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

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.

301   nb forwarding cores=2 - nb forwarding ports=1
302   RX queues=1 - RX desc=128 - RX free threshold=0
303   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
304   TX queues=1 - TX desc=512 - TX free threshold=0
305   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
306   TX RS bit threshold=0 - TXQ flags=0x0
307
308set fwd
309~~~~~~~
310
311Set the packet forwarding mode::
312
313   testpmd> set fwd (io|mac|macswap|flowgen| \
314                     rxonly|txonly|csum|icmpecho|noisy|5tswap) (""|retry)
315
316``retry`` can be specified for forwarding engines except ``rx_only``.
317
318The available information categories are:
319
320* ``io``: Forwards packets "as-is" in I/O mode.
321  This is the fastest possible forwarding operation as it does not access packets data.
322  This is the default mode.
323
324* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
325  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
326  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
327  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
328
329* ``macswap``: MAC swap forwarding mode.
330  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
331
332* ``flowgen``: Multi-flow generation mode.
333  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
334
335* ``rxonly``: Receives packets but doesn't transmit them.
336
337* ``txonly``: Generates and transmits packets without receiving any.
338
339* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
340
341* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
342
343* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
344
345* ``noisy``: Noisy neighbor simulation.
346  Simulate more realistic behavior of a guest machine engaged in receiving
347  and sending packets performing Virtual Network Function (VNF).
348
349* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
350
351  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
352
353  L3 swaps the source address and destination address of IP (v4 and v6).
354
355  L4 swaps the source port and destination port of transport layer (TCP and UDP).
356
357Example::
358
359   testpmd> set fwd rxonly
360
361   Set rxonly packet forwarding mode
362
363
364show fwd
365~~~~~~~~
366
367When running, forwarding engines maintain statistics from the time they have been started.

636Configuration Functions
637-----------------------
638
639The testpmd application can be configured from the runtime as well as from the command-line.
640
641This section details the available configuration functions that are available.
642
643.. note::
644
645   Configuration changes only become active when forwarding is started/restarted.
646
647set default
648~~~~~~~~~~~
649
650Reset forwarding to the default configuration::
651
652   testpmd> set default
653
654set verbose
655~~~~~~~~~~~
656
657Set the debug verbosity level::
658
659   testpmd> set verbose (level)
660
661Available levels are as following:
662
663* ``0`` silent except for error.
664* ``1`` fully verbose except for Tx packets.
665* ``2`` fully verbose except for Rx packets.
666* ``> 2`` fully verbose.
667
668set log
669~~~~~~~
670
671Set the log level for a log type::
672
673	testpmd> set log global|(type) (level)
674
675Where:
676
677* ``type`` is the log name.
678
679* ``level`` is the log level.
680
681For example, to change the global log level::
682
683	testpmd> set log global (level)
684
685Regexes can also be used for type. To change log level of user1, user2 and user3::
686
687	testpmd> set log user[1-3] (level)
688
689set nbport
690~~~~~~~~~~
691
692Set the number of ports used by the application:
693
694set nbport (num)
695
696This is equivalent to the ``--nb-ports`` command-line option.
697
698set nbcore
699~~~~~~~~~~
700
701Set the number of cores used by the application::
702
703   testpmd> set nbcore (num)
704
705This is equivalent to the ``--nb-cores`` command-line option.
706
707.. note::
708
709   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
710
711set coremask
712~~~~~~~~~~~~
713
714Set the forwarding cores hexadecimal mask::
715
716   testpmd> set coremask (mask)
717
718This is equivalent to the ``--coremask`` command-line option.
719
720.. note::
721
722   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
723
724set portmask
725~~~~~~~~~~~~
726
727Set the forwarding ports hexadecimal mask::
728
729   testpmd> set portmask (mask)
730
731This is equivalent to the ``--portmask`` command-line option.
732
733set record-core-cycles
734~~~~~~~~~~~~~~~~~~~~~~
735
736Set the recording of CPU cycles::
737
738   testpmd> set record-core-cycles (on|off)
739
740Where:
741
742* ``on`` enables measurement of CPU cycles per packet.
743
744* ``off`` disables measurement of CPU cycles per packet.
745
746This is equivalent to the ``--record-core-cycles command-line`` option.
747
748set record-burst-stats
749~~~~~~~~~~~~~~~~~~~~~~
750
751Set the displaying of RX and TX bursts::
752
753   testpmd> set record-burst-stats (on|off)
754
755Where:
756
757* ``on`` enables display of RX and TX bursts.
758
759* ``off`` disables display of RX and TX bursts.
760
761This is equivalent to the ``--record-burst-stats command-line`` option.
762
763set burst
764~~~~~~~~~
765
766Set number of packets per burst::
767
768   testpmd> set burst (num)
769
770This is equivalent to the ``--burst command-line`` option.
771
772When retry is enabled, the transmit delay time and number of retries can also be set::
773
774   testpmd> set burst tx delay (microseconds) retry (num)
775
776set rxoffs
777~~~~~~~~~~
778
779Set the offsets of segments relating to the data buffer beginning on receiving
780if split feature is engaged. Affects only the queues configured with split
781offloads (currently BUFFER_SPLIT is supported only).
782
783   testpmd> set rxoffs (x[,y]*)
784
785Where x[,y]* represents a CSV list of values, without white space. If the list
786of offsets is shorter than the list of segments the zero offsets will be used
787for the remaining segments.
788
789set rxpkts
790~~~~~~~~~~
791
792Set the length of segments to scatter packets on receiving if split
793feature is engaged. Affects only the queues configured with split offloads
794(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
795pools can be specified with --mbuf-size command line parameter and the mbufs
796to receive will be allocated sequentially from these extra memory pools (the
797mbuf for the first segment is allocated from the first pool, the second one
798from the second pool, and so on, if segment number is greater then pool's the
799mbuf for remaining segments will be allocated from the last valid pool).
800
801   testpmd> set rxpkts (x[,y]*)
802
803Where x[,y]* represents a CSV list of values, without white space. Zero value
804means to use the corresponding memory pool data buffer size.
805
806set txpkts
807~~~~~~~~~~
808
809Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
810
811   testpmd> set txpkts (x[,y]*)
812
813Where x[,y]* represents a CSV list of values, without white space.
814
815set txtimes
816~~~~~~~~~~~
817
818Configure the timing burst pattern for Tx only mode. This command enables
819the packet send scheduling on dynamic timestamp mbuf field and configures
820timing pattern in Tx only mode. In this mode, if scheduling is enabled
821application provides timestamps in the packets being sent. It is possible
822to configure delay (in unspecified device clock units) between bursts
823and between the packets within the burst::
824
825   testpmd> set txtimes (inter),(intra)
826
827where:
828
829* ``inter``  is the delay between the bursts in the device clock units.
830  If ``intra`` is zero, this is the time between the beginnings of the
831  first packets in the neighbour bursts, if ``intra`` is not zero,
832  ``inter`` specifies the time between the beginning of the first packet
833  of the current burst and the beginning of the last packet of the
834  previous burst. If ``inter`` parameter is zero the send scheduling
835  on timestamps is disabled (default).
836
837* ``intra`` is the delay between the packets within the burst specified
838  in the device clock units. The number of packets in the burst is defined
839  by regular burst setting. If ``intra`` parameter is zero no timestamps
840  provided in the packets excepting the first one in the burst.
841
842As the result the bursts of packet will be transmitted with specific
843delays between the packets within the burst and specific delay between
844the bursts. The rte_eth_read_clock() must be supported by the device(s)
845and is supposed to be engaged to get the current device clock value
846and provide the reference for the timestamps. If there is no supported
847rte_eth_read_clock() there will be no send scheduling provided on the port.
848
849set txsplit
850~~~~~~~~~~~
851
852Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
853
854   testpmd> set txsplit (off|on|rand)
855
856Where:
857
858* ``off`` disable packet copy & split for CSUM mode.
859
860* ``on`` split outgoing packet into multiple segments. Size of each segment
861  and number of segments per packet is determined by ``set txpkts`` command
862  (see above).
863
864* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
865
866set corelist
867~~~~~~~~~~~~
868
869Set the list of forwarding cores::
870
871   testpmd> set corelist (x[,y]*)
872
873For example, to change the forwarding cores:
874
875.. code-block:: console
876
877   testpmd> set corelist 3,1
878   testpmd> show config fwd
879
880   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
881   Logical Core 3 (socket 0) forwards packets on 1 streams:
882   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
883   Logical Core 1 (socket 0) forwards packets on 1 streams:
884   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
885
886.. note::

