33 Testpmd Runtime Functions
34 =========================
36 Where the testpmd application is started in interactive mode, (``-i|--interactive``),
37 it displays a prompt that can be used to start and stop forwarding,
38 configure the application, display statistics, set the Flow Director and other tasks::
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|dcb_tc X
54 info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap|dcb_tc all
55 stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap|dcb_tc X
56 stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap|dcb_tc all
62 Some examples in this document are too long to fit on one line are are shown wrapped at `"\\"` for display purposes::
64 testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
65 (pause_time) (send_xon) (port_id)
67 In the real ``testpmd>`` prompt these commands should be on a single line.
72 The testpmd has on-line help for the functions that are available at runtime.
73 These are divided into sections and can be accessed using help, help section or help all:
75 .. code-block:: console
79 help control : Start and stop forwarding.
80 help display : Displaying port, stats and config information.
81 help config : Configuration information.
82 help ports : Configuring ports.
83 help registers : Reading and setting port registers.
84 help filters : Filters configuration help.
85 help all : All of the above sections.
94 Start packet forwarding with current configuration::
101 Start packet forwarding with current configuration after sending one burst of packets::
103 testpmd> start tx_first
108 Stop packet forwarding, and display accumulated statistics::
123 The functions in the following sections are used to display information about the
124 testpmd configuration or the NIC status.
129 Display information for a given port or all ports::
131 testpmd> show port (info|stats|fdir|stat_qmap|dcb_tc) (port_id|all)
133 The available information categories are:
135 * ``info``: General port information such as MAC address.
137 * ``stats``: RX/TX statistics.
139 * ``fdir``: Flow Director information and statistics.
141 * ``stat_qmap``: Queue statistics mapping.
143 * ``dcb_tc``: DCB information such as TC mapping.
147 .. code-block:: console
149 testpmd> show port info 0
151 ********************* Infos for port 0 *********************
153 MAC address: XX:XX:XX:XX:XX:XX
155 memory allocation on the socket: 0
157 Link speed: 40000 Mbps
158 Link duplex: full-duplex

