6Testpmd Runtime Functions
7=========================
8
9Where the testpmd application is started in interactive mode, (``-i|--interactive``),
10it displays a prompt that can be used to start and stop forwarding,
11configure the application, display statistics (including the extended NIC
12statistics aka xstats) , set the Flow Director and other tasks::
13
14   testpmd>
15
16The testpmd prompt has some, limited, readline support.
17Common bash command-line functions such as ``Ctrl+a`` and ``Ctrl+e`` to go to the start and end of the prompt line are supported
18as well as access to the command history via the up-arrow.
19
20There is also support for tab completion.
21If you type a partial command and hit ``<TAB>`` you get a list of the available completions:
22
23.. code-block:: console
24
25   testpmd> show port <TAB>
26
27       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
28       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
29       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
30       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
31       ...
32
33
34.. note::
35
36   Some examples in this document are too long to fit on one line are shown wrapped at `"\\"` for display purposes::
37
38      testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
39               (pause_time) (send_xon) (port_id)
40
41In the real ``testpmd>`` prompt these commands should be on a single line.
42
43Help Functions
44--------------
45
46The testpmd has on-line help for the functions that are available at runtime.
47These are divided into sections and can be accessed using help, help section or help all:
48
49.. code-block:: console
50
51   testpmd> help
52       Help is available for the following sections:
53
54           help control                    : Start and stop forwarding.
55           help display                    : Displaying port, stats and config information.

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

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

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

308   nb forwarding cores=2 - nb forwarding ports=1
309   RX queues=1 - RX desc=128 - RX free threshold=0
310   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
311   TX queues=1 - TX desc=512 - TX free threshold=0
312   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
313   TX RS bit threshold=0 - TXQ flags=0x0
314
315set fwd
316~~~~~~~
317
318Set the packet forwarding mode::
319
320   testpmd> set fwd (io|mac|macswap|flowgen| \
321                     rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq|recycle_mbufs) (""|retry)
322
323``retry`` can be specified for forwarding engines except ``rx_only``.
324
325The available information categories are:
326
327* ``io``: Forwards packets "as-is" in I/O mode.
328  This is the fastest possible forwarding operation as it does not access packets data.
329  This is the default mode.
330
331* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
332  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
333  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
334  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
335
336* ``macswap``: MAC swap forwarding mode.
337  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
338
339* ``flowgen``: Multi-flow generation mode.
340  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
341
342* ``rxonly``: Receives packets but doesn't transmit them.
343
344* ``txonly``: Generates and transmits packets without receiving any.
345
346* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
347
348* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
349
350* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
351
352* ``noisy``: Noisy neighbor simulation.
353  Simulate more realistic behavior of a guest machine engaged in receiving
354  and sending packets performing Virtual Network Function (VNF).
355
356* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
357
358  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
359
360  L3 swaps the source address and destination address of IP (v4 and v6).
361
362  L4 swaps the source port and destination port of transport layer (TCP and UDP).
363
364* ``shared-rxq``: Receive only for shared Rx queue.
365  Resolve packet source port from mbuf and update stream statistics accordingly.
366
367* ``recycle_mbufs``:  Recycle Tx queue used mbufs for Rx queue mbuf ring.
368  This mode uses fast path mbuf recycle feature and forwards packets in I/O mode.
369
370Example::
371
372   testpmd> set fwd rxonly
373
374   Set rxonly packet forwarding mode
375
376
377show fwd
378~~~~~~~~
379
380When running, forwarding engines maintain statistics from the time they have been started.
381Example for the io forwarding engine, with some packet drops on the tx side::
382
383   testpmd> show fwd stats all
384

