6 Testpmd Runtime Functions
7 =========================
9 Where the testpmd application is started in interactive mode, (``-i|--interactive``),
10 it displays a prompt that can be used to start and stop forwarding,
11 configure the application, display statistics (including the extended NIC
12 statistics aka xstats) , set the Flow Director and other tasks::
16 The testpmd prompt has some, limited, readline support.
17 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
18 as well as access to the command history via the up-arrow.
20 There is also support for tab completion.
21 If you type a partial command and hit ``<TAB>`` you get a list of the available completions:
23 .. code-block:: console
25 testpmd> show port <TAB>
27 info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap X
28 info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap all
29 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap X
30 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap all
36 Some examples in this document are too long to fit on one line are are shown wrapped at `"\\"` for display purposes::
38 testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
39 (pause_time) (send_xon) (port_id)
41 In the real ``testpmd>`` prompt these commands should be on a single line.
46 The testpmd has on-line help for the functions that are available at runtime.
47 These are divided into sections and can be accessed using help, help section or help all:
49 .. code-block:: console
53 help control : Start and stop forwarding.
54 help display : Displaying port, stats and config information.
55 help config : Configuration information.
56 help ports : Configuring ports.
57 help registers : Reading and setting port registers.
58 help filters : Filters configuration help.
59 help all : All of the above sections.
62 Command File Functions
63 ----------------------
65 To facilitate loading large number of commands or to avoid cutting and pasting where not
66 practical or possible testpmd supports alternative methods for executing commands.
68 * If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
69 will execute all CLI commands contained within the file immediately before
70 starting packet forwarding or entering interactive mode.
72 .. code-block:: console
74 ./testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt
75 Interactive-mode selected

90 Flow rule #499 created
91 Read all CLI commands from /home/ubuntu/flow-create-commands.txt
95 * At run-time additional commands can be loaded in bulk by invoking the ``load FILENAME``
98 .. code-block:: console
100 testpmd> load /home/ubuntu/flow-create-commands.txt
105 Flow rule #498 created
106 Flow rule #499 created
107 Read all CLI commands from /home/ubuntu/flow-create-commands.txt
111 In all cases output from any included command will be displayed as standard output.
112 Execution will continue until the end of the file is reached regardless of
113 whether any errors occur. The end user must examine the output to determine if
114 any failures occurred.
123 Start packet forwarding with current configuration::
130 Start packet forwarding with current configuration after sending specified number of bursts of packets::
132 testpmd> start tx_first (""|burst_num)
134 The default burst number is 1 when ``burst_num`` not presented.
139 Stop packet forwarding, and display accumulated statistics::
154 The functions in the following sections are used to display information about the
155 testpmd configuration or the NIC status.
160 Display information for a given port or all ports::
162 testpmd> show port (info|summary|stats|xstats|fdir|stat_qmap|dcb_tc|cap) (port_id|all)
164 The available information categories are:
166 * ``info``: General port information such as MAC address.
168 * ``summary``: Brief port summary such as Device Name, Driver Name etc.
170 * ``stats``: RX/TX statistics.
172 * ``xstats``: RX/TX extended NIC statistics.
174 * ``fdir``: Flow Director information and statistics.
176 * ``stat_qmap``: Queue statistics mapping.
178 * ``dcb_tc``: DCB information such as TC mapping.

199 Maximum number of MAC addresses of hash filtering: 0
204 Redirection table size: 512
205 Supported flow types:
225 Display the rss redirection table entry indicated by masks on port X::
227 testpmd> show port (port_id) rss reta (size) (mask0, mask1...)
229 size is used to indicate the hardware supported reta size
234 Display the RSS hash functions and RSS hash key of a port::
236 testpmd> show port (port_id) rss-hash [key]
241 Clear the port statistics for a given port or for all ports::