168 Supported flow types:
184 Display the rss redirection table entry indicated by masks on port X::
186 testpmd> show port (port_id) rss reta (size) (mask0, mask1...)
188 size is used to indicate the hardware supported reta size
193 Display the RSS hash functions and RSS hash key of a port::
195 testpmd> show port (port_id) rss-hash ipv4|ipv4-frag|ipv4-tcp|ipv4-udp|ipv4-sctp|ipv4-other|ipv6|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp|ipv6-other|l2-payload|ipv6-ex|ipv6-tcp-ex|ipv6-udp-ex [key]
200 Clear the port statistics for a given port or for all ports::
202 testpmd> clear port (info|stats|fdir|stat_qmap) (port_id|all)
206 testpmd> clear port stats all
211 Display information for a given port's RX/TX queue::
213 testpmd> show (rxq|txq) info (port_id) (queue_id)
218 Displays the configuration of the application.
219 The configuration comes from the command-line, the runtime or the application defaults::
221 testpmd> show config (rxtx|cores|fwd|txpkts)
223 The available information categories are:
225 * ``rxtx``: RX/TX configuration items.
227 * ``cores``: List of forwarding cores.
229 * ``fwd``: Packet forwarding configuration.
231 * ``txpkts``: Packets to TX configuration.
235 .. code-block:: console
237 testpmd> show config rxtx
239 io packet forwarding - CRC stripping disabled - packets/burst=16
240 nb forwarding cores=2 - nb forwarding ports=1
241 RX queues=1 - RX desc=128 - RX free threshold=0
242 RX threshold registers: pthresh=8 hthresh=8 wthresh=4
243 TX queues=1 - TX desc=512 - TX free threshold=0
244 TX threshold registers: pthresh=36 hthresh=0 wthresh=0
245 TX RS bit threshold=0 - TXQ flags=0x0
250 Set the packet forwarding mode::
252 testpmd> set fwd (io|mac|mac_retry|macswap|flowgen| \
253 rxonly|txonly|csum|icmpecho)
255 The available information categories are:
257 * ``io``: Forwards packets "as-is" in I/O mode.
258 This is the fastest possible forwarding operation as it does not access packets data.
259 This is the default mode.
261 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
263 * ``mac_retry``: Same as "mac" forwarding mode, but includes retries if the destination queue is full.
265 * ``macswap``: MAC swap forwarding mode.
266 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
268 * ``flowgen``: Multi-flow generation mode.
269 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
271 * ``rxonly``: Receives packets but doesn't transmit them.
273 * ``txonly``: Generates and transmits packets without receiving any.
275 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
277 * ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
279 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
281 Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``.
285 testpmd> set fwd rxonly
287 Set rxonly packet forwarding mode
293 Display an RX descriptor for a port RX queue::
295 testpmd> read rxd (port_id) (queue_id) (rxd_id)
299 testpmd> read rxd 0 0 4
300 0x0000000B - 0x001D0180 / 0x0000000B - 0x001D0180
305 Display a TX descriptor for a port TX queue::
307 testpmd> read txd (port_id) (queue_id) (txd_id)
311 testpmd> read txd 0 0 4
312 0x00000001 - 0x24C3C440 / 0x000F0000 - 0x2330003C
315 Configuration Functions
316 -----------------------
318 The testpmd application can be configured from the runtime as well as from the command-line.
320 This section details the available configuration functions that are available.
324 Configuration changes only become active when forwarding is started/restarted.
329 Reset forwarding to the default configuration::
336 Set the debug verbosity level::
338 testpmd> set verbose (level)
340 Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).
345 Set the number of ports used by the application:
349 This is equivalent to the ``--nb-ports`` command-line option.
354 Set the number of cores used by the application::
356 testpmd> set nbcore (num)
358 This is equivalent to the ``--nb-cores`` command-line option.
362 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
367 Set the forwarding cores hexadecimal mask::
369 testpmd> set coremask (mask)
371 This is equivalent to the ``--coremask`` command-line option.
375 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
380 Set the forwarding ports hexadecimal mask::
382 testpmd> set portmask (mask)
384 This is equivalent to the ``--portmask`` command-line option.
389 Set number of packets per burst::
391 testpmd> set burst (num)
393 This is equivalent to the ``--burst command-line`` option.
395 In ``mac_retry`` forwarding mode, the transmit delay time and number of retries can also be set::
397 testpmd> set burst tx delay (micrseconds) retry (num)
402 Set the length of each segment of the TX-ONLY packets::
404 testpmd> set txpkts (x[,y]*)
406 Where x[,y]* represents a CSV list of values, without white space.
411 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
413 testpmd> set txsplit (off|on|rand)
417 * ``off`` disable packet copy & split for CSUM mode.
419 * ``on`` split outgoing packet into multiple segments. Size of each segment
420 and number of segments per packet is determined by ``set txpkts`` command
423 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
428 Set the list of forwarding cores::
430 testpmd> set corelist (x[,y]*)
432 For example, to change the forwarding cores:
434 .. code-block:: console
436 testpmd> set corelist 3,1
437 testpmd> show config fwd
439 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
440 Logical Core 3 (socket 0) forwards packets on 1 streams:
441 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
442 Logical Core 1 (socket 0) forwards packets on 1 streams:
443 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