651Configuration Functions
652-----------------------
653
654The testpmd application can be configured from the runtime as well as from the command-line.
655
656This section details the available configuration functions that are available.
657
658.. note::
659
660   Configuration changes only become active when forwarding is started/restarted.
661
662set default
663~~~~~~~~~~~
664
665Reset forwarding to the default configuration::
666
667   testpmd> set default
668
669set verbose
670~~~~~~~~~~~
671
672Set the debug verbosity level::
673
674   testpmd> set verbose (level)
675
676Available levels are as following:
677
678* ``0`` silent except for error.
679* ``1`` fully verbose except for Tx packets.
680* ``2`` fully verbose except for Rx packets.
681* ``> 2`` fully verbose.
682
683set log
684~~~~~~~
685
686Set the log level for a log type::
687
688	testpmd> set log global|(type) (level)
689
690Where:
691
692* ``type`` is the log name.
693
694* ``level`` is the log level.
695
696For example, to change the global log level::
697
698	testpmd> set log global (level)
699
700Regexes can also be used for type. To change log level of user1, user2 and user3::
701
702	testpmd> set log user[1-3] (level)
703
704set nbport
705~~~~~~~~~~
706
707Set the number of ports used by the application:
708
709set nbport (num)
710
711This is equivalent to the ``--nb-ports`` command-line option.
712
713set nbcore
714~~~~~~~~~~
715
716Set the number of cores used by the application::
717
718   testpmd> set nbcore (num)
719
720This is equivalent to the ``--nb-cores`` command-line option.
721
722.. note::
723
724   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
725
726set coremask
727~~~~~~~~~~~~
728
729Set the forwarding cores hexadecimal mask::
730
731   testpmd> set coremask (mask)
732
733This is equivalent to the ``--coremask`` command-line option.
734
735.. note::
736
737   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
738
739set portmask
740~~~~~~~~~~~~
741
742Set the forwarding ports hexadecimal mask::
743
744   testpmd> set portmask (mask)
745
746This is equivalent to the ``--portmask`` command-line option.
747
748set record-core-cycles
749~~~~~~~~~~~~~~~~~~~~~~
750
751Set the recording of CPU cycles::
752
753   testpmd> set record-core-cycles (on|off)
754
755Where:
756
757* ``on`` enables measurement of CPU cycles per packet.
758
759* ``off`` disables measurement of CPU cycles per packet.
760
761This is equivalent to the ``--record-core-cycles command-line`` option.
762
763set record-burst-stats
764~~~~~~~~~~~~~~~~~~~~~~
765
766Set the displaying of RX and TX bursts::
767
768   testpmd> set record-burst-stats (on|off)
769
770Where:
771
772* ``on`` enables display of RX and TX bursts.
773
774* ``off`` disables display of RX and TX bursts.
775
776This is equivalent to the ``--record-burst-stats command-line`` option.
777
778set burst
779~~~~~~~~~
780
781Set number of packets per burst::
782
783   testpmd> set burst (num)
784
785This is equivalent to the ``--burst command-line`` option.
786
787When retry is enabled, the transmit delay time and number of retries can also be set::
788
789   testpmd> set burst tx delay (microseconds) retry (num)
790
791set rxoffs
792~~~~~~~~~~
793
794Set the offsets of segments relating to the data buffer beginning on receiving
795if split feature is engaged. Affects only the queues configured with split
796offloads (currently BUFFER_SPLIT is supported only).
797
798   testpmd> set rxoffs (x[,y]*)
799
800Where x[,y]* represents a CSV list of values, without white space. If the list
801of offsets is shorter than the list of segments the zero offsets will be used
802for the remaining segments.
803
804set rxpkts
805~~~~~~~~~~
806
807Set the length of segments to scatter packets on receiving if split
808feature is engaged. Affects only the queues configured with split offloads
809(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
810pools can be specified with --mbuf-size command line parameter and the mbufs
811to receive will be allocated sequentially from these extra memory pools (the
812mbuf for the first segment is allocated from the first pool, the second one
813from the second pool, and so on, if segment number is greater then pool's the
814mbuf for remaining segments will be allocated from the last valid pool).
815
816   testpmd> set rxpkts (x[,y]*)
817
818Where x[,y]* represents a CSV list of values, without white space. Zero value
819means to use the corresponding memory pool data buffer size.
820
821set rxhdrs
822~~~~~~~~~~
823
824Set the protocol headers of segments to scatter packets on receiving
825if split feature is engaged.
826Affects only the queues configured with split offloads
827(currently BUFFER_SPLIT is supported only).
828
829   testpmd> set rxhdrs (eth[,ipv4]*)
830
831Where eth[,ipv4]* represents a CSV list of values, without white space.
832If the list of offsets is shorter than the list of segments,
833zero offsets will be used for the remaining segments.
834
835set txpkts
836~~~~~~~~~~
837
838Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
839
840   testpmd> set txpkts (x[,y]*)
841
842Where x[,y]* represents a CSV list of values, without white space.
843
844set txtimes
845~~~~~~~~~~~
846
847Configure the timing burst pattern for Tx only mode. This command enables
848the packet send scheduling on dynamic timestamp mbuf field and configures
849timing pattern in Tx only mode. In this mode, if scheduling is enabled
850application provides timestamps in the packets being sent. It is possible
851to configure delay (in unspecified device clock units) between bursts
852and between the packets within the burst::
853
854   testpmd> set txtimes (inter),(intra)
855
856where:
857
858* ``inter``  is the delay between the bursts in the device clock units.
859  If ``intra`` is zero, this is the time between the beginnings of the
860  first packets in the neighbour bursts, if ``intra`` is not zero,
861  ``inter`` specifies the time between the beginning of the first packet
862  of the current burst and the beginning of the last packet of the
863  previous burst. If ``inter`` parameter is zero the send scheduling
864  on timestamps is disabled (default).
865
866* ``intra`` is the delay between the packets within the burst specified
867  in the device clock units. The number of packets in the burst is defined
868  by regular burst setting. If ``intra`` parameter is zero no timestamps
869  provided in the packets excepting the first one in the burst.
870
871As the result the bursts of packet will be transmitted with specific
872delays between the packets within the burst and specific delay between
873the bursts. The rte_eth_read_clock() must be supported by the device(s)
874and is supposed to be engaged to get the current device clock value
875and provide the reference for the timestamps. If there is no supported
876rte_eth_read_clock() there will be no send scheduling provided on the port.
877
878set txsplit
879~~~~~~~~~~~
880
881Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
882
883   testpmd> set txsplit (off|on|rand)
884
885Where:
886
887* ``off`` disable packet copy & split for CSUM mode.
888
889* ``on`` split outgoing packet into multiple segments. Size of each segment
890  and number of segments per packet is determined by ``set txpkts`` command
891  (see above).
892
893* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
894
895set corelist
896~~~~~~~~~~~~
897
898Set the list of forwarding cores::
899
900   testpmd> set corelist (x[,y]*)
901
902For example, to change the forwarding cores:
903
904.. code-block:: console
905
906   testpmd> set corelist 3,1
907   testpmd> show config fwd
908
909   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
910   Logical Core 3 (socket 0) forwards packets on 1 streams:
911   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
912   Logical Core 1 (socket 0) forwards packets on 1 streams:
913   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
914
915.. note::

929
930   testpmd> set portlist 0,2,1,3
931   testpmd> show config fwd
932
933   io packet forwarding - ports=4 - cores=1 - streams=4
934   Logical Core 3 (socket 0) forwards packets on 4 streams:
935   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
936   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
937   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
938   RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02