888   The cores are used in the same order as specified on the command line.
889
890set portlist
891~~~~~~~~~~~~
892
893Set the list of forwarding ports::
894
895   testpmd> set portlist (x[,y]*)

897For example, to change the port forwarding:
898
899.. code-block:: console
900
901   testpmd> set portlist 0,2,1,3
902   testpmd> show config fwd
903
904   io packet forwarding - ports=4 - cores=1 - streams=4
905   Logical Core 3 (socket 0) forwards packets on 4 streams:
906   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
907   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
908   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03

1132  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1133  supported). See also the ``csum parse-tunnel`` command.
1134
1135* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1136  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1137  supported). See also the ``csum parse-tunnel`` command.
1138
1139.. note::
1140
1141   Check the NIC Datasheet for hardware limits.
1142

1149		queue_start_index (value) queue_num (value)
1150
1151Set flowtype mapping on a RSS queue region on a port::
1152
1153   testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
1154

1166   testpmd> set port (port_id) queue-region flush (on|off)
1167
1168where:
1169
1170* ``on``: is just an enable function which server for other configuration,
1171  it is for all configuration about queue region from up layer,
1172  at first will only keep in DPDK software stored in driver,
1173  only after "flush on", it commit all configuration to HW.
1174
1175* ``"off``: is just clean all configuration about queue region just now,
1176  and restore all to DPDK i40e driver default config when start up.
1177
1178Show all queue region related configuration info on a port::
1179
1180   testpmd> show port (port_id) queue-region
1181
1182.. note::
1183
1184  Queue region only support on PF by now, so these command is
1185  only for configuration of queue region on PF port.
1186
1187csum parse-tunnel
1188~~~~~~~~~~~~~~~~~
1189
1190Define how tunneled packets should be handled by the csum forward
1191engine::
1192
1193   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1194
1195If enabled, the csum forward engine will try to recognize supported
1196tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1197
1198If disabled, treat tunnel packets as non-tunneled packets (a inner
1199header is handled as a packet payload).
1200
1201.. note::
1202
1203   The port argument is the TX port like in the ``csum set`` command.
1204
1205Example:
1206
1207Consider a packet in packet like the following::
1208
1209   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1210
1211* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1212  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1213  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1214
1215* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1216   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1257set port - gro
1258~~~~~~~~~~~~~~
1259
1260Enable or disable GRO in ``csum`` forwarding engine::
1261
1262   testpmd> set port <port_id> gro on|off
1263
1264If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1265packets received from the given port.
1266
1267If disabled, packets received from the given port won't be performed
1268GRO. By default, GRO is disabled for all ports.
1269
1270.. note::
1271
1272   When enable GRO for a port, TCP/IPv4 packets received from the port
1273   will be performed GRO. After GRO, all merged packets have bad
1274   checksums, since the GRO library doesn't re-calculate checksums for
1275   the merged packets. Therefore, if users want the merged packets to
1276   have correct checksums, please select HW IP checksum calculation and
1277   HW TCP checksum calculation for the port which the merged packets are
1278   transmitted to.
1279
1280show port - gro
1281~~~~~~~~~~~~~~~
1282
1283Display GRO configuration for a given port::
1284
1285   testpmd> show port <port_id> gro
1286
1287set gro flush
1288~~~~~~~~~~~~~
1289
1290Set the cycle to flush the GROed packets from reassembly tables::
1291
1292   testpmd> set gro flush <cycles>
1293
1294When enable GRO, the csum forwarding engine performs GRO on received
1295packets, and the GROed packets are stored in reassembly tables. Users
1296can use this command to determine when the GROed packets are flushed
1297from the reassembly tables.
1298
1299The ``cycles`` is measured in GRO operation times. The csum forwarding
1300engine flushes the GROed packets from the tables every ``cycles`` GRO
1301operations.
1302
1303By default, the value of ``cycles`` is 1, which means flush GROed packets
1304from the reassembly tables as soon as one GRO operation finishes. The value
1305of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1306
1307Please note that the large value of ``cycles`` may cause the poor TCP/IP
1308stack performance. Because the GROed packets are delayed to arrive the
1309stack, thus causing more duplicated ACKs and TCP retransmissions.
1310
1311set port - gso
1312~~~~~~~~~~~~~~
1313
1314Toggle per-port GSO support in ``csum`` forwarding engine::
1315
1316   testpmd> set port <port_id> gso on|off
1317
1318If enabled, the csum forwarding engine will perform GSO on supported IPv4
1319packets, transmitted on the given port.
1320
1321If disabled, packets transmitted on the given port will not undergo GSO.
1322By default, GSO is disabled for all ports.
1323
1324.. note::
1325
1326   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1327   port undergo GSO. Afterwards, the segmented packets are represented by
1328   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1329   of checksums for GSO'd segments in SW. As a result, if users want correct
1330   checksums in GSO segments, they should enable HW checksum calculation for
1331   GSO-enabled ports.
1332
1333   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1334   by setting the following options in the csum forwarding engine:
1335
1336   testpmd> csum set outer_ip hw <port_id>
1337
1338   testpmd> csum set ip hw <port_id>
1339
1340   testpmd> csum set tcp hw <port_id>
1341
1342   UDP GSO is the same as IP fragmentation, which treats the UDP header
1343   as the payload and does not modify it during segmentation. That is,
1344   after UDP GSO, only the first output fragment has the original UDP
1345   header. Therefore, users need to enable HW IP checksum calculation
1346   and SW UDP checksum calculation for GSO-enabled ports, if they want
1347   correct checksums for UDP/IPv4 packets.
1348
1349set gso segsz