447 The cores are used in the same order as specified on the command line.
452 Set the list of forwarding ports::
454 testpmd> set portlist (x[,y]*)
456 For example, to change the port forwarding:
458 .. code-block:: console
460 testpmd> set portlist 0,2,1,3
461 testpmd> show config fwd
463 io packet forwarding - ports=4 - cores=1 - streams=4
464 Logical Core 3 (socket 0) forwards packets on 4 streams:
465 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
466 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
467 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
468 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02
473 Set the VLAN strip on a port::
475 testpmd> vlan set strip (on|off) (port_id)
480 Set the VLAN strip for a queue on a port::
482 testpmd> vlan set stripq (on|off) (port_id,queue_id)
487 Set the VLAN filter on a port::
489 testpmd> vlan set filter (on|off) (port_id)
494 Set the VLAN QinQ (extended queue in queue) on for a port::
496 testpmd> vlan set qinq (on|off) (port_id)
501 Set the inner or outer VLAN TPID for packet filtering on a port::
503 testpmd> vlan set (inner|outer) tpid (value) (port_id)
507 TPID value must be a 16-bit number (value <= 65536).
512 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID::
514 testpmd> rx_vlan add (vlan_id|all) (port_id)
518 VLAN filter must be set on that port. VLAN ID < 4096.
519 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
520 in VFTA table. This is important if enabling all vlan_ids.
525 Remove a VLAN ID, or all identifiers, from the set of VLAN identifiers filtered by port ID::
527 testpmd> rx_vlan rm (vlan_id|all) (port_id)
532 Add a VLAN ID, to the set of VLAN identifiers filtered for VF(s) for port ID::
534 testpmd> rx_vlan add (vlan_id) port (port_id) vf (vf_mask)
539 Remove a VLAN ID, from the set of VLAN identifiers filtered for VF(s) for port ID::
541 testpmd> rx_vlan rm (vlan_id) port (port_id) vf (vf_mask)
546 Add a tunnel filter on a port::
548 testpmd> tunnel_filter add (port_id) (outer_mac) (inner_mac) (ip_addr) \
549 (inner_vlan) (vxlan|nvgre|ipingre) (imac-ivlan|imac-ivlan-tenid|\
550 imac-tenid|imac|omac-imac-tenid|oip|iip) (tenant_id) (queue_id)
552 The available information categories are:
554 * ``vxlan``: Set tunnel type as VXLAN.
556 * ``nvgre``: Set tunnel type as NVGRE.
558 * ``ipingre``: Set tunnel type as IP-in-GRE.
560 * ``imac-ivlan``: Set filter type as Inner MAC and VLAN.
562 * ``imac-ivlan-tenid``: Set filter type as Inner MAC, VLAN and tenant ID.
564 * ``imac-tenid``: Set filter type as Inner MAC and tenant ID.
566 * ``imac``: Set filter type as Inner MAC.
568 * ``omac-imac-tenid``: Set filter type as Outer MAC, Inner MAC and tenant ID.
570 * ``oip``: Set filter type as Outer IP.
572 * ``iip``: Set filter type as Inner IP.
576 testpmd> tunnel_filter add 0 68:05:CA:28:09:82 00:00:00:00:00:00 \
577 192.168.2.2 0 ipingre oip 1 1
579 Set an IP-in-GRE tunnel on port 0, and the filter type is Outer IP.
584 Remove a tunnel filter on a port::
586 testpmd> tunnel_filter rm (port_id) (outer_mac) (inner_mac) (ip_addr) \
587 (inner_vlan) (vxlan|nvgre|ipingre) (imac-ivlan|imac-ivlan-tenid|\
588 imac-tenid|imac|omac-imac-tenid|oip|iip) (tenant_id) (queue_id)
593 Add an UDP port for VXLAN packet filter on a port::
595 testpmd> rx_vxlan_port add (udp_port) (port_id)
600 Remove an UDP port for VXLAN packet filter on a port::
602 testpmd> rx_vxlan_port rm (udp_port) (port_id)
607 Set hardware insertion of VLAN IDs in packets sent on a port::
609 testpmd> tx_vlan set (port_id) vlan_id[, vlan_id_outer]
611 For example, set a single VLAN ID (5) insertion on port 0::
615 Or, set double VLAN ID (inner: 2, outer: 3) insertion on port 1::
623 Set port based hardware insertion of VLAN ID in packets sent on a port::
625 testpmd> tx_vlan set pvid (port_id) (vlan_id) (on|off)
630 Disable hardware insertion of a VLAN header in packets sent on a port::
632 testpmd> tx_vlan reset (port_id)
637 Select hardware or software calculation of the checksum when
638 transmitting a packet using the ``csum`` forwarding engine::
640 testpmd> csum set (ip|udp|tcp|sctp|outer-ip) (hw|sw) (port_id)
644 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
646 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
647 as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
648 supported). See also the ``csum parse-tunnel`` command.
652 Check the NIC Datasheet for hardware limits.
657 Define how tunneled packets should be handled by the csum forward
660 testpmd> csum parse-tunnel (on|off) (tx_port_id)
662 If enabled, the csum forward engine will try to recognize supported
663 tunnel headers (vxlan, gre, ipip).
665 If disabled, treat tunnel packets as non-tunneled packets (a inner
666 header is handled as a packet payload).
670 The port argument is the TX port like in the ``csum set`` command.
674 Consider a packet in packet like the following::
676 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
678 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
679 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
680 ``outer-ip parameter`` relates to the outer headers (here ``ipv4_out``).
682 * If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
683 command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
688 Display tx checksum offload configuration::
690 testpmd> csum show (port_id)
695 Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::
697 testpmd> tso set (segsize) (port_id)
701 Check the NIC datasheet for hardware limits.
706 Display the status of TCP Segmentation Offload::
708 testpmd> tso show (port_id)
713 Add an alternative MAC address to a port::
715 testpmd> mac_addr add (port_id) (XX:XX:XX:XX:XX:XX)
720 Remove a MAC address from a port::

