configuration functions that are available.
657
658.. note::
659
660   Configuration changes only become active when forwarding is started/restarted.
661
662set default
663~~~~~~~~~~~
664
665Reset forwarding to the default configuration::
666
667   testpmd> set default
668
669set verbose
670~~~~~~~~~~~
671
672Set the debug verbosity level::
673
674   testpmd> set verbose (level)
675
676Available levels are as following:
677
678* ``0`` silent except for error.
679* ``1`` fully verbose except for Tx packets.
680* ``2`` fully verbose except for Rx packets.
681* ``> 2`` fully verbose.
682
683set log
684~~~~~~~
685
686Set the log level for a log type::
687
688	testpmd> set log global|(type) (level)
689
690Where:
691
692* ``type`` is the log name.
693
694* ``level`` is the log level.
695
696For example, to change the global log level::
697
698	testpmd> set log global (level)
699
700Regexes can also be used for type. To change log level of user1, user2 and user3::
701
702	testpmd> set log user[1-3] (level)
703
704set nbport
705~~~~~~~~~~
706
707Set the number of ports used by the application:
708
709set nbport (num)
710
711This is equivalent to the ``--nb-ports`` command-line option.
712
713set nbcore
714~~~~~~~~~~
715
716Set the number of cores used by the application::
717
718   testpmd> set nbcore (num)
719
720This is equivalent to the ``--nb-cores`` command-line option.
721
722.. note::
723
724   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
725
726set coremask
727~~~~~~~~~~~~
728
729Set the forwarding cores hexadecimal mask::
730
731   testpmd> set coremask (mask)
732
733This is equivalent to the ``--coremask`` command-line option.
734
735.. note::
736
737   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
738
739set portmask
740~~~~~~~~~~~~
741
742Set the forwarding ports hexadecimal mask::
743
744   testpmd> set portmask (mask)
745
746This is equivalent to the ``--portmask`` command-line option.
747
748set record-core-cycles
749~~~~~~~~~~~~~~~~~~~~~~
750
751Set the recording of CPU cycles::
752
753   testpmd> set record-core-cycles (on|off)
754
755Where:
756
757* ``on`` enables measurement of CPU cycles per packet.
758
759* ``off`` disables measurement of CPU cycles per packet.
760
761This is equivalent to the ``--record-core-cycles command-line`` option.
762
763set record-burst-stats
764~~~~~~~~~~~~~~~~~~~~~~
765
766Set the displaying of RX and TX bursts::
767
768   testpmd> set record-burst-stats (on|off)
769
770Where:
771
772* ``on`` enables display of RX and TX bursts.
773
774* ``off`` disables display of RX and TX bursts.
775
776This is equivalent to the ``--record-burst-stats command-line`` option.
777
778set burst
779~~~~~~~~~
780
781Set number of packets per burst::
782
783   testpmd> set burst (num)
784
785This is equivalent to the ``--burst command-line`` option.
786
787When retry is enabled, the transmit delay time and number of retries can also be set::
788
789   testpmd> set burst tx delay (microseconds) retry (num)
790
791set rxoffs
792~~~~~~~~~~
793
794Set the offsets of segments relating to the data buffer beginning on receiving
795if split feature is engaged. Affects only the queues configured with split
796offloads (currently BUFFER_SPLIT is supported only).
797
798   testpmd> set rxoffs (x[,y]*)
799
800Where x[,y]* represents a CSV list of values, without white space. If the list
801of offsets is shorter than the list of segments the zero offsets will be used
802for the remaining segments.
803
804set rxpkts
805~~~~~~~~~~
806
807Set the length of segments to scatter packets on receiving if split
808feature is engaged. Affects only the queues configured with split offloads
809(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
810pools can be specified with --mbuf-size command line parameter and the mbufs
811to receive will be allocated sequentially from these extra memory pools (the
812mbuf for the first segment is allocated from the first pool, the second one
813from the second pool, and so on, if segment number is greater then pool's the
814mbuf for remaining segments will be allocated from the last valid pool).
815
816   testpmd> set rxpkts (x[,y]*)
817
818Where x[,y]* represents a CSV list of values, without white space. Zero value
819means to use the corresponding memory pool data buffer size.
820
821set txpkts
822~~~~~~~~~~
823
824Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
825
826   testpmd> set txpkts (x[,y]*)
827
828Where x[,y]* represents a CSV list of values, without white space.
829
830set txtimes
831~~~~~~~~~~~
832
833Configure the timing burst pattern for Tx only mode. This command enables
834the packet send scheduling on dynamic timestamp mbuf field and configures
835timing pattern in Tx only mode. In this mode, if scheduling is enabled
836application provides timestamps in the packets being sent. It is possible
837to configure delay (in unspecified device clock units) between bursts
838and between the packets within the burst::
839
840   testpmd> set txtimes (inter),(intra)
841
842where:
843
844* ``inter``  is the delay between the bursts in the device clock units.
845  If ``intra`` is zero, this is the time between the beginnings of the
846  first packets in the neighbour bursts, if ``intra`` is not zero,
847  ``inter`` specifies the time between the beginning of the first packet
848  of the current burst and the beginning of the last packet of the
849  previous burst. If ``inter`` parameter is zero the send scheduling
850  on timestamps is disabled (default).
851
852* ``intra`` is the delay between the packets within the burst specified
853  in the device clock units. The number of packets in the burst is defined
854  by regular burst setting. If ``intra`` parameter is zero no timestamps
855  provided in the packets excepting the first one in the burst.
856
857As the result the bursts of packet will be transmitted with specific
858delays between the packets within the burst and specific delay between
859the bursts. The rte_eth_read_clock() must be supported by the device(s)
860and is supposed to be engaged to get the current device clock value
861and provide the reference for the timestamps. If there is no supported
862rte_eth_read_clock() there will be no send scheduling provided on the port.
863
864set txsplit
865~~~~~~~~~~~
866
867Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
868
869   testpmd> set txsplit (off|on|rand)
870
871Where:
872
873* ``off`` disable packet copy & split for CSUM mode.
874
875* ``on`` split outgoing packet into multiple segments. Size of each segment
876  and number of segments per packet is determined by ``set txpkts`` command
877  (see above).
878
879* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
880
881set corelist
882~~~~~~~~~~~~
883
884Set the list of forwarding cores::
885
886   testpmd> set corelist (x[,y]*)
887
888For example, to change the forwarding cores:
889
890.. code-block:: console
891
892   testpmd> set corelist 3,1
893   testpmd> show config fwd
894
895   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
896   Logical Core 3 (socket 0) forwards packets on 1 streams:
897   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
898   Logical Core 1 (socket 0) forwards packets on 1 streams:
899   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
900

