31 Testpmd Runtime Functions
32 =========================
34 Where the testpmd application is started in interactive mode, (-i|--interactive),
35 it displays a prompt that can be used to start and stop forwarding,
36 configure the application, display statistics, set the Flow Director and other tasks.
38 .. code-block:: console
42 The testpmd prompt has some, limited, readline support.
43 Common bash command- line functions such as Ctrl+a and Ctrl+e to go to the start and end of the prompt line are supported
44 as well as access to the command history via the up-arrow.
46 There is also support for tab completion.
47 If you type a partial command and hit <TAB> you get a list of the available completions:
49 .. code-block:: console
51 testpmd> show port <TAB>
53 info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap X
54 info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
55 stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap X
56 stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
62 The testpmd has on-line help for the functions that are available at runtime.
63 These are divided into sections and can be accessed using help, help section or help all:
65 .. code-block:: console
69 Help is available for the following sections:
70 help control : Start and stop forwarding.
71 help display : Displaying port, stats and config information.

255 Configuration Functions
256 -----------------------
258 The testpmd application can be configured from the runtime as well as from the command-line.
260 This section details the available configuration functions that are available.
264 Configuration changes only become active when forwarding is started/restarted.
269 Reset forwarding to the default configuration:
276 Set the debug verbosity level:
280 Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).
285 Set the number of ports used by the application:
289 This is equivalent to the --nb-ports command-line option.
294 Set the number of cores used by the application:
298 This is equivalent to the --nb-cores command-line option.
302 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
307 Set the forwarding cores hexadecimal mask:
311 This is equivalent to the --coremask command-line option.
315 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
320 Set the forwarding ports hexadecimal mask:
324 This is equivalent to the --portmask command-line option.
329 Set number of packets per burst:
333 This is equivalent to the --burst command-line option.
335 In mac_retry forwarding mode, the transmit delay time and number of retries can also be set.
337 set burst tx delay (micrseconds) retry (num)
342 Set the length of each segment of the TX-ONLY packets:
346 Where x[,y]* represents a CSV list of values, without white space.
351 Set the list of forwarding cores:
353 set corelist (x[,y]*)
355 For example, to change the forwarding cores:
357 .. code-block:: console
359 testpmd> set corelist 3,1
360 testpmd> show config fwd
362 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
363 Logical Core 3 (socket 0) forwards packets on 1 streams:
364 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
365 Logical Core 1 (socket 0) forwards packets on 1 streams:
366 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
370 The cores are used in the same order as specified on the command line.
375 Set the list of forwarding ports:
377 set portlist (x[,y]*)
379 For example, to change the port forwarding:
381 .. code-block:: console
383 testpmd> set portlist 0,2,1,3
384 testpmd> show config fwd
386 io packet forwarding - ports=4 - cores=1 - streams=4
387 Logical Core 3 (socket 0) forwards packets on 4 streams:
388 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
389 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
390 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
391 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02
396 Set the VLAN strip on a port:
398 vlan set strip (on|off) (port_id)
403 Set the VLAN strip for a queue on a port:
405 vlan set stripq (on|off) (port_id,queue_id)
410 Set the VLAN filter on a port:
412 vlan set filter (on|off) (port_id)
417 Set the VLAN QinQ (extended queue in queue) on for a port:
419 vlan set qinq (on|off) (port_id)
424 Set the outer VLAN TPID for packet filtering on a port:
426 vlan set tpid (value) (port_id)
430 TPID value must be a 16-bit number (value <= 65536).
435 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID:
437 rx_vlan add (vlan_id|all) (port_id)
441 VLAN filter must be set on that port. VLAN ID < 4096.
442 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
443 in VFTA table. This is important if enabling all vlan_ids.