1090
1091Disable hardware insertion of a VLAN header in packets sent on a port::
1092
1093   testpmd> tx_vlan reset (port_id)
1094
1095csum set
1096~~~~~~~~
1097
1098Select hardware or software calculation of the checksum when
1099transmitting a packet using the ``csum`` forwarding engine::
1100
1101   testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
1102
1103Where:
1104
1105* ``ip|udp|tcp|sctp`` always relate to  the inner layer.
1106
1107* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
1108  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1109  supported). See also the ``csum parse-tunnel`` command.
1110
1111* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1112  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1113  supported). See also the ``csum parse-tunnel`` command.
1114
1115.. note::
1116
1117   Check the NIC Datasheet for hardware limits.
1118
1119csum parse-tunnel
1120~~~~~~~~~~~~~~~~~
1121
1122Define how tunneled packets should be handled by the csum forward
1123engine::
1124
1125   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1126
1127If enabled, the csum forward engine will try to recognize supported
1128tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1129
1130If disabled, treat tunnel packets as non-tunneled packets (a inner
1131header is handled as a packet payload).
1132
1133.. note::
1134
1135   The port argument is the TX port like in the ``csum set`` command.
1136
1137Example:
1138
1139Consider a packet in packet like the following::
1140
1141   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1142
1143* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1144  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1145  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1146
1147* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1148   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1186
1187   testpmd> tunnel_tso show (port_id)
1188
1189set port - gro
1190~~~~~~~~~~~~~~
1191
1192Enable or disable GRO in ``csum`` forwarding engine::
1193
1194   testpmd> set port <port_id> gro on|off
1195
1196If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1197packets received from the given port.
1198
1199If disabled, packets received from the given port won't be performed
1200GRO. By default, GRO is disabled for all ports.
1201
1202.. note::
1203
1204   When enable GRO for a port, TCP/IPv4 packets received from the port
1205   will be performed GRO. After GRO, all merged packets have bad
1206   checksums, since the GRO library doesn't re-calculate checksums for
1207   the merged packets. Therefore, if users want the merged packets to
1208   have correct checksums, please select HW IP checksum calculation and
1209   HW TCP checksum calculation for the port which the merged packets are
1210   transmitted to.
1211
1212show port - gro
1213~~~~~~~~~~~~~~~
1214
1215Display GRO configuration for a given port::
1216
1217   testpmd> show port <port_id> gro
1218
1219set gro flush
1220~~~~~~~~~~~~~
1221
1222Set the cycle to flush the GROed packets from reassembly tables::
1223
1224   testpmd> set gro flush <cycles>
1225
1226When enable GRO, the csum forwarding engine performs GRO on received
1227packets, and the GROed packets are stored in reassembly tables. Users
1228can use this command to determine when the GROed packets are flushed
1229from the reassembly tables.
1230
1231The ``cycles`` is measured in GRO operation times. The csum forwarding
1232engine flushes the GROed packets from the tables every ``cycles`` GRO
1233operations.
1234
1235By default, the value of ``cycles`` is 1, which means flush GROed packets
1236from the reassembly tables as soon as one GRO operation finishes. The value
1237of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1238
1239Please note that the large value of ``cycles`` may cause the poor TCP/IP
1240stack performance. Because the GROed packets are delayed to arrive the
1241stack, thus causing more duplicated ACKs and TCP retransmissions.
1242
1243set port - gso
1244~~~~~~~~~~~~~~
1245
1246Toggle per-port GSO support in ``csum`` forwarding engine::
1247
1248   testpmd> set port <port_id> gso on|off
1249
1250If enabled, the csum forwarding engine will perform GSO on supported IPv4
1251packets, transmitted on the given port.
1252
1253If disabled, packets transmitted on the given port will not undergo GSO.
1254By default, GSO is disabled for all ports.
1255
1256.. note::
1257
1258   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1259   port undergo GSO. Afterwards, the segmented packets are represented by
1260   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1261   of checksums for GSO'd segments in SW. As a result, if users want correct
1262   checksums in GSO segments, they should enable HW checksum calculation for
1263   GSO-enabled ports.
1264
1265   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1266   by setting the following options in the csum forwarding engine:
1267
1268   testpmd> csum set outer_ip hw <port_id>
1269
1270   testpmd> csum set ip hw <port_id>
1271
1272   testpmd> csum set tcp hw <port_id>
1273
1274   UDP GSO is the same as IP fragmentation, which treats the UDP header
1275   as the payload and does not modify it during segmentation. That is,
1276   after UDP GSO, only the first output fragment has the original UDP
1277   header. Therefore, users need to enable HW IP checksum calculation
1278   and SW UDP checksum calculation for GSO-enabled ports, if they want
1279   correct checksums for UDP/IPv4 packets.
1280
1281set gso segsz
1282~~~~~~~~~~~~~
1283
1284Set the maximum GSO segment size (measured in bytes), which includes the

1661 ip-dst (ip-dst) eth-src (eth-src) eth-dst (eth-dst)
1662
1663These commands will set an internal configuration inside testpmd, any following
1664flow rule using the action vxlan_encap will use the last configuration set.
1665To have a different encapsulation header, one of those commands must be called
1666before the flow rule creation.

1690        eth-src (eth-src) eth-dst (eth-dst)
1691
1692Those commands will set an internal configuration inside testpmd, any following

1769Config Raw Encapsulation
1770~~~~~~~~~~~~~~~~~~~~~~~~~
1771
1772Configure the raw data to be used when encapsulating a packet by
1773rte_flow_action_raw_encap::
1774
1775 set raw_encap {index} {item} [/ {item} [...]] / end_set
1776
1777There are multiple global buffers for ``raw_encap``, this command will set one
1778internal buffer index by ``{index}``.
1779If there is no ``{index}`` specified::
1780
1781 set raw_encap {item} [/ {item} [...]] / end_set
1782
1783the default index ``0`` is used.
1784In order to use different encapsulating header, ``index`` must be specified
1785during the flow rule creation::
1786
1787 testpmd> flow create 0 egress pattern eth / ipv4 / end actions
1788        raw_encap index 2 / end
1789