915
916   testpmd> set portlist 0,2,1,3
917   testpmd> show config fwd
918
919   io packet forwarding - ports=4 - cores=1 - streams=4
920   Logical Core 3 (socket 0) forwards packets on 4 streams:
921   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
922   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
923   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03

1202csum parse-tunnel
1203~~~~~~~~~~~~~~~~~
1204
1205Define how tunneled packets should be handled by the csum forward
1206engine::
1207
1208   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1209
1210If enabled, the csum forward engine will try to recognize supported
1211tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1212
1213If disabled, treat tunnel packets as non-tunneled packets (a inner
1214header is handled as a packet payload).
1215
1216.. note::
1217
1218   The port argument is the TX port like in the ``csum set`` command.
1219
1220Example:
1221
1222Consider a packet in packet like the following::
1223
1224   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1225
1226* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1227  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1228  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1229
1230* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1231   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1259~~~~~~~~~~~~~~
1260
1261Set tso segment size of tunneled packets for a port in csum engine::
1262
1263   testpmd> tunnel_tso set (tso_segsz) (port_id)
1264
1265tunnel tso show
1266~~~~~~~~~~~~~~~
1267

1269
1270   testpmd> tunnel_tso show (port_id)
1271
1272set port - gro
1273~~~~~~~~~~~~~~
1274
1275Enable or disable GRO in ``csum`` forwarding engine::
1276
1277   testpmd> set port <port_id> gro on|off
1278
1279If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1280packets received from the given port.
1281
1282If disabled, packets received from the given port won't be performed
1283GRO. By default, GRO is disabled for all ports.
1284
1285.. note::
1286
1287   When enable GRO for a port, TCP/IPv4 packets received from the port
1288   will be performed GRO. After GRO, all merged packets have bad
1289   checksums, since the GRO library doesn't re-calculate checksums for
1290   the merged packets. Therefore, if users want the merged packets to
1291   have correct checksums, please select HW IP checksum calculation and
1292   HW TCP checksum calculation for the port which the merged packets are
1293   transmitted to.
1294
1295show port - gro
1296~~~~~~~~~~~~~~~
1297
1298Display GRO configuration for a given port::
1299
1300   testpmd> show port <port_id> gro
1301
1302set gro flush
1303~~~~~~~~~~~~~
1304
1305Set the cycle to flush the GROed packets from reassembly tables::
1306
1307   testpmd> set gro flush <cycles>
1308
1309When enable GRO, the csum forwarding engine performs GRO on received
1310packets, and the GROed packets are stored in reassembly tables. Users
1311can use this command to determine when the GROed packets are flushed
1312from the reassembly tables.
1313
1314The ``cycles`` is measured in GRO operation times. The csum forwarding
1315engine flushes the GROed packets from the tables every ``cycles`` GRO
1316operations.
1317
1318By default, the value of ``cycles`` is 1, which means flush GROed packets
1319from the reassembly tables as soon as one GRO operation finishes. The value
1320of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1321
1322Please note that the large value of ``cycles`` may cause the poor TCP/IP
1323stack performance. Because the GROed packets are delayed to arrive the
1324stack, thus causing more duplicated ACKs and TCP retransmissions.
1325
1326set port - gso
1327~~~~~~~~~~~~~~
1328
1329Toggle per-port GSO support in ``csum`` forwarding engine::
1330
1331   testpmd> set port <port_id> gso on|off
1332
1333If enabled, the csum forwarding engine will perform GSO on supported IPv4
1334packets, transmitted on the given port.
1335
1336If disabled, packets transmitted on the given port will not undergo GSO.
1337By default, GSO is disabled for all ports.
1338
1339.. note::
1340
1341   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1342   port undergo GSO. Afterwards, the segmented packets are represented by
1343   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1344   of checksums for GSO'd segments in SW. As a result, if users want correct
1345   checksums in GSO segments, they should enable HW checksum calculation for
1346   GSO-enabled ports.
1347
1348   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1349   by setting the following options in the csum forwarding engine:
1350
1351   testpmd> csum set outer_ip hw <port_id>
1352
1353   testpmd> csum set ip hw <port_id>
1354
1355   testpmd> csum set tcp hw <port_id>
1356
1357   UDP GSO is the same as IP fragmentation, which treats the UDP header
1358   as the payload and does not modify it during segmentation. That is,
1359   after UDP GSO, only the first output fragment has the original UDP
1360   header. Therefore, users need to enable HW IP checksum calculation
1361   and SW UDP checksum calculation for GSO-enabled ports, if they want
1362   correct checksums for UDP/IPv4 packets.
1363
1364set gso segsz
1365~~~~~~~~~~~~~
1366
1367Set the maximum GSO segment size (measured in bytes), which includes the
1368packet header and the packet payload for GSO-enabled ports (global)::