727 Add an alternative MAC address for a VF to a port::
729 testpmd> mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX)
734 Set the unicast hash filter(s) on/off for a port::
736 testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off)
741 Set the promiscuous mode on for a port or for all ports.
742 In promiscuous mode packets are not dropped if they aren't for the specified MAC address::
744 testpmd> set promisc (port_id|all) (on|off)
749 Set the allmulti mode for a port or for all ports::
751 testpmd> set allmulti (port_id|all) (on|off)
753 Same as the ifconfig (8) option. Controls how multicast packets are handled.
758 Set the link flow control parameter on a port::
760 testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
761 (pause_time) (send_xon) mac_ctrl_frame_fwd (on|off) \
762 autoneg (on|off) (port_id)
766 * ``high_water`` (integer): High threshold value to trigger XOFF.
768 * ``low_water`` (integer): Low threshold value to trigger XON.
770 * ``pause_time`` (integer): Pause quota in the Pause frame.
772 * ``send_xon`` (0/1): Send XON frame.
774 * ``mac_ctrl_frame_fwd``: Enable receiving MAC control frames.
776 * ``autoneg``: Change the auto-negotiation para mete.
781 Set the priority flow control parameter on a port::
783 testpmd> set pfc_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
784 (pause_time) (priority) (port_id)