1841Port Functions
1842--------------
1843
1844The following sections show functions for configuring ports.
1845
1846.. note::
1847
1848   Port configuration changes only become active when forwarding is started/restarted.
1849
1850.. _port_attach:
1851
1852port attach
1853~~~~~~~~~~~
1854
1855Attach a port specified by pci address or virtual device args::
1856
1857   testpmd> port attach (identifier)
1858
1859To attach a new pci device, the device should be recognized by kernel first.
1860Then it should be moved under DPDK management.
1861Finally the port can be attached to testpmd.
1862
1863For example, to move a pci device using ixgbe under DPDK management:
1864
1865.. code-block:: console
1866
1867   # Check the status of the available devices.
1868   ./usertools/dpdk-devbind.py --status
1869
1870   Network devices using DPDK-compatible driver
1871   ============================================
1872   <none>
1873
1874   Network devices using kernel driver
1875   ===================================
1876   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1877
1878
1879   # Bind the device to igb_uio.
1880   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1881
1882
1883   # Recheck the status of the devices.
1884   ./usertools/dpdk-devbind.py --status
1885   Network devices using DPDK-compatible driver
1886   ============================================
1887   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1888
1889To attach a port created by virtual device, above steps are not needed.
1890
1891For example, to attach a port whose pci address is 0000:0a:00.0.
1892
1893.. code-block:: console
1894
1895   testpmd> port attach 0000:0a:00.0
1896   Attaching a new port...
1897   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1898   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
1899   EAL:   PCI memory mapped at 0x7f83bfa00000
1900   EAL:   PCI memory mapped at 0x7f83bfa80000
1901   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1902   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1903   Port 0 is attached. Now total ports is 1
1904   Done
1905
1906For example, to attach a port created by pcap PMD.
1907
1908.. code-block:: console
1909
1910   testpmd> port attach net_pcap0
1911   Attaching a new port...
1912   PMD: Initializing pmd_pcap for net_pcap0
1913   PMD: Creating pcap-backed ethdev on numa socket 0
1914   Port 0 is attached. Now total ports is 1
1915   Done
1916
1917In this case, identifier is ``net_pcap0``.
1918This identifier format is the same as ``--vdev`` format of DPDK applications.
1919
1920For example, to re-attach a bonding port which has been previously detached,
1921the mode and slave parameters must be given.
1922
1923.. code-block:: console
1924
1925   testpmd> port attach net_bond_0,mode=0,slave=1
1926   Attaching a new port...
1927   EAL: Initializing pmd_bond for net_bond_0
1928   EAL: Create bonding device net_bond_0 on port 0 in mode 0 on socket 0.
1929   Port 0 is attached. Now total ports is 1
1930   Done
1931
1932
1933port detach
1934~~~~~~~~~~~
1935
1936Detach a specific port::
1937
1938   testpmd> port detach (port_id)
1939
1940Before detaching a port, the port should be stopped and closed.
1941
1942For example, to detach a pci device port 0.
1943
1944.. code-block:: console
1945
1946   testpmd> port stop 0
1947   Stopping ports...
1948   Done
1949   testpmd> port close 0
1950   Closing ports...
1951   Done
1952
1953   testpmd> port detach 0
1954   Detaching a port...
1955   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1956   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
1957   EAL:   PCI memory unmapped at 0x7f83bfa00000
1958   EAL:   PCI memory unmapped at 0x7f83bfa80000
1959   Done
1960
1961
1962For example, to detach a virtual device port 0.
1963
1964.. code-block:: console
1965
1966   testpmd> port stop 0
1967   Stopping ports...
1968   Done
1969   testpmd> port close 0
1970   Closing ports...
1971   Done
1972
1973   testpmd> port detach 0
1974   Detaching a port...
1975   PMD: Closing pcap ethdev on numa socket 0
1976   Port 'net_pcap0' is detached. Now total ports is 0
1977   Done
1978
1979To remove a pci device completely from the system, first detach the port from testpmd.
1980Then the device should be moved under kernel management.
1981Finally the device can be removed using kernel pci hotplug functionality.
1982
1983For example, to move a pci device under kernel management:
1984
1985.. code-block:: console
1986
1987   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1988
1989   ./usertools/dpdk-devbind.py --status

2280device detach
2281~~~~~~~~~~~~~
2282
2283Detach a device specified by pci address or virtual device args::
2284
2285   testpmd> device detach (identifier)
2286
2287Before detaching a device associated with ports, the ports should be stopped and closed.
2288
2289For example, to detach a pci device whose address is 0002:03:00.0.
2290
2291.. code-block:: console
2292
2293    testpmd> device detach 0002:03:00.0
2294    Removing a device...
2295    Port 1 is now closed
2296    EAL: Releasing pci mapped resource for 0002:03:00.0
2297    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2298    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2299    Device 0002:03:00.0 is detached
2300    Now total ports is 1
2301
2302For example, to detach a port created by pcap PMD.
2303
2304.. code-block:: console
2305
2306    testpmd> device detach net_pcap0
2307    Removing a device...
2308    Port 0 is now closed
2309    Device net_pcap0 is detached
2310    Now total ports is 0
2311    Done
2312
2313In this case, identifier is ``net_pcap0``.
2314This identifier format is the same as ``--vdev`` format of DPDK applications.
2315

2884Congestion Management
2885---------------------
2886
2887Get capabilities
2888~~~~~~~~~~~~~~~~
2889
2890Retrieve congestion management capabilities supported by driver for given port.
2891Below example command retrieves capabilities for port 0::
2892
2893   testpmd> show port cman capa 0
2894
2895Get configuration
2896~~~~~~~~~~~~~~~~~
2897

2912
2913Filter Functions
2914----------------
2915
2916This section details the available filter functions that are available.
2917
2918Note these functions interface the deprecated legacy filtering framework,
2919superseded by *rte_flow*. See `Flow rules management`_.
2920
2921.. _testpmd_rte_flow:
2922
2923Flow rules management
2924---------------------
2925
2926Control of the generic flow API (*rte_flow*) is fully exposed through the
2927``flow`` command (configuration, validation, creation, destruction, queries
2928and operation modes).
2929
2930Considering *rte_flow* overlaps with all `Filter Functions`_, using both
2931features simultaneously may cause undefined side-effects and is therefore
2932not recommended.
2933
2934``flow`` syntax
2935~~~~~~~~~~~~~~~
2936
2937Because the ``flow`` command uses dynamic tokens to handle the large number
2938of possible flow rules combinations, its behavior differs slightly from
2939other commands, in particular:
2940
2941- Pressing *?* or the *<tab>* key displays contextual help for the current
2942  token, not that of the entire command.
2943
2944- Optional and repeated parameters are supported (provided they are listed
2945  in the contextual help).
2946
2947The first parameter stands for the operation mode. Possible operations and
2948their general syntax are described below. They are covered in detail in the