1972rte_flow_action_raw_encap::
1973
1974 set raw_encap {index} {item} [/ {item} [...]] / end_set
1975
1976There are multiple global buffers for ``raw_encap``, this command will set one
1977internal buffer index by ``{index}``.
1978If there is no ``{index}`` specified::
1979
1980 set raw_encap {item} [/ {item} [...]] / end_set
1981
1982the default index ``0`` is used.

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

2155   EAL:   PCI memory unmapped at 0x7f83bfa80000
2156   Done
2157
2158
2159For example, to detach a virtual device port 0.
2160
2161.. code-block:: console
2162
2163   testpmd> port stop 0
2164   Stopping ports...
2165   Done
2166   testpmd> port close 0
2167   Closing ports...
2168   Done
2169
2170   testpmd> port detach 0
2171   Detaching a port...
2172   PMD: Closing pcap ethdev on numa socket 0
2173   Port 'net_pcap0' is detached. Now total ports is 0
2174   Done
2175
2176To remove a pci device completely from the system, first detach the port from testpmd.
2177Then the device should be moved under kernel management.
2178Finally the device can be removed using kernel pci hotplug functionality.
2179
2180For example, to move a pci device under kernel management:
2181
2182.. code-block:: console
2183
2184   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2185

2261~~~~~~~~~~~~~~~~~~~
2262
2263Set the speed and duplex mode for all ports or a specific port::
2264
2265   testpmd> port config (port_id|all) speed (10|100|1000|10000|25000|40000|50000|100000|200000|auto) \
2266            duplex (half|full|auto)
2267
2268port config - queues/descriptors
2269~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2270
2271Set number of queues/descriptors for rxq, txq, rxd and txd::
2272
2273   testpmd> port config all (rxq|txq|rxd|txd) (value)
2274
2275This is equivalent to the ``--rxq``, ``--txq``, ``--rxd`` and ``--txd`` command-line options.
2276
2277port config - max-pkt-len
2278~~~~~~~~~~~~~~~~~~~~~~~~~
2279

2301
2302Packet dropping when no receive buffers available is off by default.
2303
2304The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2305
2306port config - RSS
2307~~~~~~~~~~~~~~~~~
2308
2309Set the RSS (Receive Side Scaling) mode on or off::

2312
2313RSS is on by default.
2314
2315The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp|l2tpv2.
2316
2317The ``default`` option enables all supported RSS types reported by device info.

2334
2335The traffic class should be 4 or 8.
2336
2337port config - Burst
2338~~~~~~~~~~~~~~~~~~~
2339
2340Set the number of packets per burst::
2341

2425
2426port config dynf
2427~~~~~~~~~~~~~~~~
2428
2429Set/clear dynamic flag per port.
2430testpmd will register this flag in the mbuf (same registration
2431for both Tx and Rx). Then set/clear this flag for each Tx
2432packet sent from this port. The set bit only works for Tx packet::
2433
2434   testpmd> port config (port_id) dynf (name) (set|clear)

2465Device Functions
2466----------------
2467
2468The following sections show functions for device operations.
2469
2470device detach
2471~~~~~~~~~~~~~
2472
2473Detach a device specified by pci address or virtual device args::
2474
2475   testpmd> device detach (identifier)
2476
2477Before detaching a device associated with ports, the ports should be stopped and closed.
2478
2479For example, to detach a pci device whose address is 0002:03:00.0.
2480
2481.. code-block:: console
2482
2483    testpmd> device detach 0002:03:00.0
2484    Removing a device...
2485    Port 1 is now closed
2486    EAL: Releasing pci mapped resource for 0002:03:00.0
2487    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2488    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2489    Device 0002:03:00.0 is detached
2490    Now total ports is 1
2491
2492For example, to detach a port created by pcap PMD.
2493
2494.. code-block:: console
2495
2496    testpmd> device detach net_pcap0
2497    Removing a device...
2498    Port 0 is now closed
2499    Device net_pcap0 is detached
2500    Now total ports is 0
2501    Done
2502
2503In this case, identifier is ``net_pcap0``.
2504This identifier format is the same as ``--vdev`` format of DPDK applications.
2505
2506Link Bonding Functions
2507----------------------
2508
2509The Link Bonding functions make it possible to dynamically create and

2530
2531For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2532
2533   testpmd> add bonding slave 6 10
2534
2535
2536remove bonding slave
2537~~~~~~~~~~~~~~~~~~~~
2538
2539Removes an Ethernet slave device from a Link Bonding device::
2540
2541   testpmd> remove bonding slave (slave id) (port id)
2542
2543For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::

2586
2587For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2588
2589   testpmd> set bonding balance_xmit_policy 10 l34
2590
2591
2592set bonding mon_period
2593~~~~~~~~~~~~~~~~~~~~~~

2596
2597This adds support for PMD slave devices which do not support link status interrupts.
2598When the mon_period is set to a value greater than 0 then all PMD's which do not support
2599link status ISR will be queried every polling interval to check if their link status has changed::
2600
2601   testpmd> set bonding mon_period (port_id) (value)

