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|stat_qmap|dcb_tc X
28       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc all
29       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc X
30       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc 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.

61
62Command File Functions
63----------------------
64
65To facilitate loading large number of commands or to avoid cutting and pasting where not
66practical or possible testpmd supports alternative methods for executing commands.
67
68* If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
69  will execute all CLI commands contained within the file immediately before
70  starting packet forwarding or entering interactive mode.
71
72.. code-block:: console
73
74   ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

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

274
275show config
276~~~~~~~~~~~
277
278Displays the configuration of the application.
279The configuration comes from the command-line, the runtime or the application defaults::
280
281   testpmd> show config (rxtx|cores|fwd|rxoffs|rxpkts|txpkts|txtimes)

294
295* ``txpkts``: Packets to TX configuration.
296
297* ``txtimes``: Burst time pattern for Tx only mode.
298
299For example:
300
301.. code-block:: console
302
303   testpmd> show config rxtx
304
305   io packet forwarding - CRC stripping disabled - packets/burst=16
306   nb forwarding cores=2 - nb forwarding ports=1
307   RX queues=1 - RX desc=128 - RX free threshold=0
308   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
309   TX queues=1 - TX desc=512 - TX free threshold=0
310   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
311   TX RS bit threshold=0 - TXQ flags=0x0
312
313set fwd
314~~~~~~~
315
316Set the packet forwarding mode::
317
318   testpmd> set fwd (io|mac|macswap|flowgen| \
319                     rxonly|txonly|csum|icmpecho|noisy|5tswap) (""|retry)
320
321``retry`` can be specified for forwarding engines except ``rx_only``.
322
323The available information categories are:
324
325* ``io``: Forwards packets "as-is" in I/O mode.
326  This is the fastest possible forwarding operation as it does not access packets data.
327  This is the default mode.
328
329* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
330  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
331  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
332  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
333
334* ``macswap``: MAC swap forwarding mode.
335  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
336
337* ``flowgen``: Multi-flow generation mode.
338  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
339
340* ``rxonly``: Receives packets but doesn't transmit them.
341
342* ``txonly``: Generates and transmits packets without receiving any.
343
344* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
345
346* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
347
348* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
349
350* ``noisy``: Noisy neighbor simulation.
351  Simulate more realistic behavior of a guest machine engaged in receiving
352  and sending packets performing Virtual Network Function (VNF).
353
354* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
355
356  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
357
358  L3 swaps the source address and destination address of IP (v4 and v6).
359
360  L4 swaps the source port and destination port of transport layer (TCP and UDP).
361
362Example::
363
364   testpmd> set fwd rxonly
365
366   Set rxonly packet forwarding mode
367
368
369show fwd
370~~~~~~~~
371
372When running, forwarding engines maintain statistics from the time they have been started.
373Example for the io forwarding engine, with some packet drops on the tx side::
374
375   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
673set log
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 txpkts
812~~~~~~~~~~
813
814Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
815
816   testpmd> set txpkts (x[,y]*)
817
818Where x[,y]* represents a CSV list of values, without white space.
819
820set txtimes
821~~~~~~~~~~~
822
823Configure the timing burst pattern for Tx only mode. This command enables
824the packet send scheduling on dynamic timestamp mbuf field and configures
825timing pattern in Tx only mode. In this mode, if scheduling is enabled
826application provides timestamps in the packets being sent. It is possible
827to configure delay (in unspecified device clock units) between bursts
828and between the packets within the burst::
829
830   testpmd> set txtimes (inter),(intra)
831
832where:
833
834* ``inter``  is the delay between the bursts in the device clock units.
835  If ``intra`` is zero, this is the time between the beginnings of the
836  first packets in the neighbour bursts, if ``intra`` is not zero,
837  ``inter`` specifies the time between the beginning of the first packet
838  of the current burst and the beginning of the last packet of the
839  previous burst. If ``inter`` parameter is zero the send scheduling
840  on timestamps is disabled (default).
841
842* ``intra`` is the delay between the packets within the burst specified
843  in the device clock units. The number of packets in the burst is defined
844  by regular burst setting. If ``intra`` parameter is zero no timestamps
845  provided in the packets excepting the first one in the burst.
846
847As the result the bursts of packet will be transmitted with specific
848delays between the packets within the burst and specific delay between
849the bursts. The rte_eth_read_clock() must be supported by the device(s)
850and is supposed to be engaged to get the current device clock value
851and provide the reference for the timestamps. If there is no supported
852rte_eth_read_clock() there will be no send scheduling provided on the port.
853
854set txsplit
855~~~~~~~~~~~
856
857Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
858
859   testpmd> set txsplit (off|on|rand)
860
861Where:
862
863* ``off`` disable packet copy & split for CSUM mode.
864
865* ``on`` split outgoing packet into multiple segments. Size of each segment
866  and number of segments per packet is determined by ``set txpkts`` command
867  (see above).
868
869* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
870
871set corelist
872~~~~~~~~~~~~
873
874Set the list of forwarding cores::
875
876   testpmd> set corelist (x[,y]*)
877
878For example, to change the forwarding cores:
879
880.. code-block:: console
881
882   testpmd> set corelist 3,1
883   testpmd> show config fwd
884
885   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
886   Logical Core 3 (socket 0) forwards packets on 1 streams:
887   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
888   Logical Core 1 (socket 0) forwards packets on 1 streams:
889   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
890
891.. note::