2009Port Functions
2010--------------
2011
2012The following sections show functions for configuring ports.
2013
2014.. note::
2015
2016   Port configuration changes only become active when forwarding is started/restarted.
2017
2018port attach
2019~~~~~~~~~~~
2020
2021Attach a port specified by pci address or virtual device args::
2022
2023   testpmd> port attach (identifier)
2024
2025To attach a new pci device, the device should be recognized by kernel first.
2026Then it should be moved under DPDK management.
2027Finally the port can be attached to testpmd.
2028
2029For example, to move a pci device using ixgbe under DPDK management:
2030
2031.. code-block:: console
2032
2033   # Check the status of the available devices.
2034   ./usertools/dpdk-devbind.py --status
2035
2036   Network devices using DPDK-compatible driver
2037   ============================================
2038   <none>
2039
2040   Network devices using kernel driver
2041   ===================================
2042   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2043
2044
2045   # Bind the device to igb_uio.
2046   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2047
2048
2049   # Recheck the status of the devices.
2050   ./usertools/dpdk-devbind.py --status
2051   Network devices using DPDK-compatible driver
2052   ============================================
2053   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2054
2055To attach a port created by virtual device, above steps are not needed.
2056
2057For example, to attach a port whose pci address is 0000:0a:00.0.
2058
2059.. code-block:: console
2060
2061   testpmd> port attach 0000:0a:00.0
2062   Attaching a new port...
2063   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2064   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
2065   EAL:   PCI memory mapped at 0x7f83bfa00000
2066   EAL:   PCI memory mapped at 0x7f83bfa80000
2067   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2068   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2069   Port 0 is attached. Now total ports is 1
2070   Done
2071
2072For example, to attach a port created by pcap PMD.
2073
2074.. code-block:: console
2075
2076   testpmd> port attach net_pcap0
2077   Attaching a new port...
2078   PMD: Initializing pmd_pcap for net_pcap0
2079   PMD: Creating pcap-backed ethdev on numa socket 0
2080   Port 0 is attached. Now total ports is 1
2081   Done
2082
2083In this case, identifier is ``net_pcap0``.
2084This identifier format is the same as ``--vdev`` format of DPDK applications.
2085
2086For example, to re-attach a bonded port which has been previously detached,
2087the mode and slave parameters must be given.
2088
2089.. code-block:: console
2090
2091   testpmd> port attach net_bond_0,mode=0,slave=1
2092   Attaching a new port...
2093   EAL: Initializing pmd_bond for net_bond_0
2094   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2095   Port 0 is attached. Now total ports is 1
2096   Done
2097
2098
2099port detach
2100~~~~~~~~~~~
2101
2102Detach a specific port::
2103
2104   testpmd> port detach (port_id)
2105
2106Before detaching a port, the port should be stopped and closed.
2107
2108For example, to detach a pci device port 0.
2109
2110.. code-block:: console
2111
2112   testpmd> port stop 0
2113   Stopping ports...
2114   Done
2115   testpmd> port close 0
2116   Closing ports...
2117   Done
2118
2119   testpmd> port detach 0
2120   Detaching a port...
2121   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2122   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd

2124   EAL:   PCI memory unmapped at 0x7f83bfa80000
2125   Done
2126
2127
2128For example, to detach a virtual device port 0.
2129
2130.. code-block:: console
2131
2132   testpmd> port stop 0
2133   Stopping ports...
2134   Done
2135   testpmd> port close 0
2136   Closing ports...
2137   Done
2138
2139   testpmd> port detach 0
2140   Detaching a port...
2141   PMD: Closing pcap ethdev on numa socket 0
2142   Port 'net_pcap0' is detached. Now total ports is 0
2143   Done
2144
2145To remove a pci device completely from the system, first detach the port from testpmd.
2146Then the device should be moved under kernel management.
2147Finally the device can be removed using kernel pci hotplug functionality.
2148
2149For example, to move a pci device under kernel management:
2150
2151.. code-block:: console
2152
2153   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2154
2155   ./usertools/dpdk-devbind.py --status

2251   testpmd> port config all max-pkt-len (value)
2252
2253This is equivalent to the ``--max-pkt-len`` command-line option.
2254
2255port config - max-lro-pkt-size
2256~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2257
2258Set the maximum LRO aggregated packet size::
2259