448 Remove a VLAN ID, or all identifiers, from the set of VLAN identifiers filtered by port ID:
450 rx_vlan rm (vlan_id|all) (port_id)
455 Add a VLAN ID, to the set of VLAN identifiers filtered for VF(s) for port ID:
457 rx_vlan add (vlan_id) port (port_id) vf (vf_mask)
462 Remove a VLAN ID, from the set of VLAN identifiers filtered for VF(s) for port ID:
464 rx_vlan rm (vlan_id) port (port_id) vf (vf_mask)
469 Set the outer VLAN TPID for packet filtering on a port:
471 rx_vlan set tpid (value) (port_id)
476 Add a tunnel filter on a port:
478 tunnel_filter add (port_id) (outer_mac) (inner_mac) (ip_addr) (inner_vlan)
479 (tunnel_type) (filter_type) (tenant_id) (queue_id)
484 Remove a tunnel filter on a port:
486 tunnel_filter rm (port_id) (outer_mac) (inner_mac) (ip_addr) (inner_vlan)
487 (tunnel_type) (filter_type) (tenant_id) (queue_id)
492 Add an UDP port for VXLAN packet filter on a port:
494 rx_vxlan_port add (udp_port) (port_id)
499 Remove an UDP port for VXLAN packet filter on a port:
501 rx_vxlan_port rm (udp_port) (port_id)
506 Set hardware insertion of VLAN IDs in packets sent on a port:
508 tx_vlan set (port_id) vlan_id[, vlan_id_outer]
510 .. code-block:: console
512 Set a single VLAN ID (5) insertion on port 0.
516 Set double VLAN ID (inner: 2, outer: 3) insertion on port 1.
523 Set port based hardware insertion of VLAN ID in packets sent on a port:
525 tx_vlan set pvid (port_id) (vlan_id) (on|off)
530 Disable hardware insertion of a VLAN header in packets sent on a port:
532 tx_vlan reset (port_id)
537 Select hardware or software calculation of the checksum when
538 transmitting a packet using the csum forward engine:
540 csum set (ip|udp|tcp|sctp|outer-ip) (hw|sw) (port_id)
542 - ip|udp|tcp|sctp always concern the inner layer.
544 - outer-ip concerns the outer IP layer in case the packet is recognized
545 as a tunnel packet by the forward engine (vxlan, gre and ipip are
546 supported). See "csum parse-tunnel" command.
550 Check the NIC Datasheet for hardware limits.
555 Define how tunneled packets should be handled by the csum forward
558 csum parse-tunnel (on|off) (tx_port_id)
560 If enabled, the csum forward engine will try to recognize supported
561 tunnel headers (vxlan, gre, ipip).
563 If disabled, treat tunnel packets as non-tunneled packets (a inner
564 header is handled as a packet payload).
568 The port argument is the TX port like in the "csum set" command.
572 Consider a packet as following:
573 "eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in"
575 - If parse-tunnel is enabled, the ip|udp|tcp|sctp parameters of "csum
576 set" command are about inner headers (here ipv4_in and tcp_in), and the
577 outer-ip parameter is about outer headers (here ipv4_out).
579 - If parse-tunnel is disabled, the ip|udp|tcp|sctp parameters of "csum
580 set" command are about outer headers, here ipv4_out and udp_out.
585 Display tx checksum offload configuration:
592 Enable TCP Segmentation Offload in csum forward engine:
594 tso set (segsize) (port_id)
598 Check the NIC datasheet for hardware limits
603 Display the status of TCP Segmentation Offload:
610 Set the packet forwarding mode:
612 set fwd (io|mac|mac_retry|macswap|flowgen|rxonly|txonly|csum|icmpecho)
614 The available information categories are:
616 * io: forwards packets "as-is" in I/O mode.
617 This is the fastest possible forwarding operation as it does not access packets data.
618 This is the default mode.
620 * mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
622 * mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
624 * macswap: MAC swap forwarding mode.
625 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
627 * flowgen: multi-flow generation mode.
628 Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
630 * rxonly: receives packets but doesn't transmit them.
632 * txonly: generates and transmits packets without receiving any.
634 * csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
636 * icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
641 .. code-block:: console
643 testpmd> set fwd rxonly
645 Set rxonly packet forwarding mode
650 Add an alternative MAC address to a port:
652 mac_addr add (port_id) (XX:XX:XX:XX:XX:XX)

671 Set the unicast hash filter(s) on/off for a port X:
673 set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off)
678 Set the promiscuous mode on for a port or for all ports.
679 In promiscuous mode packets are not dropped if they aren't for the specified MAC address:
681 set promisc (port_id|all) (on|off)
686 Set the allmulti mode for a port or for all ports:
688 set allmulti (port_id|all) (on|off)
690 Same as the ifconfig (8) option. Controls how multicast packets are handled.