895set portlist
896~~~~~~~~~~~~
897
898Set the list of forwarding ports::
899
900   testpmd> set portlist (x[,y]*)

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

1174
1175* ``on``: is just an enable function which server for other configuration,
1176  it is for all configuration about queue region from up layer,
1177  at first will only keep in DPDK software stored in driver,
1178  only after "flush on", it commit all configuration to HW.

1181  and restore all to DPDK i40e driver default config when start up.
1182
1183Show all queue region related configuration info on a port::
1184
1185   testpmd> show port (port_id) queue-region
1186

1191
1192csum parse-tunnel
1193~~~~~~~~~~~~~~~~~
1194
1195Define how tunneled packets should be handled by the csum forward
1196engine::
1197
1198   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1199
1200If enabled, the csum forward engine will try to recognize supported
1201tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1202
1203If disabled, treat tunnel packets as non-tunneled packets (a inner
1204header is handled as a packet payload).
1205
1206.. note::
1207
1208   The port argument is the TX port like in the ``csum set`` command.
1209
1210Example:
1211
1212Consider a packet in packet like the following::
1213
1214   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1215
1216* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1217  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1218  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1219
1220* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1221   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1262set port - gro
1263~~~~~~~~~~~~~~
1264
1265Enable or disable GRO in ``csum`` forwarding engine::
1266
1267   testpmd> set port <port_id> gro on|off
1268
1269If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1270packets received from the given port.
1271
1272If disabled, packets received from the given port won't be performed
1273GRO. By default, GRO is disabled for all ports.
1274
1275.. note::
1276
1277   When enable GRO for a port, TCP/IPv4 packets received from the port
1278   will be performed GRO. After GRO, all merged packets have bad
1279   checksums, since the GRO library doesn't re-calculate checksums for
1280   the merged packets. Therefore, if users want the merged packets to
1281   have correct checksums, please select HW IP checksum calculation and
1282   HW TCP checksum calculation for the port which the merged packets are
1283   transmitted to.
1284
1285show port - gro
1286~~~~~~~~~~~~~~~
1287
1288Display GRO configuration for a given port::
1289
1290   testpmd> show port <port_id> gro
1291
1292set gro flush
1293~~~~~~~~~~~~~
1294
1295Set the cycle to flush the GROed packets from reassembly tables::
1296
1297   testpmd> set gro flush <cycles>
1298
1299When enable GRO, the csum forwarding engine performs GRO on received
1300packets, and the GROed packets are stored in reassembly tables. Users
1301can use this command to determine when the GROed packets are flushed
1302from the reassembly tables.
1303
1304The ``cycles`` is measured in GRO operation times. The csum forwarding
1305engine flushes the GROed packets from the tables every ``cycles`` GRO
1306operations.
1307
1308By default, the value of ``cycles`` is 1, which means flush GROed packets
1309from the reassembly tables as soon as one GRO operation finishes. The value
1310of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1311
1312Please note that the large value of ``cycles`` may cause the poor TCP/IP
1313stack performance. Because the GROed packets are delayed to arrive the
1314stack, thus causing more duplicated ACKs and TCP retransmissions.
1315
1316set port - gso
1317~~~~~~~~~~~~~~
1318
1319Toggle per-port GSO support in ``csum`` forwarding engine::
1320
1321   testpmd> set port <port_id> gso on|off
1322
1323If enabled, the csum forwarding engine will perform GSO on supported IPv4
1324packets, transmitted on the given port.
1325
1326If disabled, packets transmitted on the given port will not undergo GSO.
1327By default, GSO is disabled for all ports.
1328
1329.. note::
1330
1331   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1332   port undergo GSO. Afterwards, the segmented packets are represented by
1333   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1334   of checksums for GSO'd segments in SW. As a result, if users want correct
1335   checksums in GSO segments, they should enable HW checksum calculation for
1336   GSO-enabled ports.
1337
1338   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1339   by setting the following options in the csum forwarding engine:
1340
1341   testpmd> csum set outer_ip hw <port_id>
1342
1343   testpmd> csum set ip hw <port_id>
1344
1345   testpmd> csum set tcp hw <port_id>
1346
1347   UDP GSO is the same as IP fragmentation, which treats the UDP header
1348   as the payload and does not modify it during segmentation. That is,
1349   after UDP GSO, only the first output fragment has the original UDP
1350   header. Therefore, users need to enable HW IP checksum calculation
1351   and SW UDP checksum calculation for GSO-enabled ports, if they want
1352   correct checksums for UDP/IPv4 packets.
1353
1354set gso segsz