247 testpmd> clear port stats all
252 Display information for a given port's RX/TX queue::
254 testpmd> show (rxq|txq) info (port_id) (queue_id)
259 Displays the configuration of the application.
260 The configuration comes from the command-line, the runtime or the application defaults::
262 testpmd> show config (rxtx|cores|fwd|txpkts)
264 The available information categories are:
266 * ``rxtx``: RX/TX configuration items.
268 * ``cores``: List of forwarding cores.
270 * ``fwd``: Packet forwarding configuration.
272 * ``txpkts``: Packets to TX configuration.
276 .. code-block:: console
278 testpmd> show config rxtx
280 io packet forwarding - CRC stripping disabled - packets/burst=16
281 nb forwarding cores=2 - nb forwarding ports=1
282 RX queues=1 - RX desc=128 - RX free threshold=0
283 RX threshold registers: pthresh=8 hthresh=8 wthresh=4
284 TX queues=1 - TX desc=512 - TX free threshold=0
285 TX threshold registers: pthresh=36 hthresh=0 wthresh=0
286 TX RS bit threshold=0 - TXQ flags=0x0
291 Set the packet forwarding mode::
293 testpmd> set fwd (io|mac|macswap|flowgen| \
294 rxonly|txonly|csum|icmpecho|noisy) (""|retry)
296 ``retry`` can be specified for forwarding engines except ``rx_only``.
298 The available information categories are:
300 * ``io``: Forwards packets "as-is" in I/O mode.
301 This is the fastest possible forwarding operation as it does not access packets data.
302 This is the default mode.
304 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
305 Default application behaviour is to set source Ethernet address to that of the transmitting interface, and destination
306 address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
307 'eth-peer-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
309 * ``macswap``: MAC swap forwarding mode.
310 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
312 * ``flowgen``: Multi-flow generation mode.
313 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
315 * ``rxonly``: Receives packets but doesn't transmit them.
317 * ``txonly``: Generates and transmits packets without receiving any.
319 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
321 * ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
323 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
325 * ``softnic``: Demonstrates the softnic forwarding operation. In this mode, packet forwarding is
326 similar to I/O mode except for the fact that packets are loopback to the softnic ports only. Therefore, portmask parameter should be set to softnic port only. The various software based custom NIC pipelines specified through the softnic firmware (DPDK packet framework script) can be tested in this mode. Furthermore, it allows to build 5-level hierarchical QoS scheduler as a default option that can be enabled through CLI once testpmd application is initialised. The user can modify the default scheduler hierarchy or can specify the new QoS Scheduler hierarchy through CLI. Requires ``CONFIG_RTE_LIBRTE_PMD_SOFTNIC=y``.
328 * ``noisy``: Noisy neighbour simulation.
329 Simulate more realistic behavior of a guest machine engaged in receiving
330 and sending packets performing Virtual Network Function (VNF).

433 Configuration Functions
434 -----------------------
436 The testpmd application can be configured from the runtime as well as from the command-line.
438 This section details the available configuration functions that are available.
442 Configuration changes only become active when forwarding is started/restarted.
447 Reset forwarding to the default configuration::
454 Set the debug verbosity level::
456 testpmd> set verbose (level)
458 Available levels are as following:
460 * ``0`` silent except for error.
461 * ``1`` fully verbose except for Tx packets.
462 * ``2`` fully verbose except for Rx packets.
463 * ``> 2`` fully verbose.
468 Set the log level for a log type::
470 testpmd> set log global|(type) (level)
474 * ``type`` is the log name.
476 * ``level`` is the log level.
478 For example, to change the global log level::
479 testpmd> set log global (level)
481 Regexes can also be used for type. To change log level of user1, user2 and user3::
482 testpmd> set log user[1-3] (level)
487 Set the number of ports used by the application:
491 This is equivalent to the ``--nb-ports`` command-line option.
496 Set the number of cores used by the application::
498 testpmd> set nbcore (num)
500 This is equivalent to the ``--nb-cores`` command-line option.
504 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
509 Set the forwarding cores hexadecimal mask::
511 testpmd> set coremask (mask)
513 This is equivalent to the ``--coremask`` command-line option.
517 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
522 Set the forwarding ports hexadecimal mask::
524 testpmd> set portmask (mask)
526 This is equivalent to the ``--portmask`` command-line option.
531 Set number of packets per burst::
533 testpmd> set burst (num)
535 This is equivalent to the ``--burst command-line`` option.
537 When retry is enabled, the transmit delay time and number of retries can also be set::
539 testpmd> set burst tx delay (microseconds) retry (num)
544 Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
546 testpmd> set txpkts (x[,y]*)
548 Where x[,y]* represents a CSV list of values, without white space.
553 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
555 testpmd> set txsplit (off|on|rand)
559 * ``off`` disable packet copy & split for CSUM mode.
561 * ``on`` split outgoing packet into multiple segments. Size of each segment
562 and number of segments per packet is determined by ``set txpkts`` command
565 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
570 Set the list of forwarding cores::
572 testpmd> set corelist (x[,y]*)
574 For example, to change the forwarding cores:
576 .. code-block:: console
578 testpmd> set corelist 3,1
579 testpmd> show config fwd
581 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
582 Logical Core 3 (socket 0) forwards packets on 1 streams:
583 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
584 Logical Core 1 (socket 0) forwards packets on 1 streams:
585 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
589 The cores are used in the same order as specified on the command line.
594 Set the list of forwarding ports::
596 testpmd> set portlist (x[,y]*)
598 For example, to change the port forwarding:
600 .. code-block:: console
602 testpmd> set portlist 0,2,1,3
603 testpmd> show config fwd
605 io packet forwarding - ports=4 - cores=1 - streams=4
606 Logical Core 3 (socket 0) forwards packets on 4 streams:
607 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
608 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
609 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
610 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02