3257It is bound to ``rte_flow_push()``::
3258
3259   flow push {port_id} queue {queue_id}
3260
3261If successful, it will show::
3262
3263   Queue #[...] operations pushed
3264
3265The usual error message is shown when operations cannot be pushed::
3266
3267   Caught error type [...] ([...]): [...]
3268
3269Pulling flow operations results
3270~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3271
3272``flow pull`` asks the underlying device about flow queue operations
3273results and return all the processed (successfully or not) operations.
3274It is bound to ``rte_flow_pull()``::
3275
3276   flow pull {port_id} queue {queue_id}
3277
3278If successful, it will show::
3279
3280   Queue #[...] pulled #[...] operations (#[...] failed, #[...] succeeded)
3281
3282The usual error message is shown when operations results cannot be pulled::
3283
3284   Caught error type [...] ([...]): [...]
3285
3286Creating a tunnel stub for offload
3287~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3288
3289``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3290
3291   flow tunnel create {port_id} type {tunnel_type}
3292
3293If successful, it will return a tunnel stub ID usable with other commands::
3294
3295   port [...]: flow tunnel #[...] type [...]
3296
3297Tunnel stub ID is relative to a port.
3298
3299Destroying tunnel offload stub
3300~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3301
3302``flow tunnel destroy`` destroy port tunnel stub::
3303
3304   flow tunnel destroy {port_id} id {tunnel_id}
3305
3306Listing tunnel offload stubs
3307~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3308
3309``flow tunnel list`` list port tunnel offload stubs::
3310
3311   flow tunnel list {port_id}
3312
3313Validating flow rules
3314~~~~~~~~~~~~~~~~~~~~~
3315
3316``flow validate`` reports whether a flow rule would be accepted by the
3317underlying device in its current state but stops short of creating it. It is
3318bound to ``rte_flow_validate()``::
3319
3320   flow validate {port_id}
3321      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3322      pattern {item} [/ {item} [...]] / end
3323      actions {action} [/ {action} [...]] / end
3324
3325If successful, it will show::
3326
3327   Flow rule validated
3328
3329Otherwise it will show an error message of the form::
3330
3331   Caught error type [...] ([...]): [...]
3332
3333This command uses the same parameters as ``flow create``, their format is
3334described in `Creating flow rules`_.
3335
3336Check whether redirecting any Ethernet packet received on port 0 to RX queue
3337index 6 is supported::
3338
3339   testpmd> flow validate 0 ingress pattern eth / end
3340      actions queue index 6 / end
3341   Flow rule validated
3342   testpmd>
3343
3344Port 0 does not support TCPv6 rules::
3345
3346   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3347      actions drop / end
3348   Caught error type 9 (specific pattern item): Invalid argument
3349   testpmd>
3350
3351Creating flow rules
3352~~~~~~~~~~~~~~~~~~~
3353
3354``flow create`` validates and creates the specified flow rule. It is bound
3355to ``rte_flow_create()``::
3356
3357   flow create {port_id}
3358      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3359      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3360      [user_id {user_id}] pattern {item} [/ {item} [...]] / end
3361      actions {action} [/ {action} [...]] / end
3362
3363If successful, it will return a flow rule ID usable with other commands::
3364
3365   Flow rule #[...] created
3366
3367Or if ``user_id`` is provided::
3368
3369   Flow rule #[...] created, user-id [...]
3370
3371Otherwise it will show an error message of the form::
3372
3373   Caught error type [...] ([...]): [...]
3374
3375Parameters describe in the following order:
3376
3377- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3378- Tunnel offload specification (tunnel_set, tunnel_match)
3379- User identifier for the flow.
3380- A matching pattern, starting with the *pattern* token and terminated by an
3381  *end* pattern item.
3382- Actions, starting with the *actions* token and terminated by an *end*
3383  action.
3384
3385These translate directly to *rte_flow* objects provided as-is to the
3386underlying functions.
3387
3388The shortest valid definition only comprises mandatory tokens::
3389
3390   testpmd> flow create 0 pattern end actions end
3391
3392Note that PMDs may refuse rules that essentially do nothing such as this
3393one.
3394
3395**All unspecified object values are automatically initialized to 0.**
3396
3397Enqueueing creation of flow rules
3398~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3399
3400``flow queue create`` adds creation operation of a flow rule to a queue.
3401It is bound to ``rte_flow_async_create()``::
3402
3403   flow queue {port_id} create {queue_id}
3404       [postpone {boolean}] template_table {table_id}
3405       pattern_template {pattern_template_index}
3406       actions_template {actions_template_index}
3407       pattern {item} [/ {item} [...]] / end
3408       actions {action} [/ {action} [...]] / end
3409
3410If successful, it will return a flow rule ID usable with other commands::
3411
3412   Flow rule #[...] creaion enqueued
3413
3414Otherwise it will show an error message of the form::
3415
3416   Caught error type [...] ([...]): [...]
3417
3418This command uses the same pattern items and actions as ``flow create``,
3419their format is described in `Creating flow rules`_.
3420
3421``flow queue pull`` must be called to retrieve the operation status.
3422
3423Attributes
3424^^^^^^^^^^
3425
3426These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3427specified before the ``pattern`` token.
3428
3429- ``group {group id}``: priority group.
3430- ``priority {level}``: priority level within group.
3431- ``ingress``: rule applies to ingress traffic.
3432- ``egress``: rule applies to egress traffic.
3433- ``transfer``: apply rule directly to endpoints found in pattern.
3434
3435Please note that use of ``transfer`` attribute requires that the flow and
3436its indirect components be managed via so-called ``transfer`` proxy port.
3437See `show flow transfer proxy port ID for the given port`_ for details.
3438
3439Each instance of an attribute specified several times overrides the previous
3440value as shown below (group 4 is used)::
3441
3442   testpmd> flow create 0 group 42 group 24 group 4 [...]
3443
3444Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3445
3446While not specifying a direction is an error, some rules may allow both
3447simultaneously.
3448
3449Most rules affect RX therefore contain the ``ingress`` token::
3450
3451   testpmd> flow create 0 ingress pattern [...]
3452
3453Tunnel offload
3454^^^^^^^^^^^^^^
3455
3456Indicate tunnel offload rule type
3457
3458- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3459- ``tunnel_match {tunnel_id}``:  mark rule as tunnel offload match type.
3460
3461Matching pattern
3462^^^^^^^^^^^^^^^^
3463
3464A matching pattern starts after the ``pattern`` token. It is made of pattern
3465items and is terminated by a mandatory ``end`` item.
3466
3467Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3468rte_flow_item_type``).
3469
3470The ``/`` token is used as a separator between pattern items as shown
3471below::
3472
3473   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3474
3475Note that protocol items like these must be stacked from lowest to highest
3476layer to make sense. For instance, the following rule is either invalid or
3477unlikely to match any packet::
3478
3479   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3480
3481More information on these restrictions can be found in the *rte_flow*
3482documentation.
3483
3484Several items support additional specification structures, for example
3485``ipv4`` allows specifying source and destination addresses as follows::
3486
3487   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3488      dst is 10.2.0.0 / end [...]
3489
3490This rule matches all IPv4 traffic with the specified properties.
3491
3492In this example, ``src`` and ``dst`` are field names of the underlying
3493``struct rte_flow_item_ipv4`` object. All item properties can be specified
3494in a similar fashion.
3495
3496The ``is`` token means that the subsequent value must be matched exactly,
3497and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3498accordingly. Possible assignment tokens are:
3499
3500- ``is``: match value perfectly (with full bit-mask).
3501- ``spec``: match value according to configured bit-mask.
3502- ``last``: specify upper bound to establish a range.
3503- ``mask``: specify bit-mask with relevant bits set to one.
3504- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3505
3506These yield identical results::
3507
3508   ipv4 src is 10.1.1.1
3509
3510::
3511
3512   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3513
3514::
3515
3516   ipv4 src spec 10.1.1.1 src prefix 32
3517
3518::
3519
3520   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3521
3522::
3523
3524   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3525
3526Inclusive ranges can be defined with ``last``::
3527
3528   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3529
3530Note that ``mask`` affects both ``spec`` and ``last``::
3531
3532   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3533      # matches 10.1.0.0 to 10.2.255.255
3534
3535Properties can be modified multiple times::
3536
3537   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3538
3539::
3540
3541   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3542