697 set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
698 (pause_time) (send_xon) (port_id)
702 high_water (integer): High threshold value to trigger XOFF.
704 low_water (integer) : Low threshold value to trigger XON.
706 pause_time (integer): Pause quota in the Pause frame.
708 send_xon (0/1) : Send XON frame.

726 Set statistics mapping (qmapping 0..15) for RX/TX queue on port:
728 set stat_qmap (tx|rx) (port_id) (queue_id) (qmapping)
730 For example, to set rx queue 2 on port 0 to mapping 5:
732 .. code-block:: console
734 testpmd>set stat_qmap rx 0 2 5
736 set port - rx/tx(for VF)
737 ~~~~~~~~~~~~~~~~~~~~~~~~
739 Set VF receive/transmit from a port:
741 set port (port_id) vf (vf_id) (rx|tx) (on|off)
743 set port - mac address filter (for VF)

782 set port - mirror rule
783 ~~~~~~~~~~~~~~~~~~~~~~
785 Set pool or vlan type mirror rule for a port:
787 set port (port_id) mirror-rule (rule_id) (pool-mirror-up|pool-mirror-down|vlan-mirror) (poolmask|vlanid[,vlanid]*) dst-pool (pool_id) (on|off)
789 Set link mirror rule for a port:
791 set port (port_id) mirror-rule (rule_id) (uplink-mirror|downlink-mirror) dst-pool (pool_id) (on|off)
793 For example to enable mirror traffic with vlan 0,1 to pool 0:
795 .. code-block:: console
797 set port 0 mirror-rule 0 vlan-mirror 0,1 dst-pool 0 on
799 reset port - mirror rule
800 ~~~~~~~~~~~~~~~~~~~~~~~~
802 Reset a mirror rule for a port.
804 reset port (port_id) mirror-rule (rule_id)
809 Flush (default) or don't flush RX streams before forwarding.
810 Mainly used with PCAP drivers to avoid the default behavior of flushing the first 512 packets on RX streams.
817 Set the bypass mode for the lowest port on bypass enabled NIC.
819 set bypass mode (normal|bypass|isolate) (port_id)
824 Set the event required to initiate specified bypass mode for the lowest port on a bypass enabled NIC where:

855 Set link up for a port.
857 set link-up port (port id)
862 Set link down for a port.
864 set link-down port (port id)
869 The following sections show functions for configuring ports.
873 Port configuration changes only become active when forwarding is started/restarted.
878 Attach a port specified by pci address or virtual device args.
880 To attach a new pci device, the device should be recognized by kernel first.
881 Then it should be moved under DPDK management.
882 Finally the port can be attached to testpmd.
883 On the other hand, to attach a port created by virtual device, above steps are not needed.
885 port attach (identifier)
887 For example, to attach a port whose pci address is 0000:02:00.0.
889 .. code-block:: console
891 testpmd> port attach 0000:02:00.0
892 Attaching a new port...
894 Port 0 is attached. Now total ports is 1
897 For example, to attach a port created by pcap PMD.
899 .. code-block:: console
901 testpmd> port attach eth_pcap0,iface=eth0
902 Attaching a new port...
904 Port 0 is attached. Now total ports is 1
907 In this case, identifier is "eth_pcap0,iface=eth0".
908 This identifier format is the same as "--vdev" format of DPDK applications.
913 Detach a specific port.
915 Before detaching a port, the port should be closed.
916 Also to remove a pci device completely from the system, first detach the port from testpmd.
917 Then the device should be moved under kernel management.
918 Finally the device can be removed using kernel pci hotplug functionality.
919 On the other hand, to remove a port created by a virtual device, above steps are not needed.
921 port detach (port_id)
923 For example, to detach a port 0.
925 .. code-block:: console
927 testpmd> port detach 0
935 Start all ports or a specific port:
937 port start (port_id|all)