643 Enable/disable MACsec offload::
645 testpmd> set macsec offload (port_id) on encrypt (on|off) replay-protect (on|off)
646 testpmd> set macsec offload (port_id) off
651 Configure MACsec secure connection (SC)::
653 testpmd> set macsec sc (tx|rx) (port_id) (mac) (pi)
657 The pi argument is ignored for tx.
658 Check the NIC Datasheet for hardware limits.
663 Configure MACsec secure association (SA)::
665 testpmd> set macsec sa (tx|rx) (port_id) (idx) (an) (pn) (key)

749 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID::
751 testpmd> rx_vlan add (vlan_id|all) (port_id)
755 VLAN filter must be set on that port. VLAN ID < 4096.
756 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
757 in VFTA table. This is important if enabling all vlan_ids.
762 Remove a VLAN ID, or all identifiers, from the set of VLAN identifiers filtered by port ID::

825 imac-tenid|imac|omac-imac-tenid|oip|iip) (tenant_id) (queue_id)
830 Add an UDP port for VXLAN packet filter on a port::
832 testpmd> rx_vxlan_port add (udp_port) (port_id)
837 Remove an UDP port for VXLAN packet filter on a port::
839 testpmd> rx_vxlan_port rm (udp_port) (port_id)
844 Set hardware insertion of VLAN IDs in packets sent on a port::
846 testpmd> tx_vlan set (port_id) vlan_id[, vlan_id_outer]
848 For example, set a single VLAN ID (5) insertion on port 0::
852 Or, set double VLAN ID (inner: 2, outer: 3) insertion on port 1::
860 Set port based hardware insertion of VLAN ID in packets sent on a port::

875 transmitting a packet using the ``csum`` forwarding engine::
877 testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
881 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
883 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
884 as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
885 supported). See also the ``csum parse-tunnel`` command.
887 * ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
888 as a tunnel packet by the forwarding engine (vxlan, vxlan-gpe are
889 supported). See also the ``csum parse-tunnel`` command.
893 Check the NIC Datasheet for hardware limits.
898 Set RSS queue region span on a port::
900 testpmd> set port (port_id) queue-region region_id (value) \
901 queue_start_index (value) queue_num (value)
903 Set flowtype mapping on a RSS queue region on a port::
905 testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
909 * For the flowtype(pctype) of packet,the specific index for each type has
910 been defined in file i40e_type.h as enum i40e_filter_pctype.
912 Set user priority mapping on a RSS queue region on a port::
914 testpmd> set port (port_id) queue-region UP (value) region_id (value)
916 Flush all queue region related configuration on a port::
918 testpmd> set port (port_id) queue-region flush (on|off)
922 * "on"is just an enable function which server for other configuration,
923 it is for all configuration about queue region from up layer,
924 at first will only keep in DPDK softwarestored in driver,
925 only after "flush on", it commit all configuration to HW.
926 "off" is just clean all configuration about queue region just now,
927 and restore all to DPDK i40e driver default config when start up.
929 Show all queue region related configuration info on a port::
931 testpmd> show port (port_id) queue-region
935 Queue region only support on PF by now, so these command is
936 only for configuration of queue region on PF port.
941 Define how tunneled packets should be handled by the csum forward
944 testpmd> csum parse-tunnel (on|off) (tx_port_id)
946 If enabled, the csum forward engine will try to recognize supported
947 tunnel headers (vxlan, gre, ipip).
949 If disabled, treat tunnel packets as non-tunneled packets (a inner
950 header is handled as a packet payload).
954 The port argument is the TX port like in the ``csum set`` command.
958 Consider a packet in packet like the following::
960 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
962 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
963 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
964 ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
966 * If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
967 command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
972 Display tx checksum offload configuration::