1356
1357Set the maximum GSO segment size (measured in bytes), which includes the

1957rte_flow_action_raw_encap::
1958
1959 set raw_encap {index} {item} [/ {item} [...]] / end_set
1960
1961There are multiple global buffers for ``raw_encap``, this command will set one
1962internal buffer index by ``{index}``.
1963If there is no ``{index}`` specified::
1964
1965 set raw_encap {item} [/ {item} [...]] / end_set
1966
1967the default index ``0`` is used.

2025Port Functions
2026--------------
2027
2028The following sections show functions for configuring ports.
2029
2030.. note::
2031
2032   Port configuration changes only become active when forwarding is started/restarted.
2033
2034port attach
2035~~~~~~~~~~~
2036
2037Attach a port specified by pci address or virtual device args::
2038
2039   testpmd> port attach (identifier)
2040
2041To attach a new pci device, the device should be recognized by kernel first.
2042Then it should be moved under DPDK management.
2043Finally the port can be attached to testpmd.
2044
2045For example, to move a pci device using ixgbe under DPDK management:
2046
2047.. code-block:: console
2048
2049   # Check the status of the available devices.
2050   ./usertools/dpdk-devbind.py --status
2051
2052   Network devices using DPDK-compatible driver
2053   ============================================
2054   <none>
2055
2056   Network devices using kernel driver
2057   ===================================
2058   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2059
2060
2061   # Bind the device to igb_uio.
2062   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2063
2064
2065   # Recheck the status of the devices.
2066   ./usertools/dpdk-devbind.py --status
2067   Network devices using DPDK-compatible driver
2068   ============================================
2069   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2070
2071To attach a port created by virtual device, above steps are not needed.
2072
2073For example, to attach a port whose pci address is 0000:0a:00.0.
2074
2075.. code-block:: console
2076
2077   testpmd> port attach 0000:0a:00.0
2078   Attaching a new port...
2079   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2080   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
2081   EAL:   PCI memory mapped at 0x7f83bfa00000
2082   EAL:   PCI memory mapped at 0x7f83bfa80000
2083   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2084   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2085   Port 0 is attached. Now total ports is 1
2086   Done
2087
2088For example, to attach a port created by pcap PMD.
2089
2090.. code-block:: console
2091
2092   testpmd> port attach net_pcap0
2093   Attaching a new port...
2094   PMD: Initializing pmd_pcap for net_pcap0
2095   PMD: Creating pcap-backed ethdev on numa socket 0
2096   Port 0 is attached. Now total ports is 1
2097   Done
2098
2099In this case, identifier is ``net_pcap0``.
2100This identifier format is the same as ``--vdev`` format of DPDK applications.
2101
2102For example, to re-attach a bonded port which has been previously detached,
2103the mode and slave parameters must be given.
2104
2105.. code-block:: console
2106
2107   testpmd> port attach net_bond_0,mode=0,slave=1
2108   Attaching a new port...
2109   EAL: Initializing pmd_bond for net_bond_0
2110   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2111   Port 0 is attached. Now total ports is 1
2112   Done
2113
2114
2115port detach
2116~~~~~~~~~~~
2117
2118Detach a specific port::
2119
2120   testpmd> port detach (port_id)
2121
2122Before detaching a port, the port should be stopped and closed.
2123
2124For example, to detach a pci device port 0.
2125
2126.. code-block:: console
2127
2128   testpmd> port stop 0
2129   Stopping ports...
2130   Done
2131   testpmd> port close 0
2132   Closing ports...
2133   Done
2134
2135   testpmd> port detach 0
2136   Detaching a port...
2137   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2138   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
2139   EAL:   PCI memory unmapped at 0x7f83bfa00000
2140   EAL:   PCI memory unmapped at 0x7f83bfa80000
2141   Done
2142
2143
2144For example, to detach a virtual device port 0.
2145
2146.. code-block:: console
2147
2148   testpmd> port stop 0
2149   Stopping ports...
2150   Done
2151   testpmd> port close 0
2152   Closing ports...
2153   Done
2154
2155   testpmd> port detach 0
2156   Detaching a port...
2157   PMD: Closing pcap ethdev on numa socket 0
2158   Port 'net_pcap0' is detached. Now total ports is 0
2159   Done
2160
2161To remove a pci device completely from the system, first detach the port from testpmd.
2162Then the device should be moved under kernel management.
2163Finally the device can be removed using kernel pci hotplug functionality.
2164
2165For example, to move a pci device under kernel management:
2166
2167.. code-block:: console
2168
2169   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2170
2171   ./usertools/dpdk-devbind.py --status

2253port config - queues/descriptors
2254~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2255
2256Set number of queues/descriptors for rxq, txq, rxd and txd::
2257
2258   testpmd> port config all (rxq|txq|rxd|txd) (value)
2259
2260This is equivalent to the ``--rxq``, ``--txq``, ``--rxd`` and ``--txd`` command-line options.
2261
2262port config - max-pkt-len

2286
2287Packet dropping when no receive buffers available is off by default.
2288
2289The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2290
2291port config - RSS
2292~~~~~~~~~~~~~~~~~
2293
2294Set the RSS (Receive Side Scaling) mode on or off::

2320The traffic class should be 4 or 8.
2321
2322port config - Burst
2323~~~~~~~~~~~~~~~~~~~
2324
2325Set the number of packets per burst::
2326
2327   testpmd> port config all burst (value)

2441Device Functions
2442----------------
2443
2444The following sections show functions for device operations.
2445
2446device detach
2447~~~~~~~~~~~~~
2448
2449Detach a device specified by pci address or virtual device args::
2450
2451   testpmd> device detach (identifier)
2452
2453Before detaching a device associated with ports, the ports should be stopped and closed.
2454
2455For example, to detach a pci device whose address is 0002:03:00.0.
2456
2457.. code-block:: console
2458
2459    testpmd> device detach 0002:03:00.0
2460    Removing a device...
2461    Port 1 is now closed
2462    EAL: Releasing pci mapped resource for 0002:03:00.0
2463    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2464    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2465    Device 0002:03:00.0 is detached
2466    Now total ports is 1
2467
2468For example, to detach a port created by pcap PMD.
2469
2470.. code-block:: console
2471
2472    testpmd> device detach net_pcap0
2473    Removing a device...
2474    Port 0 is now closed
2475    Device net_pcap0 is detached
2476    Now total ports is 0
2477    Done
2478
2479In this case, identifier is ``net_pcap0``.
2480This identifier format is the same as ``--vdev`` format of DPDK applications.
2481