2268
2269   testpmd> port config all drop-en (on|off)
2270
2271Packet dropping when no receive buffers available is off by default.
2272
2273The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2274
2275port config - RSS
2276~~~~~~~~~~~~~~~~~
2277
2278Set the RSS (Receive Side Scaling) mode on or off::

2281
2282RSS is on by default.
2283
2284The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp.
2285
2286The ``default`` option enables all supported RSS types reported by device info.
2287

2305
2306port config - Burst
2307~~~~~~~~~~~~~~~~~~~
2308
2309Set the number of packets per burst::
2310

2436Device Functions
2437----------------
2438
2439The following sections show functions for device operations.
2440
2441device detach
2442~~~~~~~~~~~~~
2443
2444Detach a device specified by pci address or virtual device args::
2445
2446   testpmd> device detach (identifier)
2447
2448Before detaching a device associated with ports, the ports should be stopped and closed.
2449
2450For example, to detach a pci device whose address is 0002:03:00.0.
2451
2452.. code-block:: console
2453
2454    testpmd> device detach 0002:03:00.0
2455    Removing a device...
2456    Port 1 is now closed
2457    EAL: Releasing pci mapped resource for 0002:03:00.0
2458    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2459    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2460    Device 0002:03:00.0 is detached
2461    Now total ports is 1
2462
2463For example, to detach a port created by pcap PMD.
2464
2465.. code-block:: console
2466
2467    testpmd> device detach net_pcap0
2468    Removing a device...
2469    Port 0 is now closed
2470    Device net_pcap0 is detached
2471    Now total ports is 0
2472    Done
2473
2474In this case, identifier is ``net_pcap0``.
2475This identifier format is the same as ``--vdev`` format of DPDK applications.
2476
2477Link Bonding Functions
2478----------------------
2479
2480The Link Bonding functions make it possible to dynamically create and
2481manage link bonding devices from within testpmd interactive prompt.

2498Adds Ethernet device to a Link Bonding device::
2499
2500   testpmd> add bonding slave (slave id) (port id)
2501
2502For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2503
2504   testpmd> add bonding slave 6 10
2505
2506
2507remove bonding slave
2508~~~~~~~~~~~~~~~~~~~~
2509
2510Removes an Ethernet slave device from a Link Bonding device::
2511
2512   testpmd> remove bonding slave (slave id) (port id)
2513
2514For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::
2515

2555
2556   testpmd> set bonding balance_xmit_policy (port_id) (l2|l23|l34)
2557
2558For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2559
2560   testpmd> set bonding balance_xmit_policy 10 l34
2561
2562
2563set bonding mon_period
2564~~~~~~~~~~~~~~~~~~~~~~

2567
2568This adds support for PMD slave devices which do not support link status interrupts.
2569When the mon_period is set to a value greater than 0 then all PMD's which do not support
2570link status ISR will be queried every polling interval to check if their link status has changed::
2571
2572   testpmd> set bonding mon_period (port_id) (value)
2573
2574For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

2600
2601   testpmd> show bonding config (port id)
2602
2603For example,
2604to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
2605in balance mode with a transmission policy of layer 2+3::
2606
2607   testpmd> show bonding config 9
2608        Bonding mode: 2
2609        Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23

3217Filter Functions
3218----------------
3219
3220This section details the available filter functions that are available.
3221
3222Note these functions interface the deprecated legacy filtering framework,
3223superseded by *rte_flow*. See `Flow rules management`_.
3224
3225.. _testpmd_flow_director:
3226
3227flow_director_filter
3228~~~~~~~~~~~~~~~~~~~~
3229
3230The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
3231
3232Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
3233Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
3234
3235* Perfect match filters.
3236  The hardware checks a match between the masked fields of the received packets and the programmed filters.
3237  The masked fields are for IP flow.
3238
3239* Signature filters.
3240  The hardware checks a match between a hash-based signature of the masked fields of the received packet.
3241
3242* Perfect-mac-vlan match filters.
3243  The hardware checks a match between the masked fields of the received packets and the programmed filters.
3244  The masked fields are for MAC VLAN flow.
3245
3246* Perfect-tunnel match filters.
3247  The hardware checks a match between the masked fields of the received packets and the programmed filters.
3248  The masked fields are for tunnel flow.
3249
3250* Perfect-raw-flow-type match filters.
3251  The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
3252  The masked fields are specified by input sets.
3253
3254The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
3255per flow type and the flexible payload.
3256
3257The Flow Director can also mask out parts of all of these fields so that filters
3258are only applied to certain fields or parts of the fields.
3259
3260Note that for raw flow type mode the source and destination fields in the
3261raw packet buffer need to be presented in a reversed order with respect
3262to the expected received packets.
3263For example: IP source and destination addresses or TCP/UDP/SCTP
3264source and destination ports
3265
3266Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

3456
3457The Flow Director filters can match the different fields for different type of packet, i.e. specific input set
3458on per flow type and the flexible payload. This command can be used to change input set for each flow type.
3459
3460Set the input set for flow director::