3295Configure flexible payload selection::
3296
3297   flow_director_flex_payload (port_id) (raw|l2|l3|l4) (config)
3298
3299For example, to select the first 16 bytes from the offset 4 (bytes) of packet's payload as flexible payload::
3300
3301   testpmd> flow_director_flex_payload 0 l4 \
3302            (4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)

3307Flow rules management
3308---------------------
3309
3310Control of the generic flow API (*rte_flow*) is fully exposed through the
3311``flow`` command (validation, creation, destruction, queries and operation
3312modes).
3313
3314Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3315features simultaneously may cause undefined side-effects and is therefore
3316not recommended.
3317
3318``flow`` syntax
3319~~~~~~~~~~~~~~~
3320
3321Because the ``flow`` command uses dynamic tokens to handle the large number
3322of possible flow rules combinations, its behavior differs slightly from
3323other commands, in particular:
3324
3325- Pressing *?* or the *<tab>* key displays contextual help for the current
3326  token, not that of the entire command.
3327
3328- Optional and repeated parameters are supported (provided they are listed
3329  in the contextual help).
3330
3331The first parameter stands for the operation mode. Possible operations and
3332their general syntax are described below. They are covered in detail in the
3333following sections.
3334
3335- Check whether a flow rule can be created::
3336
3337   flow validate {port_id}
3338       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3339       pattern {item} [/ {item} [...]] / end
3340       actions {action} [/ {action} [...]] / end
3341
3342- Create a flow rule::
3343
3344   flow create {port_id}
3345       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3346       pattern {item} [/ {item} [...]] / end
3347       actions {action} [/ {action} [...]] / end
3348
3349- Destroy specific flow rules::
3350
3351   flow destroy {port_id} rule {rule_id} [...]
3352
3353- Destroy all flow rules::
3354
3355   flow flush {port_id}
3356
3357- Query an existing flow rule::
3358
3359   flow query {port_id} {rule_id} {action}
3360
3361- List existing flow rules sorted by priority, filtered by group
3362  identifiers::
3363
3364   flow list {port_id} [group {group_id}] [...]
3365
3366- Restrict ingress traffic to the defined flow rules::
3367
3368   flow isolate {port_id} {boolean}
3369
3370- Dump internal representation information of all flows in hardware::
3371
3372   flow dump {port_id} all {output_file}
3373
3374  for one flow::
3375
3376   flow dump {port_id} rule {rule_id} {output_file}
3377
3378- List and destroy aged flow rules::
3379
3380   flow aged {port_id} [destroy]
3381
3382- Tunnel offload - create a tunnel stub::
3383
3384   flow tunnel create {port_id} type {tunnel_type}
3385
3386- Tunnel offload - destroy a tunnel stub::
3387
3388   flow tunnel destroy {port_id} id {tunnel_id}
3389
3390- Tunnel offload - list port tunnel stubs::
3391
3392   flow tunnel list {port_id}
3393
3394Creating a tunnel stub for offload
3395~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3396
3397``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3398
3399   flow tunnel create {port_id} type {tunnel_type}
3400
3401If successful, it will return a tunnel stub ID usable with other commands::
3402
3403   port [...]: flow tunnel #[...] type [...]
3404
3405Tunnel stub ID is relative to a port.
3406
3407Destroying tunnel offload stub
3408~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3409
3410``flow tunnel destroy`` destroy port tunnel stub::
3411
3412   flow tunnel destroy {port_id} id {tunnel_id}
3413
3414Listing tunnel offload stubs
3415~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3416
3417``flow tunnel list`` list port tunnel offload stubs::
3418
3419   flow tunnel list {port_id}
3420
3421Validating flow rules
3422~~~~~~~~~~~~~~~~~~~~~
3423
3424``flow validate`` reports whether a flow rule would be accepted by the
3425underlying device in its current state but stops short of creating it. It is
3426bound to ``rte_flow_validate()``::
3427
3428   flow validate {port_id}
3429      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3430      pattern {item} [/ {item} [...]] / end
3431      actions {action} [/ {action} [...]] / end
3432
3433If successful, it will show::
3434
3435   Flow rule validated
3436
3437Otherwise it will show an error message of the form::
3438
3439   Caught error type [...] ([...]): [...]
3440
3441This command uses the same parameters as ``flow create``, their format is
3442described in `Creating flow rules`_.
3443
3444Check whether redirecting any Ethernet packet received on port 0 to RX queue
3445index 6 is supported::
3446
3447   testpmd> flow validate 0 ingress pattern eth / end
3448      actions queue index 6 / end
3449   Flow rule validated
3450   testpmd>
3451
3452Port 0 does not support TCPv6 rules::
3453
3454   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3455      actions drop / end
3456   Caught error type 9 (specific pattern item): Invalid argument
3457   testpmd>
3458
3459Creating flow rules
3460~~~~~~~~~~~~~~~~~~~
3461
3462``flow create`` validates and creates the specified flow rule. It is bound
3463to ``rte_flow_create()``::
3464
3465   flow create {port_id}
3466      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3467      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3468      pattern {item} [/ {item} [...]] / end
3469      actions {action} [/ {action} [...]] / end
3470
3471If successful, it will return a flow rule ID usable with other commands::
3472
3473   Flow rule #[...] created
3474
3475Otherwise it will show an error message of the form::
3476
3477   Caught error type [...] ([...]): [...]
3478
3479Parameters describe in the following order:
3480
3481- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3482- Tunnel offload specification (tunnel_set, tunnel_match)
3483- A matching pattern, starting with the *pattern* token and terminated by an
3484  *end* pattern item.
3485- Actions, starting with the *actions* token and terminated by an *end*
3486  action.
3487
3488These translate directly to *rte_flow* objects provided as-is to the
3489underlying functions.
3490
3491The shortest valid definition only comprises mandatory tokens::