799 Set statistics mapping (qmapping 0..15) for RX/TX queue on port::
801 testpmd> set stat_qmap (tx|rx) (port_id) (queue_id) (qmapping)
803 For example, to set rx queue 2 on port 0 to mapping 5::
805 testpmd>set stat_qmap rx 0 2 5
807 set port - rx/tx (for VF)
808 ~~~~~~~~~~~~~~~~~~~~~~~~~

825 Set the VF receive mode of a port::
827 testpmd> set port (port_id) vf (vf_id) \
828 rxmode (AUPE|ROPE|BAM|MPE) (on|off)
830 The available receive modes are:
832 * ``AUPE``: Accepts untagged VLAN.
834 * ``ROPE``: Accepts unicast hash.
836 * ``BAM``: Accepts broadcast packets.
838 * ``MPE``: Accepts all multicast packets.

872 reset port - mirror rule
873 ~~~~~~~~~~~~~~~~~~~~~~~~
875 Reset a mirror rule for a port::
877 testpmd> reset port (port_id) mirror-rule (rule_id)
882 Set the flush on RX streams before forwarding.
883 The default is flush ``on``.
884 Mainly used with PCAP drivers to turn off the default behavior of flushing the first 512 packets on RX streams::
886 testpmd> set flush_rx off
891 Set the bypass mode for the lowest port on bypass enabled NIC::
893 testpmd> set bypass mode (normal|bypass|isolate) (port_id)
898 Set the event required to initiate specified bypass mode for the lowest port on a bypass enabled::

974 The following sections show functions for configuring ports.
978 Port configuration changes only become active when forwarding is started/restarted.
983 Attach a port specified by pci address or virtual device args.
985 To attach a new pci device, the device should be recognized by kernel first.
986 Then it should be moved under DPDK management.
987 Finally the port can be attached to testpmd.
989 For example, to move a pci device using ixgbe under DPDK management:
991 .. code-block:: console
993 # Check the status of the available devices.
994 ./tools/dpdk_nic_bind.py --status

1005 # Bind the device to igb_uio.
1006 sudo ./tools/dpdk_nic_bind.py -b igb_uio 0000:0a:00.0

1015 To attach a port created by virtual device, above steps are not needed.
1017 port attach (identifier)
1019 For example, to attach a port whose pci address is 0000:0a:00.0.
1021 .. code-block:: console
1023 testpmd> port attach 0000:0a:00.0
1024 Attaching a new port...
1025 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1026 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
1027 EAL: PCI memory mapped at 0x7f83bfa00000
1028 EAL: PCI memory mapped at 0x7f83bfa80000
1029 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1030 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1031 Port 0 is attached. Now total ports is 1
1034 For example, to attach a port created by pcap PMD.
1036 .. code-block:: console
1038 testpmd> port attach eth_pcap0
1039 Attaching a new port...
1040 PMD: Initializing pmd_pcap for eth_pcap0
1041 PMD: Creating pcap-backed ethdev on numa socket 0
1042 Port 0 is attached. Now total ports is 1
1045 In this case, identifier is ``eth_pcap0``.
1046 This identifier format is the same as ``--vdev`` format of DPDK applications.
1048 For example, to re-attach a bonded port which has been previously detached,
1049 the mode and slave parameters must be given.
1051 .. code-block:: console
1053 testpmd> port attach eth_bond_0,mode=0,slave=1
1054 Attaching a new port...
1055 EAL: Initializing pmd_bond for eth_bond_0
1056 EAL: Create bonded device eth_bond_0 on port 0 in mode 0 on socket 0.
1057 Port 0 is attached. Now total ports is 1
1064 Detach a specific port.
1066 Before detaching a port, the port should be closed::
1068 testpmd> port detach (port_id)
1070 For example, to detach a pci device port 0.
1072 .. code-block:: console
1074 testpmd> port close 0
1078 testpmd> port detach 0
1080 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1081 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
1082 EAL: PCI memory unmapped at 0x7f83bfa00000
1083 EAL: PCI memory unmapped at 0x7f83bfa80000
1087 For example, to detach a virtual device port 0.
1089 .. code-block:: console
1091 testpmd> port close 0
1095 testpmd> port detach 0
1097 PMD: Closing pcap ethdev on numa socket 0
1098 Port 'eth_pcap0' is detached. Now total ports is 0
1101 To remove a pci device completely from the system, first detach the port from testpmd.
1102 Then the device should be moved under kernel management.
1103 Finally the device can be removed using kernel pci hotplug functionality.
1105 For example, to move a pci device under kernel management:
1107 .. code-block:: console
1109 sudo ./tools/dpdk_nic_bind.py -b ixgbe 0000:0a:00.0
1111 ./tools/dpdk_nic_bind.py --status