3486
3487Flow rules management
3488---------------------
3489
3490Control of the generic flow API (*rte_flow*) is fully exposed through the
3491``flow`` command (validation, creation, destruction, queries and operation
3492modes).
3493
3494Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3495features simultaneously may cause undefined side-effects and is therefore
3496not recommended.
3497
3498``flow`` syntax
3499~~~~~~~~~~~~~~~
3500
3501Because the ``flow`` command uses dynamic tokens to handle the large number
3502of possible flow rules combinations, its behavior differs slightly from
3503other commands, in particular:
3504
3505- Pressing *?* or the *<tab>* key displays contextual help for the current
3506  token, not that of the entire command.
3507
3508- Optional and repeated parameters are supported (provided they are listed
3509  in the contextual help).
3510
3511The first parameter stands for the operation mode. Possible operations and
3512their general syntax are described below. They are covered in detail in the
3513following sections.
3514
3515- Check whether a flow rule can be created::
3516
3517   flow validate {port_id}
3518       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3519       pattern {item} [/ {item} [...]] / end
3520       actions {action} [/ {action} [...]] / end
3521
3522- Create a flow rule::
3523
3524   flow create {port_id}
3525       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3526       pattern {item} [/ {item} [...]] / end
3527       actions {action} [/ {action} [...]] / end
3528
3529- Destroy specific flow rules::
3530
3531   flow destroy {port_id} rule {rule_id} [...]
3532
3533- Destroy all flow rules::
3534
3535   flow flush {port_id}
3536
3537- Query an existing flow rule::
3538
3539   flow query {port_id} {rule_id} {action}
3540
3541- List existing flow rules sorted by priority, filtered by group
3542  identifiers::
3543
3544   flow list {port_id} [group {group_id}] [...]
3545
3546- Restrict ingress traffic to the defined flow rules::
3547
3548   flow isolate {port_id} {boolean}
3549
3550- Dump internal representation information of all flows in hardware::
3551
3552   flow dump {port_id} {output_file}
3553
3554- List and destroy aged flow rules::
3555
3556   flow aged {port_id} [destroy]
3557
3558- Tunnel offload - create a tunnel stub::
3559
3560   flow tunnel create {port_id} type {tunnel_type}
3561
3562- Tunnel offload - destroy a tunnel stub::
3563
3564   flow tunnel destroy {port_id} id {tunnel_id}
3565
3566- Tunnel offload - list port tunnel stubs::
3567
3568   flow tunnel list {port_id}
3569
3570Creating a tunnel stub for offload
3571~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3572
3573``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3574
3575   flow tunnel create {port_id} type {tunnel_type}
3576
3577If successful, it will return a tunnel stub ID usable with other commands::
3578
3579   port [...]: flow tunnel #[...] type [...]
3580
3581Tunnel stub ID is relative to a port.
3582
3583Destroying tunnel offload stub
3584~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3585
3586``flow tunnel destroy`` destroy port tunnel stub::
3587
3588   flow tunnel destroy {port_id} id {tunnel_id}
3589
3590Listing tunnel offload stubs
3591~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3592
3593``flow tunnel list`` list port tunnel offload stubs::
3594
3595   flow tunnel list {port_id}
3596
3597Validating flow rules
3598~~~~~~~~~~~~~~~~~~~~~
3599
3600``flow validate`` reports whether a flow rule would be accepted by the
3601underlying device in its current state but stops short of creating it. It is
3602bound to ``rte_flow_validate()``::
3603
3604   flow validate {port_id}
3605      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3606      pattern {item} [/ {item} [...]] / end
3607      actions {action} [/ {action} [...]] / end
3608
3609If successful, it will show::
3610
3611   Flow rule validated
3612
3613Otherwise it will show an error message of the form::
3614
3615   Caught error type [...] ([...]): [...]
3616
3617This command uses the same parameters as ``flow create``, their format is
3618described in `Creating flow rules`_.
3619
3620Check whether redirecting any Ethernet packet received on port 0 to RX queue
3621index 6 is supported::
3622
3623   testpmd> flow validate 0 ingress pattern eth / end
3624      actions queue index 6 / end
3625   Flow rule validated
3626   testpmd>
3627
3628Port 0 does not support TCPv6 rules::
3629
3630   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3631      actions drop / end
3632   Caught error type 9 (specific pattern item): Invalid argument
3633   testpmd>
3634
3635Creating flow rules
3636~~~~~~~~~~~~~~~~~~~
3637
3638``flow create`` validates and creates the specified flow rule. It is bound
3639to ``rte_flow_create()``::
3640
3641   flow create {port_id}
3642      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3643      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3644      pattern {item} [/ {item} [...]] / end
3645      actions {action} [/ {action} [...]] / end
3646
3647If successful, it will return a flow rule ID usable with other commands::
3648
3649   Flow rule #[...] created
3650
3651Otherwise it will show an error message of the form::
3652
3653   Caught error type [...] ([...]): [...]
3654
3655Parameters describe in the following order:
3656
3657- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3658- Tunnel offload specification (tunnel_set, tunnel_match)
3659- A matching pattern, starting with the *pattern* token and terminated by an
3660  *end* pattern item.
3661- Actions, starting with the *actions* token and terminated by an *end*
3662  action.
3663
3664These translate directly to *rte_flow* objects provided as-is to the
3665underlying functions.
3666
3667The shortest valid definition only comprises mandatory tokens::
3668
3669   testpmd> flow create 0 pattern end actions end
3670
3671Note that PMDs may refuse rules that essentially do nothing such as this
3672one.
3673
3674**All unspecified object values are automatically initialized to 0.**
3675
3676Attributes
3677^^^^^^^^^^
3678
3679These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3680specified before the ``pattern`` token.
3681
3682- ``group {group id}``: priority group.
3683- ``priority {level}``: priority level within group.
3684- ``ingress``: rule applies to ingress traffic.
3685- ``egress``: rule applies to egress traffic.
3686- ``transfer``: apply rule directly to endpoints found in pattern.
3687
3688Each instance of an attribute specified several times overrides the previous
3689value as shown below (group 4 is used)::
3690
3691   testpmd> flow create 0 group 42 group 24 group 4 [...]
3692
3693Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3694
3695While not specifying a direction is an error, some rules may allow both
3696simultaneously.
3697
3698Most rules affect RX therefore contain the ``ingress`` token::
3699
3700   testpmd> flow create 0 ingress pattern [...]
3701
3702Tunnel offload
3703^^^^^^^^^^^^^^
3704
3705Indicate tunnel offload rule type
3706
3707- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3708- ``tunnel_match {tunnel_id}``:  mark rule as tunel offload match type.
3709
3710Matching pattern
3711^^^^^^^^^^^^^^^^
3712
3713A matching pattern starts after the ``pattern`` token. It is made of pattern
3714items and is terminated by a mandatory ``end`` item.
3715
3716Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3717rte_flow_item_type``).
3718
3719The ``/`` token is used as a separator between pattern items as shown
3720below::
3721
3722   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3723
3724Note that protocol items like these must be stacked from lowest to highest
3725layer to make sense. For instance, the following rule is either invalid or
3726unlikely to match any packet::
3727
3728   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3729
3730More information on these restrictions can be found in the *rte_flow*
3731documentation.
3732
3733Several items support additional specification structures, for example
3734``ipv4`` allows specifying source and destination addresses as follows::
3735
3736   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3737      dst is 10.2.0.0 / end [...]
3738
3739This rule matches all IPv4 traffic with the specified properties.
3740
3741In this example, ``src`` and ``dst`` are field names of the underlying
3742``struct rte_flow_item_ipv4`` object. All item properties can be specified
3743in a similar fashion.
3744
3745The ``is`` token means that the subsequent value must be matched exactly,
3746and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3747accordingly. Possible assignment tokens are:
3748
3749- ``is``: match value perfectly (with full bit-mask).
3750- ``spec``: match value according to configured bit-mask.
3751- ``last``: specify upper bound to establish a range.
3752- ``mask``: specify bit-mask with relevant bits set to one.
3753- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3754
3755These yield identical results::
3756
3757   ipv4 src is 10.1.1.1
3758
3759::
3760
3761   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3762
3763::
3764
3765   ipv4 src spec 10.1.1.1 src prefix 32
3766
3767::
3768
3769   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3770
3771::
3772
3773   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3774
3775Inclusive ranges can be defined with ``last``::
3776
3777   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3778
3779Note that ``mask`` affects both ``spec`` and ``last``::
3780
3781   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3782      # matches 10.1.0.0 to 10.2.255.255
3783
3784Properties can be modified multiple times::
3785
3786   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3787
3788::
3789
3790   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3995Actions list
3996^^^^^^^^^^^^
3997
3998A list of actions starts after the ``actions`` token in the same fashion as
3999`Matching pattern`_; actions are separated by ``/`` tokens and the list is
4000terminated by a mandatory ``end`` action.
4001
4002Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
4003rte_flow_action_type``).
4004
4005Dropping all incoming UDPv4 packets can be expressed as follows::
4006
4007   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
4008      actions drop / end
4009
4010Several actions have configurable properties which must be specified when
4011there is no valid default value. For example, ``queue`` requires a target
4012queue index.
4013
4014This rule redirects incoming UDPv4 traffic to queue index 6::
4015
4016   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
4017      actions queue index 6 / end
4018
4019While this one could be rejected by PMDs (unspecified queue index)::
4020
4021   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
4022      actions queue / end
4023
4024As defined by *rte_flow*, the list is not ordered, all actions of a given
4025rule are performed simultaneously. These are equivalent::
4026
4027   queue index 6 / void / mark id 42 / end
4028
4029::
4030
4031   void / mark id 42 / queue index 6 / end
4032
4033All actions in a list should have different types, otherwise only the last
4034action of a given type is taken into account::
4035
4036   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
4037
4038::
4039
4040   drop / drop / drop / end # drop is performed only once
4041
4042::
4043
4044   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
4045
4046Considering they are performed simultaneously, opposite and overlapping
4047actions can sometimes be combined when the end result is unambiguous::
4048
4049   drop / queue index 6 / end # drop has no effect
4050
4051::
4052
4053   queue index 6 / rss queues 6 7 8 / end # queue has no effect
4054
4055::
4056
4057   drop / passthru / end # drop has no effect
4058
4059Note that PMDs may still refuse such combinations.