2508
2509   testpmd> add bonding slave 6 10
2510
2511
2512remove bonding slave
2513~~~~~~~~~~~~~~~~~~~~
2514
2515Removes an Ethernet slave device from a Link Bonding device::

2563For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2564
2565   testpmd> set bonding balance_xmit_policy 10 l34
2566
2567
2568set bonding mon_period
2569~~~~~~~~~~~~~~~~~~~~~~

2572
2573This adds support for PMD slave devices which do not support link status interrupts.
2574When the mon_period is set to a value greater than 0 then all PMD's which do not support
2575link status ISR will be queried every polling interval to check if their link status has changed::
2576
2577   testpmd> set bonding mon_period (port_id) (value)
2578
2579For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

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

3792
3793Actions list
3794^^^^^^^^^^^^
3795
3796A list of actions starts after the ``actions`` token in the same fashion as
3797`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3798terminated by a mandatory ``end`` action.
3799
3800Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3801rte_flow_action_type``).
3802
3803Dropping all incoming UDPv4 packets can be expressed as follows::
3804
3805   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3806      actions drop / end
3807
3808Several actions have configurable properties which must be specified when
3809there is no valid default value. For example, ``queue`` requires a target
3810queue index.
3811
3812This rule redirects incoming UDPv4 traffic to queue index 6::
3813
3814   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3815      actions queue index 6 / end
3816
3817While this one could be rejected by PMDs (unspecified queue index)::
3818
3819   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3820      actions queue / end
3821
3822As defined by *rte_flow*, the list is not ordered, all actions of a given
3823rule are performed simultaneously. These are equivalent::
3824
3825   queue index 6 / void / mark id 42 / end
3826
3827::
3828
3829   void / mark id 42 / queue index 6 / end
3830
3831All actions in a list should have different types, otherwise only the last
3832action of a given type is taken into account::
3833
3834   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3835
3836::
3837
3838   drop / drop / drop / end # drop is performed only once
3839
3840::
3841
3842   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3843
3844Considering they are performed simultaneously, opposite and overlapping
3845actions can sometimes be combined when the end result is unambiguous::
3846
3847   drop / queue index 6 / end # drop has no effect
3848
3849::
3850
3851   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3852
3853::
3854
3855   drop / passthru / end # drop has no effect
3856
3857Note that PMDs may still refuse such combinations.