3492
3493   testpmd> flow create 0 pattern end actions end
3494
3495Note that PMDs may refuse rules that essentially do nothing such as this
3496one.
3497
3498**All unspecified object values are automatically initialized to 0.**
3499
3500Attributes
3501^^^^^^^^^^
3502
3503These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3504specified before the ``pattern`` token.
3505
3506- ``group {group id}``: priority group.
3507- ``priority {level}``: priority level within group.
3508- ``ingress``: rule applies to ingress traffic.
3509- ``egress``: rule applies to egress traffic.
3510- ``transfer``: apply rule directly to endpoints found in pattern.
3511
3512Please note that use of ``transfer`` attribute requires that the flow and
3513its indirect components be managed via so-called ``transfer`` proxy port.
3514See `show flow transfer proxy port ID for the given port`_ for details.
3515
3516Each instance of an attribute specified several times overrides the previous
3517value as shown below (group 4 is used)::
3518
3519   testpmd> flow create 0 group 42 group 24 group 4 [...]
3520
3521Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3522
3523While not specifying a direction is an error, some rules may allow both
3524simultaneously.
3525
3526Most rules affect RX therefore contain the ``ingress`` token::
3527
3528   testpmd> flow create 0 ingress pattern [...]
3529
3530Tunnel offload
3531^^^^^^^^^^^^^^
3532
3533Indicate tunnel offload rule type
3534
3535- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3536- ``tunnel_match {tunnel_id}``:  mark rule as tunnel offload match type.
3537
3538Matching pattern
3539^^^^^^^^^^^^^^^^
3540
3541A matching pattern starts after the ``pattern`` token. It is made of pattern
3542items and is terminated by a mandatory ``end`` item.
3543
3544Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3545rte_flow_item_type``).
3546
3547The ``/`` token is used as a separator between pattern items as shown
3548below::
3549
3550   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3551
3552Note that protocol items like these must be stacked from lowest to highest
3553layer to make sense. For instance, the following rule is either invalid or
3554unlikely to match any packet::
3555
3556   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3557
3558More information on these restrictions can be found in the *rte_flow*
3559documentation.
3560
3561Several items support additional specification structures, for example
3562``ipv4`` allows specifying source and destination addresses as follows::
3563
3564   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3565      dst is 10.2.0.0 / end [...]
3566
3567This rule matches all IPv4 traffic with the specified properties.
3568
3569In this example, ``src`` and ``dst`` are field names of the underlying
3570``struct rte_flow_item_ipv4`` object. All item properties can be specified
3571in a similar fashion.
3572
3573The ``is`` token means that the subsequent value must be matched exactly,
3574and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3575accordingly. Possible assignment tokens are:
3576
3577- ``is``: match value perfectly (with full bit-mask).
3578- ``spec``: match value according to configured bit-mask.
3579- ``last``: specify upper bound to establish a range.
3580- ``mask``: specify bit-mask with relevant bits set to one.
3581- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3582
3583These yield identical results::
3584
3585   ipv4 src is 10.1.1.1
3586
3587::
3588
3589   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3590
3591::
3592
3593   ipv4 src spec 10.1.1.1 src prefix 32
3594
3595::
3596
3597   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3598
3599::
3600
3601   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3602
3603Inclusive ranges can be defined with ``last``::
3604
3605   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3606
3607Note that ``mask`` affects both ``spec`` and ``last``::
3608
3609   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3610      # matches 10.1.0.0 to 10.2.255.255
3611
3612Properties can be modified multiple times::
3613
3614   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3615
3616::
3617
3618   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3874Actions list
3875^^^^^^^^^^^^
3876
3877A list of actions starts after the ``actions`` token in the same fashion as
3878`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3879terminated by a mandatory ``end`` action.
3880
3881Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3882rte_flow_action_type``).
3883
3884Dropping all incoming UDPv4 packets can be expressed as follows::
3885
3886   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3887      actions drop / end
3888
3889Several actions have configurable properties which must be specified when
3890there is no valid default value. For example, ``queue`` requires a target
3891queue index.
3892
3893This rule redirects incoming UDPv4 traffic to queue index 6::
3894
3895   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3896      actions queue index 6 / end
3897
3898While this one could be rejected by PMDs (unspecified queue index)::
3899
3900   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3901      actions queue / end
3902
3903As defined by *rte_flow*, the list is not ordered, all actions of a given
3904rule are performed simultaneously. These are equivalent::
3905
3906   queue index 6 / void / mark id 42 / end
3907
3908::
3909
3910   void / mark id 42 / queue index 6 / end
3911
3912All actions in a list should have different types, otherwise only the last
3913action of a given type is taken into account::
3914
3915   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3916
3917::
3918
3919   drop / drop / drop / end # drop is performed only once
3920
3921::
3922
3923   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3924
3925Considering they are performed simultaneously, opposite and overlapping
3926actions can sometimes be combined when the end result is unambiguous::
3927
3928   drop / queue index 6 / end # drop has no effect
3929
3930::
3931
3932   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3933
3934::
3935
3936   drop / passthru / end # drop has no effect
3937
3938Note that PMDs may still refuse such combinations.