4255
4256  - ``dscp_value {unsigned}``: The new DSCP value to be set
4257
4258- ``set_ipv6_dscp``: Set IPv6 DSCP value with specified value

4267Destroying flow rules
4268~~~~~~~~~~~~~~~~~~~~~
4269
4270``flow destroy`` destroys one or more rules from their rule ID (as returned
4271by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4272times as necessary::
4273
4274   flow destroy {port_id} rule {rule_id} [...]
4275
4276If successful, it will show::
4277
4278   Flow rule #[...] destroyed
4279
4280It does not report anything for rule IDs that do not exist. The usual error
4281message is shown when a rule cannot be destroyed::
4282
4283   Caught error type [...] ([...]): [...]
4284
4285``flow flush`` destroys all rules on a device and does not take extra
4286arguments. It is bound to ``rte_flow_flush()``::
4287
4288   flow flush {port_id}
4289
4290Any errors are reported as above.
4291
4292Creating several rules and destroying them::
4293
4294   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4295      actions queue index 2 / end
4296   Flow rule #0 created
4297   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4298      actions queue index 3 / end
4299   Flow rule #1 created
4300   testpmd> flow destroy 0 rule 0 rule 1
4301   Flow rule #1 destroyed
4302   Flow rule #0 destroyed
4303   testpmd>
4304
4305The same result can be achieved using ``flow flush``::
4306
4307   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4308      actions queue index 2 / end
4309   Flow rule #0 created
4310   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4311      actions queue index 3 / end
4312   Flow rule #1 created
4313   testpmd> flow flush 0
4314   testpmd>
4315
4316Non-existent rule IDs are ignored::
4317
4318   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4319      actions queue index 2 / end
4320   Flow rule #0 created
4321   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4322      actions queue index 3 / end
4323   Flow rule #1 created
4324   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4325   testpmd>
4326   testpmd> flow destroy 0 rule 0
4327   Flow rule #0 destroyed
4328   testpmd>
4329
4330Querying flow rules
4331~~~~~~~~~~~~~~~~~~~
4332
4333``flow query`` queries a specific action of a flow rule having that
4334ability. Such actions collect information that can be reported using this
4335command. It is bound to ``rte_flow_query()``::
4336
4337   flow query {port_id} {rule_id} {action}
4338
4339If successful, it will display either the retrieved data for known actions
4340or the following message::
4341
4342   Cannot display result for action type [...] ([...])
4343
4344Otherwise, it will complain either that the rule does not exist or that some
4345error occurred::
4346
4347   Flow rule #[...] not found
4348
4349::
4350
4351   Caught error type [...] ([...]): [...]
4352
4353Currently only the ``count`` action is supported. This action reports the
4354number of packets that hit the flow rule and the total number of bytes. Its
4355output has the following format::
4356
4357   count:
4358    hits_set: [...] # whether "hits" contains a valid value
4359    bytes_set: [...] # whether "bytes" contains a valid value
4360    hits: [...] # number of packets
4361    bytes: [...] # number of bytes
4362
4363Querying counters for TCPv6 packets redirected to queue 6::
4364
4365   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4366      actions queue index 6 / count / end
4367   Flow rule #4 created
4368   testpmd> flow query 0 4 count
4369   count:
4370    hits_set: 1
4371    bytes_set: 0
4372    hits: 386446
4373    bytes: 0
4374   testpmd>
4375
4376Listing flow rules
4377~~~~~~~~~~~~~~~~~~
4378
4379``flow list`` lists existing flow rules sorted by priority and optionally
4380filtered by group identifiers::
4381
4382   flow list {port_id} [group {group_id}] [...]
4383
4384This command only fails with the following message if the device does not
4385exist::
4386
4387   Invalid port [...]
4388
4389Output consists of a header line followed by a short description of each
4390flow rule, one per line. There is no output at all when no flow rules are
4391configured on the device::
4392
4393   ID      Group   Prio    Attr    Rule
4394   [...]   [...]   [...]   [...]   [...]
4395
4396``Attr`` column flags:
4397
4398- ``i`` for ``ingress``.
4399- ``e`` for ``egress``.
4400
4401Creating several flow rules and listing them::
4402
4403   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4404      actions queue index 6 / end
4405   Flow rule #0 created
4406   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4407      actions queue index 2 / end
4408   Flow rule #1 created
4409   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4410      actions rss queues 6 7 8 end / end
4411   Flow rule #2 created
4412   testpmd> flow list 0
4413   ID      Group   Prio    Attr    Rule
4414   0       0       0       i-      ETH IPV4 => QUEUE
4415   1       0       0       i-      ETH IPV6 => QUEUE
4416   2       0       5       i-      ETH IPV4 UDP => RSS
4417   testpmd>
4418
4419Rules are sorted by priority (i.e. group ID first, then priority level)::
4420
4421   testpmd> flow list 1
4422   ID      Group   Prio    Attr    Rule
4423   0       0       0       i-      ETH => COUNT
4424   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4425   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4426   1       24      0       i-      ETH IPV4 UDP => QUEUE
4427   4       24      10      i-      ETH IPV4 TCP => DROP
4428   3       24      20      i-      ETH IPV4 => DROP
4429   2       24      42      i-      ETH IPV4 UDP => QUEUE
4430   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4431   testpmd>
4432
4433Output can be limited to specific groups::
4434
4435   testpmd> flow list 1 group 0 group 63
4436   ID      Group   Prio    Attr    Rule
4437   0       0       0       i-      ETH => COUNT
4438   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4439   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4440   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4441   testpmd>
4442
4443Toggling isolated mode
4444~~~~~~~~~~~~~~~~~~~~~~
4445
4446``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4447must only be injected from the defined flow rules; that no default traffic
4448is expected outside those rules and the driver is free to assign more
4449resources to handle them. It is bound to ``rte_flow_isolate()``::
4450
4451 flow isolate {port_id} {boolean}
4452
4453If successful, enabling or disabling isolated mode shows either::
4454
4455 Ingress traffic on port [...]
4456    is now restricted to the defined flow rules
4457
4458Or::
4459
4460 Ingress traffic on port [...]
4461    is not restricted anymore to the defined flow rules
4462
4463Otherwise, in case of error::
4464
4465   Caught error type [...] ([...]): [...]
4466
4467Mainly due to its side effects, PMDs supporting this mode may not have the
4468ability to toggle it more than once without reinitializing affected ports
4469first (e.g. by exiting testpmd).