3823Actions list
3824^^^^^^^^^^^^
3825
3826A list of actions starts after the ``actions`` token in the same fashion as
3827`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3828terminated by a mandatory ``end`` action.
3829
3830Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3831rte_flow_action_type``).
3832
3833Dropping all incoming UDPv4 packets can be expressed as follows::
3834
3835   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3836      actions drop / end
3837
3838Several actions have configurable properties which must be specified when
3839there is no valid default value. For example, ``queue`` requires a target
3840queue index.
3841
3842This rule redirects incoming UDPv4 traffic to queue index 6::
3843
3844   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3845      actions queue index 6 / end
3846
3847While this one could be rejected by PMDs (unspecified queue index)::
3848
3849   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3850      actions queue / end
3851
3852As defined by *rte_flow*, the list is not ordered, all actions of a given
3853rule are performed simultaneously. These are equivalent::
3854
3855   queue index 6 / void / mark id 42 / end
3856
3857::
3858
3859   void / mark id 42 / queue index 6 / end
3860
3861All actions in a list should have different types, otherwise only the last
3862action of a given type is taken into account::
3863
3864   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3865
3866::
3867
3868   drop / drop / drop / end # drop is performed only once
3869
3870::
3871
3872   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3873
3874Considering they are performed simultaneously, opposite and overlapping
3875actions can sometimes be combined when the end result is unambiguous::
3876
3877   drop / queue index 6 / end # drop has no effect
3878
3879::
3880
3881   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3882
3883::
3884
3885   drop / passthru / end # drop has no effect
3886
3887Note that PMDs may still refuse such combinations.