4064Destroying flow rules
4065~~~~~~~~~~~~~~~~~~~~~
4066
4067``flow destroy`` destroys one or more rules from their rule ID (as returned
4068by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4069times as necessary::
4070
4071   flow destroy {port_id} rule {rule_id} [...]
4072
4073If successful, it will show::
4074
4075   Flow rule #[...] destroyed
4076
4077It does not report anything for rule IDs that do not exist. The usual error
4078message is shown when a rule cannot be destroyed::
4079
4080   Caught error type [...] ([...]): [...]
4081
4082``flow flush`` destroys all rules on a device and does not take extra
4083arguments. It is bound to ``rte_flow_flush()``::
4084
4085   flow flush {port_id}
4086
4087Any errors are reported as above.
4088
4089Creating several rules and destroying them::
4090
4091   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4092      actions queue index 2 / end
4093   Flow rule #0 created
4094   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4095      actions queue index 3 / end
4096   Flow rule #1 created
4097   testpmd> flow destroy 0 rule 0 rule 1
4098   Flow rule #1 destroyed
4099   Flow rule #0 destroyed
4100   testpmd>
4101
4102The same result can be achieved using ``flow flush``::
4103
4104   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4105      actions queue index 2 / end
4106   Flow rule #0 created
4107   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4108      actions queue index 3 / end
4109   Flow rule #1 created
4110   testpmd> flow flush 0
4111   testpmd>
4112
4113Non-existent rule IDs are ignored::
4114
4115   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4116      actions queue index 2 / end
4117   Flow rule #0 created
4118   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4119      actions queue index 3 / end
4120   Flow rule #1 created
4121   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4122   testpmd>
4123   testpmd> flow destroy 0 rule 0
4124   Flow rule #0 destroyed
4125   testpmd>
4126
4127Querying flow rules
4128~~~~~~~~~~~~~~~~~~~
4129
4130``flow query`` queries a specific action of a flow rule having that
4131ability. Such actions collect information that can be reported using this
4132command. It is bound to ``rte_flow_query()``::
4133
4134   flow query {port_id} {rule_id} {action}
4135
4136If successful, it will display either the retrieved data for known actions
4137or the following message::
4138
4139   Cannot display result for action type [...] ([...])
4140
4141Otherwise, it will complain either that the rule does not exist or that some
4142error occurred::
4143
4144   Flow rule #[...] not found
4145
4146::
4147
4148   Caught error type [...] ([...]): [...]
4149
4150Currently only the ``count`` action is supported. This action reports the
4151number of packets that hit the flow rule and the total number of bytes. Its
4152output has the following format::
4153
4154   count:
4155    hits_set: [...] # whether "hits" contains a valid value
4156    bytes_set: [...] # whether "bytes" contains a valid value
4157    hits: [...] # number of packets
4158    bytes: [...] # number of bytes
4159
4160Querying counters for TCPv6 packets redirected to queue 6::
4161
4162   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4163      actions queue index 6 / count / end
4164   Flow rule #4 created
4165   testpmd> flow query 0 4 count
4166   count:
4167    hits_set: 1
4168    bytes_set: 0
4169    hits: 386446
4170    bytes: 0
4171   testpmd>
4172
4173Listing flow rules
4174~~~~~~~~~~~~~~~~~~
4175
4176``flow list`` lists existing flow rules sorted by priority and optionally
4177filtered by group identifiers::
4178
4179   flow list {port_id} [group {group_id}] [...]
4180
4181This command only fails with the following message if the device does not
4182exist::
4183
4184   Invalid port [...]
4185
4186Output consists of a header line followed by a short description of each
4187flow rule, one per line. There is no output at all when no flow rules are
4188configured on the device::
4189
4190   ID      Group   Prio    Attr    Rule
4191   [...]   [...]   [...]   [...]   [...]
4192
4193``Attr`` column flags:
4194
4195- ``i`` for ``ingress``.
4196- ``e`` for ``egress``.
4197
4198Creating several flow rules and listing them::
4199
4200   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4201      actions queue index 6 / end
4202   Flow rule #0 created