4159Destroying flow rules
4160~~~~~~~~~~~~~~~~~~~~~
4161
4162``flow destroy`` destroys one or more rules from their rule ID (as returned
4163by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4164times as necessary::
4165
4166   flow destroy {port_id} rule {rule_id} [...]
4167
4168If successful, it will show::
4169
4170   Flow rule #[...] destroyed
4171
4172It does not report anything for rule IDs that do not exist. The usual error
4173message is shown when a rule cannot be destroyed::
4174
4175   Caught error type [...] ([...]): [...]
4176
4177``flow flush`` destroys all rules on a device and does not take extra
4178arguments. It is bound to ``rte_flow_flush()``::
4179
4180   flow flush {port_id}
4181
4182Any errors are reported as above.
4183
4184Creating several rules and destroying them::
4185
4186   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4187      actions queue index 2 / end
4188   Flow rule #0 created
4189   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4190      actions queue index 3 / end
4191   Flow rule #1 created
4192   testpmd> flow destroy 0 rule 0 rule 1
4193   Flow rule #1 destroyed
4194   Flow rule #0 destroyed
4195   testpmd>
4196
4197The same result can be achieved using ``flow flush``::
4198
4199   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4200      actions queue index 2 / end
4201   Flow rule #0 created
4202   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4203      actions queue index 3 / end
4204   Flow rule #1 created
4205   testpmd> flow flush 0
4206   testpmd>
4207
4208Non-existent rule IDs are ignored::
4209
4210   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4211      actions queue index 2 / end
4212   Flow rule #0 created
4213   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4214      actions queue index 3 / end
4215   Flow rule #1 created
4216   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4217   testpmd>
4218   testpmd> flow destroy 0 rule 0
4219   Flow rule #0 destroyed
4220   testpmd>
4221
4222Querying flow rules
4223~~~~~~~~~~~~~~~~~~~
4224
4225``flow query`` queries a specific action of a flow rule having that
4226ability. Such actions collect information that can be reported using this
4227command. It is bound to ``rte_flow_query()``::
4228
4229   flow query {port_id} {rule_id} {action}
4230
4231If successful, it will display either the retrieved data for known actions
4232or the following message::
4233
4234   Cannot display result for action type [...] ([...])
4235
4236Otherwise, it will complain either that the rule does not exist or that some
4237error occurred::
4238
4239   Flow rule #[...] not found
4240
4241::
4242
4243   Caught error type [...] ([...]): [...]
4244
4245Currently only the ``count`` action is supported. This action reports the
4246number of packets that hit the flow rule and the total number of bytes. Its
4247output has the following format::
4248
4249   count:
4250    hits_set: [...] # whether "hits" contains a valid value
4251    bytes_set: [...] # whether "bytes" contains a valid value
4252    hits: [...] # number of packets
4253    bytes: [...] # number of bytes
4254
4255Querying counters for TCPv6 packets redirected to queue 6::
4256
4257   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4258      actions queue index 6 / count / end
4259   Flow rule #4 created
4260   testpmd> flow query 0 4 count
4261   count:
4262    hits_set: 1
4263    bytes_set: 0
4264    hits: 386446
4265    bytes: 0
4266   testpmd>
4267
4268Listing flow rules
4269~~~~~~~~~~~~~~~~~~
4270
4271``flow list`` lists existing flow rules sorted by priority and optionally
4272filtered by group identifiers::
4273
4274   flow list {port_id} [group {group_id}] [...]
4275
4276This command only fails with the following message if the device does not
4277exist::
4278
4279   Invalid port [...]
4280
4281Output consists of a header line followed by a short description of each
4282flow rule, one per line. There is no output at all when no flow rules are
4283configured on the device::
4284
4285   ID      Group   Prio    Attr    Rule
4286   [...]   [...]   [...]   [...]   [...]
4287
4288``Attr`` column flags:
4289
4290- ``i`` for ``ingress``.
4291- ``e`` for ``egress``.
4292
4293Creating several flow rules and listing them::
4294
4295   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4296      actions queue index 6 / end
4297   Flow rule #0 created
4298   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4299      actions queue index 2 / end
4300   Flow rule #1 created
4301   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4302      actions rss queues 6 7 8 end / end
4303   Flow rule #2 created
4304   testpmd> flow list 0
4305   ID      Group   Prio    Attr    Rule
4306   0       0       0       i-      ETH IPV4 => QUEUE

4308   2       0       5       i-      ETH IPV4 UDP => RSS
4309   testpmd>
4310
4311Rules are sorted by priority (i.e. group ID first, then priority level)::
4312
4313   testpmd> flow list 1
4314   ID      Group   Prio    Attr    Rule
4315   0       0       0       i-      ETH => COUNT
4316   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4317   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4318   1       24      0       i-      ETH IPV4 UDP => QUEUE
4319   4       24      10      i-      ETH IPV4 TCP => DROP
4320   3       24      20      i-      ETH IPV4 => DROP

4323   testpmd>
4324
4325Output can be limited to specific groups::
4326
4327   testpmd> flow list 1 group 0 group 63
4328   ID      Group   Prio    Attr    Rule