4470
4471Enabling isolated mode::
4472
4473 testpmd> flow isolate 0 true
4474 Ingress traffic on port 0 is now restricted to the defined flow rules
4475 testpmd>
4476
4477Disabling isolated mode::
4478
4479 testpmd> flow isolate 0 false
4480 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4481 testpmd>
4482
4483Dumping HW internal information
4484~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4485
4486``flow dump`` dumps the hardware's internal representation information of
4487all flows. It is bound to ``rte_flow_dev_dump()``::
4488
4489   flow dump {port_id} {output_file}
4490
4491If successful, it will show::
4492
4493   Flow dump finished
4494
4495Otherwise, it will complain error occurred::
4496
4497   Caught error type [...] ([...]): [...]
4498
4499Listing and destroying aged flow rules
4500~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4501
4502``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4503and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4504
4505   flow aged {port_id} [destroy]
4506
4507Listing current aged flow rules::
4508
4509   testpmd> flow aged 0
4510   Port 0 total aged flows: 0
4511   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4512      actions age timeout 5 / queue index 0 /  end
4513   Flow rule #0 created
4514   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4515      actions age timeout 4 / queue index 0 /  end
4516   Flow rule #1 created
4517   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4518      actions age timeout 2 / queue index 0 /  end
4519   Flow rule #2 created
4520   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4521      actions age timeout 3 / queue index 0 /  end
4522   Flow rule #3 created
4523
4524
4525Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4526information, all the aged flows are sorted by the longest timeout time. For example, if
4527those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4528will be ID 3, ID 1, ID 0::
4529
4530   testpmd> flow aged 0
4531   Port 0 total aged flows: 4
4532   ID      Group   Prio    Attr
4533   2       0       0       i--
4534   3       0       0       i--
4535   1       0       0       i--
4536   0       0       0       i--
4537
4538If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.
4539
4540   testpmd> flow aged 0 destroy
4541   Port 0 total aged flows: 4
4542   ID      Group   Prio    Attr
4543   2       0       0       i--
4544   3       0       0       i--
4545   1       0       0       i--
4546   0       0       0       i--
4547
4548   Flow rule #2 destroyed
4549   Flow rule #3 destroyed
4550   Flow rule #1 destroyed
4551   Flow rule #0 destroyed
4552   4 flows be destroyed
4553   testpmd> flow aged 0
4554   Port 0 total aged flows: 0
4555
4556Creating shared actions
4557~~~~~~~~~~~~~~~~~~~~~~~
4558``flow shared_action {port_id} create`` creates shared action with optional
4559shared action ID. It is bound to ``rte_flow_shared_action_create()``::
4560
4561   flow shared_action {port_id} create [action_id {shared_action_id}]
4562      [ingress] [egress] action {action} / end
4563
4564If successful, it will show::
4565
4566   Shared action #[...] created
4567
4568Otherwise, it will complain either that shared action already exists or that
4569some error occurred::
4570
4571   Shared action #[...] is already assigned, delete it first
4572
4573::
4574
4575   Caught error type [...] ([...]): [...]
4576
4577Create shared rss action with id 100 to queues 1 and 2 on port 0::
4578
4579   testpmd> flow shared_action 0 create action_id 100 \
4580      ingress action rss queues 1 2 end / end
4581
4582Create shared rss action with id assigned by testpmd to queues 1 and 2 on
4583port 0::
4584
4585	testpmd> flow shared_action 0 create action_id \
4586		ingress action rss queues 0 1 end / end
4587
4588Updating shared actions
4589~~~~~~~~~~~~~~~~~~~~~~~
4590``flow shared_action {port_id} update`` updates configuration of the shared
4591action from its shared action ID (as returned by
4592``flow shared_action {port_id} create``). It is bound to
4593``rte_flow_shared_action_update()``::
4594
4595   flow shared_action {port_id} update {shared_action_id}
4596      action {action} / end
4597
4598If successful, it will show::
4599
4600   Shared action #[...] updated
4601
4602Otherwise, it will complain either that shared action not found or that some
4603error occurred::
4604
4605   Failed to find shared action #[...] on port [...]
4606
4607::
4608
4609   Caught error type [...] ([...]): [...]
4610
4611Update shared rss action having id 100 on port 0 with rss to queues 0 and 3
4612(in create example above rss queues were 1 and 2)::
4613
4614   testpmd> flow shared_action 0 update 100 action rss queues 0 3 end / end
4615
4616Destroying shared actions
4617~~~~~~~~~~~~~~~~~~~~~~~~~
4618``flow shared_action {port_id} update`` destroys one or more shared actions
4619from their shared action IDs (as returned by
4620``flow shared_action {port_id} create``). It is bound to
4621``rte_flow_shared_action_destroy()``::
4622
4623   flow shared_action {port_id} destroy action_id {shared_action_id} [...]
4624
4625If successful, it will show::
4626
4627   Shared action #[...] destroyed
4628
4629It does not report anything for shared action IDs that do not exist.
4630The usual error message is shown when a shared action cannot be destroyed::
4631
4632   Caught error type [...] ([...]): [...]
4633
4634Destroy shared actions having id 100 & 101::
4635
4636   testpmd> flow shared_action 0 destroy action_id 100 action_id 101
4637
4638Query shared actions
4639~~~~~~~~~~~~~~~~~~~~
4640``flow shared_action {port_id} query`` queries the shared action from its
4641shared action ID (as returned by ``flow shared_action {port_id} create``).
4642It is bound to ``rte_flow_shared_action_query()``::
4643
4644  flow shared_action {port_id} query {shared_action_id}
4645
4646Currently only rss shared action supported. If successful, it will show::
4647
4648   Shared RSS action:
4649      refs:[...]
4650
4651Otherwise, it will complain either that shared action not found or that some
4652error occurred::
4653
4654   Failed to find shared action #[...] on port [...]
4655
4656::
4657
4658   Caught error type [...] ([...]): [...]
4659
4660Query shared action having id 100::
4661
4662   testpmd> flow shared_action 0 query 100
4663
4664Sample QinQ flow rules
4665~~~~~~~~~~~~~~~~~~~~~~
4666
4667Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4668
4669   testpmd> port stop 0
4670   testpmd> vlan set qinq_strip on 0
4671
4672The above command sets the inner and outer TPID's to 0x8100.
4673
4674To change the TPID's the following commands should be used::
4675
4676   testpmd> vlan set outer tpid 0xa100 0
4677   testpmd> vlan set inner tpid 0x9100 0
4678   testpmd> port start 0
4679
4680Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4681
4682::
4683
4684   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4685       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4686   Flow rule #0 validated