4203   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4204      actions queue index 2 / end
4205   Flow rule #1 created
4206   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4207      actions rss queues 6 7 8 end / end
4208   Flow rule #2 created
4209   testpmd> flow list 0
4210   ID      Group   Prio    Attr    Rule
4211   0       0       0       i-      ETH IPV4 => QUEUE
4212   1       0       0       i-      ETH IPV6 => QUEUE
4213   2       0       5       i-      ETH IPV4 UDP => RSS
4214   testpmd>
4215
4216Rules are sorted by priority (i.e. group ID first, then priority level)::
4217
4218   testpmd> flow list 1
4219   ID      Group   Prio    Attr    Rule
4220   0       0       0       i-      ETH => COUNT
4221   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4222   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4223   1       24      0       i-      ETH IPV4 UDP => QUEUE
4224   4       24      10      i-      ETH IPV4 TCP => DROP
4225   3       24      20      i-      ETH IPV4 => DROP
4226   2       24      42      i-      ETH IPV4 UDP => QUEUE
4227   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4228   testpmd>
4229
4230Output can be limited to specific groups::
4231
4232   testpmd> flow list 1 group 0 group 63
4233   ID      Group   Prio    Attr    Rule
4234   0       0       0       i-      ETH => COUNT
4235   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4236   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4237   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4238   testpmd>
4239
4240Toggling isolated mode
4241~~~~~~~~~~~~~~~~~~~~~~
4242
4243``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4244must only be injected from the defined flow rules; that no default traffic
4245is expected outside those rules and the driver is free to assign more
4246resources to handle them. It is bound to ``rte_flow_isolate()``::
4247
4248 flow isolate {port_id} {boolean}
4249
4250If successful, enabling or disabling isolated mode shows either::
4251
4252 Ingress traffic on port [...]
4253    is now restricted to the defined flow rules
4254
4255Or::
4256
4257 Ingress traffic on port [...]
4258    is not restricted anymore to the defined flow rules
4259
4260Otherwise, in case of error::
4261
4262   Caught error type [...] ([...]): [...]
4263
4264Mainly due to its side effects, PMDs supporting this mode may not have the
4265ability to toggle it more than once without reinitializing affected ports
4266first (e.g. by exiting testpmd).
4267
4268Enabling isolated mode::
4269
4270 testpmd> flow isolate 0 true
4271 Ingress traffic on port 0 is now restricted to the defined flow rules
4272 testpmd>
4273
4274Disabling isolated mode::
4275
4276 testpmd> flow isolate 0 false
4277 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4278 testpmd>
4279
4280Dumping HW internal information
4281~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4282
4283``flow dump`` dumps the hardware's internal representation information of
4284all flows. It is bound to ``rte_flow_dev_dump()``::
4285
4286   flow dump {port_id} {output_file}
4287
4288If successful, it will show::
4289
4290   Flow dump finished
4291
4292Otherwise, it will complain error occurred::
4293
4294   Caught error type [...] ([...]): [...]
4295
4296Listing and destroying aged flow rules
4297~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4298
4299``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4300and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4301
4302   flow aged {port_id} [destroy]
4303
4304Listing current aged flow rules::
4305
4306   testpmd> flow aged 0
4307   Port 0 total aged flows: 0
4308   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4309      actions age timeout 5 / queue index 0 /  end
4310   Flow rule #0 created
4311   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4312      actions age timeout 4 / queue index 0 /  end
4313   Flow rule #1 created
4314   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4315      actions age timeout 2 / queue index 0 /  end
4316   Flow rule #2 created
4317   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4318      actions age timeout 3 / queue index 0 /  end
4319   Flow rule #3 created
4320
4321
4322Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4323information, all the aged flows are sorted by the longest timeout time. For example, if
4324those rules be configured in the same time, ID 2 will be the first aged out rule, the next