4111Destroying flow rules
4112~~~~~~~~~~~~~~~~~~~~~
4113
4114``flow destroy`` destroys one or more rules from their rule ID (as returned
4115by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4116times as necessary::
4117
4118   flow destroy {port_id} rule {rule_id} [...] [user_id]
4119
4120If successful, it will show::
4121
4122   Flow rule #[...] destroyed
4123
4124Or if ``user_id`` flag is provided::
4125
4126   Flow rule #[...] destroyed, user-id [...]
4127
4128Optional ``user_id`` is a flag that signifies the rule ID
4129is the one provided by the user at creation.
4130It does not report anything for rule IDs that do not exist. The usual error
4131message is shown when a rule cannot be destroyed::
4132
4133   Caught error type [...] ([...]): [...]
4134
4135``flow flush`` destroys all rules on a device and does not take extra
4136arguments. It is bound to ``rte_flow_flush()``::
4137
4138   flow flush {port_id}
4139
4140Any errors are reported as above.
4141
4142Creating several rules and destroying them::
4143
4144   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4145      actions queue index 2 / end
4146   Flow rule #0 created
4147   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4148      actions queue index 3 / end
4149   Flow rule #1 created
4150   testpmd> flow destroy 0 rule 0 rule 1
4151   Flow rule #1 destroyed
4152   Flow rule #0 destroyed
4153   testpmd>
4154
4155The same result can be achieved using ``flow flush``::
4156
4157   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4158      actions queue index 2 / end
4159   Flow rule #0 created
4160   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4161      actions queue index 3 / end
4162   Flow rule #1 created
4163   testpmd> flow flush 0
4164   testpmd>
4165
4166Non-existent rule IDs are ignored::
4167
4168   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4169      actions queue index 2 / end
4170   Flow rule #0 created
4171   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4172      actions queue index 3 / end
4173   Flow rule #1 created
4174   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4175   testpmd>
4176   testpmd> flow destroy 0 rule 0
4177   Flow rule #0 destroyed
4178   testpmd>
4179
4180Enqueueing destruction of flow rules
4181~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4182
4183``flow queue destroy`` adds destruction operations to destroy one or more rules
4184from their rule ID (as returned by ``flow queue create``) to a queue,
4185this command calls ``rte_flow_async_destroy()`` as many times as necessary::
4186
4187   flow queue {port_id} destroy {queue_id}
4188        [postpone {boolean}] rule {rule_id} [...]
4189
4190If successful, it will show::
4191
4192   Flow rule #[...] destruction enqueued
4193
4194It does not report anything for rule IDs that do not exist. The usual error
4195message is shown when a rule cannot be destroyed::
4196
4197   Caught error type [...] ([...]): [...]
4198
4199``flow queue pull`` must be called to retrieve the operation status.
4200
4201Querying flow rules
4202~~~~~~~~~~~~~~~~~~~
4203
4204``flow query`` queries a specific action of a flow rule having that
4205ability. Such actions collect information that can be reported using this
4206command. It is bound to ``rte_flow_query()``::
4207
4208   flow query {port_id} {rule_id} {action} [user_id]
4209
4210Optional ``user_id`` is a flag that signifies the rule ID
4211is the one provided by the user at creation.
4212If successful, it will display either the retrieved data for known actions
4213or the following message::
4214
4215   Cannot display result for action type [...] ([...])
4216
4217Otherwise, it will complain either that the rule does not exist or that some
4218error occurred::
4219
4220   Flow rule #[...] not found
4221
4222::
4223
4224   Caught error type [...] ([...]): [...]
4225
4226Currently only the ``count`` action is supported. This action reports the
4227number of packets that hit the flow rule and the total number of bytes. Its
4228output has the following format::
4229
4230   count:
4231    hits_set: [...] # whether "hits" contains a valid value
4232    bytes_set: [...] # whether "bytes" contains a valid value
4233    hits: [...] # number of packets
4234    bytes: [...] # number of bytes
4235
4236Querying counters for TCPv6 packets redirected to queue 6::
4237
4238   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4239      actions queue index 6 / count / end
4240   Flow rule #4 created
4241   testpmd> flow query 0 4 count
4242   count:
4243    hits_set: 1
4244    bytes_set: 0
4245    hits: 386446
4246    bytes: 0
4247   testpmd>
4248
4249Listing flow rules
4250~~~~~~~~~~~~~~~~~~
4251
4252``flow list`` lists existing flow rules sorted by priority and optionally
4253filtered by group identifiers::
4254
4255   flow list {port_id} [group {group_id}] [...]
4256
4257This command only fails with the following message if the device does not
4258exist::
4259
4260   Invalid port [...]
4261
4262Output consists of a header line followed by a short description of each
4263flow rule, one per line. There is no output at all when no flow rules are
4264configured on the device::
4265
4266   ID      Group   Prio    Attr    Rule
4267   [...]   [...]   [...]   [...]   [...]
4268
4269``Attr`` column flags:
4270
4271- ``i`` for ``ingress``.
4272- ``e`` for ``egress``.
4273
4274Creating several flow rules and listing them::
4275
4276   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4277      actions queue index 6 / end
4278   Flow rule #0 created
4279   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4280      actions queue index 2 / end
4281   Flow rule #1 created
4282   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4283      actions rss queues 6 7 8 end / end
4284   Flow rule #2 created
4285   testpmd> flow list 0
4286   ID      Group   Prio    Attr    Rule
4287   0       0       0       i-      ETH IPV4 => QUEUE
4288   1       0       0       i-      ETH IPV6 => QUEUE
4289   2       0       5       i-      ETH IPV4 UDP => RSS
4290   testpmd>
4291
4292Rules are sorted by priority (i.e. group ID first, then priority level)::
4293
4294   testpmd> flow list 1
4295   ID      Group   Prio    Attr    Rule
4296   0       0       0       i-      ETH => COUNT
4297   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4298   5       0       1000    i-      ETH IPV6 ICMP => QUEUE

4316Toggling isolated mode
4317~~~~~~~~~~~~~~~~~~~~~~
4318
4319``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4320must only be injected from the defined flow rules; that no default traffic
4321is expected outside those rules and the driver is free to assign more
4322resources to handle them. It is bound to ``rte_flow_isolate()``::
4323
4324 flow isolate {port_id} {boolean}
4325
4326If successful, enabling or disabling isolated mode shows either::
4327
4328 Ingress traffic on port [...]
4329    is now restricted to the defined flow rules
4330
4331Or::
4332
4333 Ingress traffic on port [...]
4334    is not restricted anymore to the defined flow rules
4335
4336Otherwise, in case of error::
4337
4338   Caught error type [...] ([...]): [...]
4339
4340Mainly due to its side effects, PMDs supporting this mode may not have the
4341ability to toggle it more than once without reinitializing affected ports
4342first (e.g. by exiting testpmd).
4343
4344Enabling isolated mode::
4345
4346 testpmd> flow isolate 0 true
4347 Ingress traffic on port 0 is now restricted to the defined flow rules
4348 testpmd>
4349
4350Disabling isolated mode::
4351
4352 testpmd> flow isolate 0 false
4353 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4354 testpmd>
4355
4356Dumping HW internal information
4357~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4358
4359``flow dump`` dumps the hardware's internal representation information of
4360all flows. It is bound to ``rte_flow_dev_dump()``::
4361
4362   flow dump {port_id} {output_file} [user_id]
4363
4364If successful, it will show::
4365
4366   Flow dump finished
4367
4368Otherwise, it will complain error occurred::
4369
4370   Caught error type [...] ([...]): [...]
4371
4372Optional ``user_id`` is a flag that signifies the rule ID
4373is the one provided by the user at creation.
4374
4375Listing and destroying aged flow rules
4376~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4377
4378``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4379and ``destroy`` parameter can be used to destroy those flow rules in PMD::
4380
4381   flow aged {port_id} [destroy]
4382
4383Listing current aged flow rules::
4384
4385   testpmd> flow aged 0
4386   Port 0 total aged flows: 0
4387   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4388      actions age timeout 5 / queue index 0 /  end
4389   Flow rule #0 created
4390   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4391      actions age timeout 4 / queue index 0 /  end

4398   Flow rule #3 created
4399
4400
4401Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4402information, all the aged flows are sorted by the longest timeout time. For example, if
4403those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4404will be ID 3, ID 1, ID 0::
4405
4406   testpmd> flow aged 0
4407   Port 0 total aged flows: 4

4748Sample VXLAN flow rules
4749~~~~~~~~~~~~~~~~~~~~~~~
4750
4751Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4752filter on a port::
4753
4754  testpmd> rx_vxlan_port add 4789 0
4755
4756Create VXLAN rules on port 0 to steer traffic to PF queues.