4335Toggling isolated mode
4336~~~~~~~~~~~~~~~~~~~~~~
4337
4338``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4339must only be injected from the defined flow rules; that no default traffic
4340is expected outside those rules and the driver is free to assign more
4341resources to handle them. It is bound to ``rte_flow_isolate()``::
4342
4343 flow isolate {port_id} {boolean}
4344
4345If successful, enabling or disabling isolated mode shows either::
4346
4347 Ingress traffic on port [...]
4348    is now restricted to the defined flow rules
4349
4350Or::
4351
4352 Ingress traffic on port [...]
4353    is not restricted anymore to the defined flow rules
4354
4355Otherwise, in case of error::
4356
4357   Caught error type [...] ([...]): [...]
4358
4359Mainly due to its side effects, PMDs supporting this mode may not have the
4360ability to toggle it more than once without reinitializing affected ports
4361first (e.g. by exiting testpmd).
4362
4363Enabling isolated mode::
4364
4365 testpmd> flow isolate 0 true
4366 Ingress traffic on port 0 is now restricted to the defined flow rules
4367 testpmd>
4368
4369Disabling isolated mode::
4370
4371 testpmd> flow isolate 0 false
4372 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4373 testpmd>
4374
4375Dumping HW internal information
4376~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4377
4378``flow dump`` dumps the hardware's internal representation information of
4379all flows. It is bound to ``rte_flow_dev_dump()``::
4380
4381   flow dump {port_id} {output_file}
4382
4383If successful, it will show::
4384
4385   Flow dump finished
4386
4387Otherwise, it will complain error occurred::
4388
4389   Caught error type [...] ([...]): [...]
4390
4391Listing and destroying aged flow rules
4392~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4393
4394``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4395and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4396
4397   flow aged {port_id} [destroy]
4398
4399Listing current aged flow rules::
4400
4401   testpmd> flow aged 0
4402   Port 0 total aged flows: 0
4403   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4404      actions age timeout 5 / queue index 0 /  end
4405   Flow rule #0 created
4406   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4407      actions age timeout 4 / queue index 0 /  end
4408   Flow rule #1 created
4409   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4410      actions age timeout 2 / queue index 0 /  end
4411   Flow rule #2 created
4412   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4413      actions age timeout 3 / queue index 0 /  end
4414   Flow rule #3 created
4415
4416
4417Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4418information, all the aged flows are sorted by the longest timeout time. For example, if
4419those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4420will be ID 3, ID 1, ID 0::
4421
4422   testpmd> flow aged 0
4423   Port 0 total aged flows: 4
4424   ID      Group   Prio    Attr
4425   2       0       0       i--
4426   3       0       0       i--
4427   1       0       0       i--
4428   0       0       0       i--
4429
4430If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.
4431
4432   testpmd> flow aged 0 destroy
4433   Port 0 total aged flows: 4
4434   ID      Group   Prio    Attr
4435   2       0       0       i--
4436   3       0       0       i--
4437   1       0       0       i--
4438   0       0       0       i--
4439
4440   Flow rule #2 destroyed
4441   Flow rule #3 destroyed
4442   Flow rule #1 destroyed
4443   Flow rule #0 destroyed
4444   4 flows be destroyed
4445   testpmd> flow aged 0
4446   Port 0 total aged flows: 0
4447
4448Creating indirect actions
4449~~~~~~~~~~~~~~~~~~~~~~~~~
4450
4451``flow indirect_action {port_id} create`` creates indirect action with optional
4452indirect action ID. It is bound to ``rte_flow_action_handle_create()``::
4453
4454   flow indirect_action {port_id} create [action_id {indirect_action_id}]
4455      [ingress] [egress] [transfer] action {action} / end
4456
4457If successful, it will show::
4458
4459   Indirect action #[...] created
4460
4461Otherwise, it will complain either that indirect action already exists or that
4462some error occurred::
4463
4464   Indirect action #[...] is already assigned, delete it first
4465
4466::
4467
4468   Caught error type [...] ([...]): [...]
4469
4470Create indirect rss action with id 100 to queues 1 and 2 on port 0::
4471
4472   testpmd> flow indirect_action 0 create action_id 100 \
4473      ingress action rss queues 1 2 end / end
4474
4475Create indirect rss action with id assigned by testpmd to queues 1 and 2 on
4476port 0::
4477
4478	testpmd> flow indirect_action 0 create action_id \
4479		ingress action rss queues 0 1 end / end
4480
4481Updating indirect actions
4482~~~~~~~~~~~~~~~~~~~~~~~~~
4483
4484``flow indirect_action {port_id} update`` updates configuration of the indirect
4485action from its indirect action ID (as returned by
4486``flow indirect_action {port_id} create``). It is bound to
4487``rte_flow_action_handle_update()``::
4488
4489   flow indirect_action {port_id} update {indirect_action_id}
4490      action {action} / end
4491
4492If successful, it will show::
4493
4494   Indirect action #[...] updated
4495
4496Otherwise, it will complain either that indirect action not found or that some
4497error occurred::
4498
4499   Failed to find indirect action #[...] on port [...]
4500
4501::
4502
4503   Caught error type [...] ([...]): [...]
4504
4505Update indirect rss action having id 100 on port 0 with rss to queues 0 and 3
4506(in create example above rss queues were 1 and 2)::
4507
4508   testpmd> flow indirect_action 0 update 100 action rss queues 0 3 end / end
4509
4510Destroying indirect actions
4511~~~~~~~~~~~~~~~~~~~~~~~~~~~
4512
4513``flow indirect_action {port_id} destroy`` destroys one or more indirect actions
4514from their indirect action IDs (as returned by
4515``flow indirect_action {port_id} create``). It is bound to
4516``rte_flow_action_handle_destroy()``::
4517
4518   flow indirect_action {port_id} destroy action_id {indirect_action_id} [...]
4519
4520If successful, it will show::
4521
4522   Indirect action #[...] destroyed
4523
4524It does not report anything for indirect action IDs that do not exist.
4525The usual error message is shown when a indirect action cannot be destroyed::
4526
4527   Caught error type [...] ([...]): [...]
4528
4529Destroy indirect actions having id 100 & 101::
4530
4531   testpmd> flow indirect_action 0 destroy action_id 100 action_id 101
4532
4533Query indirect actions
4534~~~~~~~~~~~~~~~~~~~~~~
4535
4536``flow indirect_action {port_id} query`` queries the indirect action from its
4537indirect action ID (as returned by ``flow indirect_action {port_id} create``).
4538It is bound to ``rte_flow_action_handle_query()``::
4539
4540  flow indirect_action {port_id} query {indirect_action_id}
4541
4542Currently only rss indirect action supported. If successful, it will show::
4543
4544   Indirect RSS action:
4545      refs:[...]
4546
4547Otherwise, it will complain either that indirect action not found or that some
4548error occurred::
4549
4550   Failed to find indirect action #[...] on port [...]
4551
4552::
4553
4554   Caught error type [...] ([...]): [...]
4555
4556Query indirect action having id 100::
4557
4558   testpmd> flow indirect_action 0 query 100
4559
4560Sample QinQ flow rules
4561~~~~~~~~~~~~~~~~~~~~~~
4562
4563Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4564
4565   testpmd> port stop 0
4566   testpmd> vlan set extend on 0
4567
4568The above command sets the inner and outer TPID's to 0x8100.
4569
4570To change the TPID's the following commands should be used::
4571
4572   testpmd> vlan set outer tpid 0x88A8 0
4573   testpmd> vlan set inner tpid 0x8100 0
4574   testpmd> port start 0
4575
4576Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4577
4578::
4579
4580   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4581       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4582   Flow rule #0 validated