4353Creating shared actions
4354~~~~~~~~~~~~~~~~~~~~~~~
4355``flow shared_action {port_id} create`` creates shared action with optional
4356shared action ID. It is bound to ``rte_flow_shared_action_create()``::
4357
4358   flow shared_action {port_id} create [action_id {shared_action_id}]
4359      [ingress] [egress] [transfer] action {action} / end
4360
4361If successful, it will show::
4362
4363   Shared action #[...] created
4364
4365Otherwise, it will complain either that shared action already exists or that
4366some error occurred::
4367
4368   Shared action #[...] is already assigned, delete it first
4369
4370::
4371
4372   Caught error type [...] ([...]): [...]
4373
4374Create shared rss action with id 100 to queues 1 and 2 on port 0::
4375
4376   testpmd> flow shared_action 0 create action_id 100 \
4377      ingress action rss queues 1 2 end / end
4378
4379Create shared rss action with id assigned by testpmd to queues 1 and 2 on
4380port 0::
4381
4382	testpmd> flow shared_action 0 create action_id \
4383		ingress action rss queues 0 1 end / end
4384
4385Updating shared actions
4386~~~~~~~~~~~~~~~~~~~~~~~
4387``flow shared_action {port_id} update`` updates configuration of the shared
4388action from its shared action ID (as returned by
4389``flow shared_action {port_id} create``). It is bound to
4390``rte_flow_shared_action_update()``::
4391
4392   flow shared_action {port_id} update {shared_action_id}
4393      action {action} / end
4394
4395If successful, it will show::
4396
4397   Shared action #[...] updated
4398
4399Otherwise, it will complain either that shared action not found or that some
4400error occurred::
4401
4402   Failed to find shared action #[...] on port [...]
4403
4404::
4405
4406   Caught error type [...] ([...]): [...]
4407
4408Update shared rss action having id 100 on port 0 with rss to queues 0 and 3
4409(in create example above rss queues were 1 and 2)::
4410
4411   testpmd> flow shared_action 0 update 100 action rss queues 0 3 end / end
4412
4413Destroying shared actions
4414~~~~~~~~~~~~~~~~~~~~~~~~~
4415``flow shared_action {port_id} update`` destroys one or more shared actions
4416from their shared action IDs (as returned by
4417``flow shared_action {port_id} create``). It is bound to
4418``rte_flow_shared_action_destroy()``::
4419
4420   flow shared_action {port_id} destroy action_id {shared_action_id} [...]
4421
4422If successful, it will show::
4423
4424   Shared action #[...] destroyed
4425
4426It does not report anything for shared action IDs that do not exist.
4427The usual error message is shown when a shared action cannot be destroyed::
4428
4429   Caught error type [...] ([...]): [...]
4430
4431Destroy shared actions having id 100 & 101::
4432
4433   testpmd> flow shared_action 0 destroy action_id 100 action_id 101
4434
4435Query shared actions
4436~~~~~~~~~~~~~~~~~~~~
4437``flow shared_action {port_id} query`` queries the shared action from its
4438shared action ID (as returned by ``flow shared_action {port_id} create``).
4439It is bound to ``rte_flow_shared_action_query()``::
4440
4441  flow shared_action {port_id} query {shared_action_id}
4442
4443Currently only rss shared action supported. If successful, it will show::
4444
4445   Shared RSS action:
4446      refs:[...]
4447
4448Otherwise, it will complain either that shared action not found or that some
4449error occurred::
4450
4451   Failed to find shared action #[...] on port [...]
4452
4453::
4454
4455   Caught error type [...] ([...]): [...]
4456
4457Query shared action having id 100::
4458
4459   testpmd> flow shared_action 0 query 100
4460
4461Sample QinQ flow rules
4462~~~~~~~~~~~~~~~~~~~~~~
4463
4464Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4465
4466   testpmd> port stop 0
4467   testpmd> vlan set extend on 0
4468
4469The above command sets the inner and outer TPID's to 0x8100.
4470
4471To change the TPID's the following commands should be used::
4472
4473   testpmd> vlan set outer tpid 0x88A8 0
4474   testpmd> vlan set inner tpid 0x8100 0
4475   testpmd> port start 0
4476
4477Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4478
4479::
4480
4481   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4482       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4483   Flow rule #0 validated