5165Need to construct the connection context with provided information.
5166In the first table, create a flow rule by using conntrack action and jump to
5167the next table. In the next table, create a rule to check the state.
5168
5169::
5170
5171 testpmd> set conntrack com peer 1 is_orig 1 enable 1 live 1 sack 1 cack 0
5172        last_dir 0 liberal 0 state 1 max_ack_win 7 r_lim 5 last_win 510
5173        last_seq 2632987379 last_ack 2532480967 last_end 2632987379
5174        last_index 0x8
5175 testpmd> set conntrack orig scale 7 fin 0 acked 1 unack_data 0
5176        sent_end 2632987379 reply_end 2633016339 max_win 28960
5177        max_ack 2632987379
5178 testpmd> set conntrack rply scale 7 fin 0 acked 1 unack_data 0
5179        sent_end 2532480967 reply_end 2532546247 max_win 65280
5180        max_ack 2532480967
5181 testpmd> flow indirect_action 0 create ingress action conntrack / end
5182 testpmd> flow create 0 group 3 ingress pattern eth / ipv4 / tcp / end actions indirect 0 / jump group 5 / end
5183 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
5184
5185Construct the conntrack again with only "is_orig" set to 0 (other fields are
5186ignored), then use "update" interface to update the direction. Create flow
5187rules like above for the peer port.
5188
5189::
5190
5191 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end
5192
5193Sample meter with policy rules
5194~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5195
5196Meter with policy rules can be created by the following commands:
5197
5198Need to create policy first and actions are set for green/yellow/red colors.
5199Create meter with policy id. Create flow with meter id.
5200
5201Example for policy with meter color action. The purpose is to color the packet
5202to reflect the meter color result.
5203The meter policy action list: ``green -> green, yellow -> yellow, red -> red``.
5204

5265BPF Functions
5266--------------
5267
5268The following sections show functions to load/unload eBPF based filters.
5269
5270bpf-load
5271~~~~~~~~
5272
5273Load an eBPF program as a callback for particular RX/TX queue::
5274
5275   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5276
5277The available load-flags are:
5278
5279* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5280
5281* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5282
5283* ``-``: none.
5284
5285.. note::
5286
5287   You'll need clang v3.7 or above to build bpf program you'd like to load
5288
5289For example:
5290
5291.. code-block:: console
5292
5293   cd examples/bpf
5294   clang -O2 -target bpf -c t1.c
5295
5296Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5297
5298.. code-block:: console
5299
5300   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5301
5302To load (not JITed) t1.o at TX queue 0, port 0:
5303
5304.. code-block:: console
5305
5306   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5307
5308bpf-unload
5309~~~~~~~~~~
5310
5311Unload previously loaded eBPF program for particular RX/TX queue::
5312
5313   testpmd> bpf-unload rx|tx (portid) (queueid)
5314
5315For example to unload BPF filter from TX queue 0, port 0:
5316
5317.. code-block:: console
5318
5319   testpmd> bpf-unload tx 0 0
5320
5321Flex Item Functions
5322-------------------
5323
5324The following sections show functions that configure and create flex item object,
5325create flex pattern and use it in a flow rule.
5326The commands will use 20 bytes IPv4 header for examples:
5327
5328::
5329
5330   0                   1                   2                   3

5345Create flex item
5346~~~~~~~~~~~~~~~~
5347
5348Flex item object is created by PMD according to a new header configuration. The
5349header configuration is compiled by the testpmd and stored in
5350``rte_flow_item_flex_conf`` type variable.
5351
5352::
5353
5354   # flow flex_item create <port> <flex id> <configuration file>
5355   testpmd> flow flex_item init 0 3 ipv4_flex_config.json
5356   port-0: created flex item #3
5357
5358Flex item configuration is kept in external JSON file.
5359It describes the following header elements:
5360
5361**New header length.**
5362
5363Specify whether the new header has fixed or variable length and the basic/minimal
5364header length value.
5365
5366If header length is not fixed, header location with a value that completes header
5367length calculation and scale/offset function must be added.
5368
5369Scale function depends on port hardware.
5370
5371**Next protocol.**
5372
5373Describes location in the new header that specify following network header type.
5374
5375**Flow match samples.**
5376
5377Describes locations in the new header that will be used in flow rules.
5378
5379Number of flow samples and sample maximal length depend of port hardware.
5380
5381**Input trigger.**
5382
5383Describes preceding network header configuration.
5384
5385**Output trigger.**
5386
5387Describes conditions that trigger transfer to following network header
5388
5389.. code-block:: json

5412Flex pattern and flow rules
5413~~~~~~~~~~~~~~~~~~~~~~~~~~~
5414
5415Flex pattern describe parts of network header that will trigger flex flow item hit in a flow rule.
5416Flex pattern directly related to flex item samples configuration.
5417Flex pattern can be shared between ports.
5418
5419**Flex pattern and flow rule to match IPv4 version and 20 bytes length**
5420
5421::
5422
5423   # set flex_pattern <pattern_id> is <hex bytes sequence>
5424   testpmd> flow flex_item pattern 5 is 45FF
5425   created pattern #5
5426
5427   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 5 / end actions mark id 1 / queue index 0 / end
5428   Flow rule #0 created
5429
5430**Flex pattern and flow rule to match packets with source address 1.2.3.4**
5431
5432::
5433
5434   testpmd> flow flex_item pattern 2 spec 45000000000000000000000001020304 mask FF0000000000000000000000FFFFFFFF