4695
4696Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4697
4698::
4699
4700   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4701        vlan tci is 654 / end actions pf / queue index 0 / end

4712
4713Sample VXLAN flow rules
4714~~~~~~~~~~~~~~~~~~~~~~~
4715
4716Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4717filter on a port::
4718
4719  testpmd> rx_vxlan_port add 4789 0
4720
4721Create VXLAN rules on port 0 to steer traffic to PF queues.
4722
4723::
4724
4725  testpmd> flow create 0 ingress pattern eth / ipv4 / udp / vxlan /
4726         eth dst is 00:11:22:33:44:55 / end actions pf / queue index 1 / end
4727  Flow rule #0 created
4728
4729  testpmd> flow create 0 ingress pattern eth / ipv4 / udp / vxlan vni is 3 /
4730         eth dst is 00:11:22:33:44:55 / end actions pf / queue index 2 / end
4731  Flow rule #1 created
4732

5072BPF Functions
5073--------------
5074
5075The following sections show functions to load/unload eBPF based filters.
5076
5077bpf-load
5078~~~~~~~~
5079
5080Load an eBPF program as a callback for particular RX/TX queue::
5081
5082   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5083
5084The available load-flags are:
5085
5086* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5087
5088* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5089
5090* ``-``: none.
5091
5092.. note::
5093
5094   You'll need clang v3.7 or above to build bpf program you'd like to load
5095
5096For example:
5097
5098.. code-block:: console
5099
5100   cd examples/bpf
5101   clang -O2 -target bpf -c t1.c
5102
5103Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5104
5105.. code-block:: console
5106
5107   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5108
5109To load (not JITed) t1.o at TX queue 0, port 0:
5110
5111.. code-block:: console
5112
5113   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5114
5115bpf-unload
5116~~~~~~~~~~
5117
5118Unload previously loaded eBPF program for particular RX/TX queue::
5119
5120   testpmd> bpf-unload rx|tx (portid) (queueid)
5121
5122For example to unload BPF filter from TX queue 0, port 0:
5123
5124.. code-block:: console
5125
5126   testpmd> bpf-unload tx 0 0
5127