4491   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
4492
4493Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4494
4495::
4496
4497   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4498        vlan tci is 654 / end actions pf / queue index 0 / end

4510Sample VXLAN flow rules
4511~~~~~~~~~~~~~~~~~~~~~~~
4512
4513Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4514filter on a port::
4515
4516  testpmd> rx_vxlan_port add 4789 0
4517
4518Create VXLAN rules on port 0 to steer traffic to PF queues.

4927BPF Functions
4928--------------
4929
4930The following sections show functions to load/unload eBPF based filters.
4931
4932bpf-load
4933~~~~~~~~
4934
4935Load an eBPF program as a callback for particular RX/TX queue::
4936
4937   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
4938
4939The available load-flags are:
4940
4941* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
4942
4943* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
4944
4945* ``-``: none.
4946
4947.. note::
4948
4949   You'll need clang v3.7 or above to build bpf program you'd like to load
4950
4951For example:
4952
4953.. code-block:: console
4954
4955   cd examples/bpf
4956   clang -O2 -target bpf -c t1.c
4957
4958Then to load (and JIT compile) t1.o at RX queue 0, port 1:
4959
4960.. code-block:: console
4961
4962   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
4963
4964To load (not JITed) t1.o at TX queue 0, port 0:
4965
4966.. code-block:: console
4967
4968   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
4969
4970bpf-unload
4971~~~~~~~~~~
4972
4973Unload previously loaded eBPF program for particular RX/TX queue::
4974
4975   testpmd> bpf-unload rx|tx (portid) (queueid)
4976
4977For example to unload BPF filter from TX queue 0, port 0:
4978
4979.. code-block:: console
4980
4981   testpmd> bpf-unload tx 0 0
4982