954 ~~~~~~~~~~~~~~~~~~~~~
956 Start/stop a rx/tx queue on a specific port:
958 port (port_id) (rxq|txq) (queue_id) (start|stop)
960 Only take effect when port is started.
965 Set the speed and duplex mode for all ports or a specific port:
967 port config (port_id|all) speed (10|100|1000|10000|auto) duplex (half|full|auto)
969 port config - queues/descriptors
970 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
972 Set number of queues/descriptors for rxq, txq, rxd and txd:
974 port config all (rxq|txq|rxd|txd) (value)
976 This is equivalent to the --rxq, --txq, --rxd and --txd command-line options.
978 port config - max-pkt-len
979 ~~~~~~~~~~~~~~~~~~~~~~~~~
981 Set the maximum packet length:
983 port config all max-pkt-len (value)
985 This is equivalent to the --max-pkt-len command-line option.
987 port config - CRC Strip
988 ~~~~~~~~~~~~~~~~~~~~~~~
990 Set hardware CRC stripping on or off for all ports:
992 port config all crc-strip (on|off)
994 CRC stripping is off by default.
996 The on option is equivalent to the --crc-strip command-line option.
998 port config - RX Checksum
999 ~~~~~~~~~~~~~~~~~~~~~~~~~
1001 Set hardware RX checksum offload to on or off for all ports:
1003 port config all rx-cksum (on|off)
1005 Checksum offload is off by default.
1007 The on option is equivalent to the --enable-rx-cksum command-line option.
1012 Set hardware VLAN on or off for all ports:
1014 port config all hw-vlan (on|off)
1016 Hardware VLAN is on by default.
1018 The off option is equivalent to the --disable-hw-vlan command-line option.
1020 port config - VLAN filter
1021 ~~~~~~~~~~~~~~~~~~~~~~~~~
1023 Set hardware VLAN filter on or off for all ports:
1025 port config all hw-vlan-filter (on|off)
1027 Hardware VLAN filter is on by default.
1029 The off option is equivalent to the --disable-hw-vlan-filter command-line option.
1031 port config - VLAN strip
1032 ~~~~~~~~~~~~~~~~~~~~~~~~
1034 Set hardware VLAN strip on or off for all ports:
1036 port config all hw-vlan-strip (on|off)
1038 Hardware VLAN strip is on by default.

1128 Link Bonding Functions
1129 ----------------------
1131 The Link Bonding functions make it possible to dynamically create and
1132 manage link bonding devices from within testpmd interactive prompt.
1134 create bonded device
1135 ~~~~~~~~~~~~~~~~~~~~
1137 Create a new bonding device:
1139 create bonded device (mode) (socket)
1141 For example, to create a bonded device in mode 1 on socket 0.
1143 .. code-block:: console
1145 testpmd> create bonded 1 0
1146 created new bonded device (port X)
1151 Adds Ethernet device to a Link Bonding device:
1153 add bonding slave (slave id) (port id)
1155 For example, to add Ethernet device (port 6) to a Link Bonding device (port 10).
1157 .. code-block:: console
1159 testpmd> add bonding slave 6 10
1162 remove bonding slave
1163 ~~~~~~~~~~~~~~~~~~~~
1165 Removes an Ethernet slave device from a Link Bonding device:
1167 remove bonding slave (slave id) (port id)
1169 For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10).
1171 .. code-block:: console
1173 testpmd> remove bonding slave 6 10
1178 Set the Link Bonding mode of a Link Bonding device:
1180 set bonding mode (value) (port id)
1182 For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3).
1184 .. code-block:: console
1186 testpmd> set bonding mode 3 10
1191 Set an Ethernet slave device as the primary device on a Link Bonding device:
1193 set bonding primary (slave id) (port id)
1195 For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10).
1197 .. code-block:: console
1199 testpmd> set bonding primary 6 10
1204 Set the MAC address of a Link Bonding device:
1206 set bonding mac (port id) (mac)
1208 For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01
1210 .. code-block:: console
1212 testpmd> set bonding mac 10 00:00:00:00:00:01
1214 set bonding xmit_balance_policy
1215 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1217 Set the transmission policy for a Link Bonding device when it is in Balance XOR mode:
1219 set bonding xmit_balance_policy (port_id) (l2|l23|l34)
1221 For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports )
1223 .. code-block:: console
1225 testpmd> set bonding xmit_balance_policy 10 l34
1228 set bonding mon_period
1229 ~~~~~~~~~~~~~~~~~~~~~~
1231 Set the link status monitoring polling period in milliseconds for a bonding device.
1233 This adds support for PMD slave devices which do not support link status interrupts.
1234 When the mon_period is set to a value greater than 0 then all PMD's which do not support
1235 link status ISR will be queried every polling interval to check if their link status has changed.
1237 set bonding mon_period (port_id) (value)
1239 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms
1241 .. code-block:: console