1333 Link Bonding Functions
1334 ----------------------
1336 The Link Bonding functions make it possible to dynamically create and
1337 manage link bonding devices from within testpmd interactive prompt.
1339 create bonded device
1340 ~~~~~~~~~~~~~~~~~~~~
1342 Create a new bonding device::
1344 testpmd> create bonded device (mode) (socket)
1346 For example, to create a bonded device in mode 1 on socket 0::
1348 testpmd> create bonded 1 0
1349 created new bonded device (port X)
1354 Adds Ethernet device to a Link Bonding device::
1356 testpmd> add bonding slave (slave id) (port id)
1358 For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
1360 testpmd> add bonding slave 6 10
1363 remove bonding slave
1364 ~~~~~~~~~~~~~~~~~~~~
1366 Removes an Ethernet slave device from a Link Bonding device::
1368 testpmd> remove bonding slave (slave id) (port id)
1370 For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::
1372 testpmd> remove bonding slave 6 10
1377 Set the Link Bonding mode of a Link Bonding device::
1379 testpmd> set bonding mode (value) (port id)
1381 For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3)::
1383 testpmd> set bonding mode 3 10
1388 Set an Ethernet slave device as the primary device on a Link Bonding device::
1390 testpmd> set bonding primary (slave id) (port id)
1392 For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10)::
1394 testpmd> set bonding primary 6 10
1399 Set the MAC address of a Link Bonding device::
1401 testpmd> set bonding mac (port id) (mac)
1403 For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01::

1412 testpmd> set bonding xmit_balance_policy (port_id) (l2|l23|l34)
1414 For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
1416 testpmd> set bonding xmit_balance_policy 10 l34
1419 set bonding mon_period
1420 ~~~~~~~~~~~~~~~~~~~~~~
1422 Set the link status monitoring polling period in milliseconds for a bonding device.
1424 This adds support for PMD slave devices which do not support link status interrupts.
1425 When the mon_period is set to a value greater than 0 then all PMD's which do not support
1426 link status ISR will be queried every polling interval to check if their link status has changed::
1428 testpmd> set bonding mon_period (port_id) (value)
1430 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::
1432 testpmd> set bonding mon_period 5 150
1438 Show the current configuration of a Link Bonding device::
1440 testpmd> show bonding config (port id)
1443 to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
1444 in balance mode with a transmission policy of layer 2+3::
1446 testpmd> show bonding config 9
1448 Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
1450 Active Slaves (3): [1 3 4]
1457 The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
1458 This is mainly useful for debugging purposes.
1459 Reference should be made to the appropriate datasheet for the network card for details on the register addresses
1460 and fields that can be accessed.

1472 port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
1477 Display a port register bit field::
1479 testpmd> read regfield (port_id) (address) (bit_x) (bit_y)
1481 For example, reading the lowest two bits from the register in the example above::
1483 testpmd> read regfield 0 0xEE00 0 1
1484 port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)

1501 Set the value of a port register::
1503 testpmd> write reg (port_id) (address) (value)
1505 For example, to clear a register::
1507 testpmd> write reg 0 0xEE00 0x0
1508 port 0 PCI register at offset 0xEE00: 0x00000000 (0)
1513 Set bit field of a port register::
1515 testpmd> write regfield (port_id) (address) (bit_x) (bit_y) (value)
1517 For example, writing to the register cleared in the example above::
1519 testpmd> write regfield 0 0xEE00 0 1 2
1520 port 0 PCI register at offset 0xEE00: 0x00000002 (2)
1525 Set single bit value of a port register::
1527 testpmd> write regbit (port_id) (address) (bit_x) (value)
1529 For example, to set the high bit in the register from the example above::
1531 testpmd> write regbit 0 0xEE00 31 1
1532 port 0 PCI register at offset 0xEE00: 0x8000000A (2147483658)

1709 ~~~~~~~~~~~~~~~~~~~~
1711 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
1713 Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
1714 Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
1716 * Perfect match filters.
1717 The hardware checks a match between the masked fields of the received packets and the programmed filters.
1718 The masked fields are for IP flow.
1720 * Signature filters.
1721 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
1723 * Perfect-mac-vlan match filters.
1724 The hardware checks a match between the masked fields of the received packets and the programmed filters.
1725 The masked fields are for MAC VLAN flow.
1727 * Perfect-tunnel match filters.
1728 The hardware checks a match between the masked fields of the received packets and the programmed filters.
1729 The masked fields are for tunnel flow.
1731 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
1732 per flow type and the flexible payload.
1734 The Flow Director can also mask out parts of all of these fields so that filters
1735 are only applied to certain fields or parts of the fields.
1737 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