4608
4609Sample VXLAN flow rules
4610~~~~~~~~~~~~~~~~~~~~~~~
4611
4612Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4613filter on a port::
4614
4615  testpmd> rx_vxlan_port add 4789 0
4616
4617Create VXLAN rules on port 0 to steer traffic to PF queues.

5157bpf-load
5158~~~~~~~~
5159
5160Load an eBPF program as a callback for particular RX/TX queue::
5161
5162   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5163
5164The available load-flags are:
5165
5166* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5167
5168* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5169
5170* ``-``: none.
5171
5172.. note::
5173
5174   You'll need clang v3.7 or above to build bpf program you'd like to load
5175
5176For example:
5177
5178.. code-block:: console
5179
5180   cd examples/bpf
5181   clang -O2 -target bpf -c t1.c
5182
5183Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5184
5185.. code-block:: console
5186
5187   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5188
5189To load (not JITed) t1.o at TX queue 0, port 0:
5190
5191.. code-block:: console
5192
5193   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5194
5195bpf-unload
5196~~~~~~~~~~
5197
5198Unload previously loaded eBPF program for particular RX/TX queue::
5199
5200   testpmd> bpf-unload rx|tx (portid) (queueid)
5201
5202For example to unload BPF filter from TX queue 0, port 0:
5203
5204.. code-block:: console
5205
5206   testpmd> bpf-unload tx 0 0
5207
5208Flex Item Functions
5209-------------------
5210
5211The following sections show functions that configure and create flex item object,
5212create flex pattern and use it in a flow rule.
5213The commands will use 20 bytes IPv4 header for examples:
5214
5215::
5216
5217   0                   1                   2                   3

5232Create flex item
5233~~~~~~~~~~~~~~~~
5234
5235Flex item object is created by PMD according to a new header configuration. The
5236header configuration is compiled by the testpmd and stored in
5237``rte_flow_item_flex_conf`` type variable.
5238
5239::
5240
5241   # flow flex_item create <port> <flex id> <configuration file>
5242   testpmd> flow flex_item init 0 3 ipv4_flex_config.json
5243   port-0: created flex item #3
5244
5245Flex item configuration is kept in external JSON file.
5246It describes the following header elements:
5247
5248**New header length.**
5249
5250Specify whether the new header has fixed or variable length and the basic/minimal
5251header length value.
5252
5253If header length is not fixed, header location with a value that completes header
5254length calculation and scale/offset function must be added.
5255
5256Scale function depends on port hardware.
5257
5258**Next protocol.**
5259
5260Describes location in the new header that specify following network header type.
5261
5262**Flow match samples.**
5263
5264Describes locations in the new header that will be used in flow rules.
5265
5266Number of flow samples and sample maximal length depend of port hardware.
5267
5268**Input trigger.**
5269
5270Describes preceding network header configuration.
5271
5272**Output trigger.**
5273
5274Describes conditions that trigger transfer to following network header
5275
5276.. code-block:: json

5299Flex pattern and flow rules
5300~~~~~~~~~~~~~~~~~~~~~~~~~~~
5301
5302Flex pattern describe parts of network header that will trigger flex flow item hit in a flow rule.
5303Flex pattern directly related to flex item samples configuration.
5304Flex pattern can be shared between ports.
5305
5306**Flex pattern and flow rule to match IPv4 version and 20 bytes length**
5307
5308::
5309
5310   # set flex_pattern <pattern_id> is <hex bytes sequence>
5311   testpmd> flow flex_item pattern 5 is 45FF
5312   created pattern #5
5313
5314   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
5315   Flow rule #0 created
5316
5317**Flex pattern and flow rule to match packets with source address 1.2.3.4**
5318
5319::
5320
5321   testpmd> flow flex_item pattern 2 spec 45000000000000000000000001020304 mask FF0000000000000000000000FFFFFFFF