1255 in balance mode with a transmission policy of layer 2+3.
1257 .. code-block:: console
1259 testpmd> show bonding config 9
1261 Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
1263 Active Slaves (3): [1 3 4]
1269 The Register functions can be used to read from and write to registers on the network card referenced by a port number.
1270 This is mainly useful for debugging purposes.
1271 Reference should be made to the appropriate datasheet for the network card for details on the register addresses
1272 and fields that can be accessed.
1277 Display the value of a port register:
1279 read reg (port_id) (address)
1281 For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:
1283 .. code-block:: console
1285 testpmd> read reg 0 0xEE00
1286 port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
1291 Display a port register bit field:
1293 read regfield (port_id) (address) (bit_x) (bit_y)
1295 For example, reading the lowest two bits from the register in the example above:
1297 .. code-block:: console
1299 testpmd> read regfield 0 0xEE00 0 1
1300 port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)
1305 Display a single port register bit:
1307 read regbit (port_id) (address) (bit_x)
1309 For example, reading the lowest bit from the register in the example above:
1311 .. code-block:: console
1313 testpmd> read regbit 0 0xEE00 0
1314 port 0 PCI register at offset 0xEE00: bit 0=1
1319 Set the value of a port register:
1321 write reg (port_id) (address) (value)
1323 For example, to clear a register:
1325 .. code-block:: console
1327 testpmd> write reg 0 0xEE00 0x0
1328 port 0 PCI register at offset 0xEE00: 0x00000000 (0)
1333 Set bit field of a port register:
1335 write regfield (port_id) (address) (bit_x) (bit_y) (value)
1337 For example, writing to the register cleared in the example above:
1339 .. code-block:: console
1341 testpmd> write regfield 0 0xEE00 0 1 2
1342 port 0 PCI register at offset 0xEE00: 0x00000002 (2)
1347 Set single bit value of a port register:
1349 write regbit (port_id) (address) (bit_x) (value)
1351 For example, to set the high bit in the register from the example above:
1353 .. code-block:: console
1355 testpmd> write regbit 0 0xEE00 31 1
1356 port 0 PCI register at offset 0xEE00: 0x8000000A (2147483658)

1520 flow_director_filter
1521 ~~~~~~~~~~~~~~~~~~~~
1523 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
1525 Two types of filtering are supported which are referred to as Perfect Match and Signature filters, the match mode
1526 is set by the --pkt-filter-mode command-line parameter:
1528 * Perfect match filters.
1529 The hardware checks a match between the masked fields of the received packets and the programmed filters.
1531 * Signature filters.
1532 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
1534 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
1535 per flow type and the flexible payload. The Flow Director can also mask out parts of all of these fields so that filters
1536 are only applied to certain fields or parts of the fields.
1538 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