979 Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::
981 testpmd> tso set (segsize) (port_id)
985 Check the NIC datasheet for hardware limits.
990 Display the status of TCP Segmentation Offload::
992 testpmd> tso show (port_id)
997 Enable or disable GRO in ``csum`` forwarding engine::
999 testpmd> set port <port_id> gro on|off
1001 If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1002 packets received from the given port.
1004 If disabled, packets received from the given port won't be performed
1005 GRO. By default, GRO is disabled for all ports.
1009 When enable GRO for a port, TCP/IPv4 packets received from the port
1010 will be performed GRO. After GRO, all merged packets have bad
1011 checksums, since the GRO library doesn't re-calculate checksums for
1012 the merged packets. Therefore, if users want the merged packets to
1013 have correct checksums, please select HW IP checksum calculation and
1014 HW TCP checksum calculation for the port which the merged packets are
1020 Display GRO configuration for a given port::
1022 testpmd> show port <port_id> gro
1027 Set the cycle to flush the GROed packets from reassembly tables::
1029 testpmd> set gro flush <cycles>
1031 When enable GRO, the csum forwarding engine performs GRO on received
1032 packets, and the GROed packets are stored in reassembly tables. Users
1033 can use this command to determine when the GROed packets are flushed
1034 from the reassembly tables.
1036 The ``cycles`` is measured in GRO operation times. The csum forwarding
1037 engine flushes the GROed packets from the tables every ``cycles`` GRO
1040 By default, the value of ``cycles`` is 1, which means flush GROed packets
1041 from the reassembly tables as soon as one GRO operation finishes. The value
1042 of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1044 Please note that the large value of ``cycles`` may cause the poor TCP/IP
1045 stack performance. Because the GROed packets are delayed to arrive the
1046 stack, thus causing more duplicated ACKs and TCP retransmissions.
1051 Toggle per-port GSO support in ``csum`` forwarding engine::
1053 testpmd> set port <port_id> gso on|off
1055 If enabled, the csum forwarding engine will perform GSO on supported IPv4
1056 packets, transmitted on the given port.
1058 If disabled, packets transmitted on the given port will not undergo GSO.
1059 By default, GSO is disabled for all ports.
1063 When GSO is enabled on a port, supported IPv4 packets transmitted on that
1064 port undergo GSO. Afterwards, the segmented packets are represented by
1065 multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1066 of checksums for GSO'd segments in SW. As a result, if users want correct
1067 checksums in GSO segments, they should enable HW checksum calculation for
1070 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1071 by setting the following options in the csum forwarding engine:
1073 testpmd> csum set outer_ip hw <port_id>
1075 testpmd> csum set ip hw <port_id>
1077 testpmd> csum set tcp hw <port_id>
1079 UDP GSO is the same as IP fragmentation, which treats the UDP header
1080 as the payload and does not modify it during segmentation. That is,
1081 after UDP GSO, only the first output fragment has the original UDP
1082 header. Therefore, users need to enable HW IP checksum calculation
1083 and SW UDP checksum calculation for GSO-enabled ports, if they want
1084 correct checksums for UDP/IPv4 packets.
1089 Set the maximum GSO segment size (measured in bytes), which includes the
1090 packet header and the packet payload for GSO-enabled ports (global)::

1671 Configure the outer layer to decapsulate MPLSoUDP packet::
1673 set mplsoudp_decap ip-version (ipv4|ipv6)
1674 set mplsoudp_decap-with-vlan ip-version (ipv4|ipv6)
1676 Those command will set an internal configuration inside testpmd, any following
1677 flow rule using the action mplsoudp_decap will use the last configuration set.
1678 To have a different decapsulation header, one of those commands must be called
1679 before the flow rule creation.
1684 The following sections show functions for configuring ports.
1688 Port configuration changes only become active when forwarding is started/restarted.
1693 Attach a port specified by pci address or virtual device args::
1695 testpmd> port attach (identifier)
1697 To attach a new pci device, the device should be recognized by kernel first.
1698 Then it should be moved under DPDK management.
1699 Finally the port can be attached to testpmd.
1701 For example, to move a pci device using ixgbe under DPDK management:
1703 .. code-block:: console
1705 # Check the status of the available devices.
1706 ./usertools/dpdk-devbind.py --status
1708 Network devices using DPDK-compatible driver

1712 Network devices using kernel driver
1713 ===================================
1714 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1717 # Bind the device to igb_uio.
1718 sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1721 # Recheck the status of the devices.
1722 ./usertools/dpdk-devbind.py --status
1723 Network devices using DPDK-compatible driver
1724 ============================================
1725 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1727 To attach a port created by virtual device, above steps are not needed.
1729 For example, to attach a port whose pci address is 0000:0a:00.0.
1731 .. code-block:: console
1733 testpmd> port attach 0000:0a:00.0
1734 Attaching a new port...
1735 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1736 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
1737 EAL: PCI memory mapped at 0x7f83bfa00000
1738 EAL: PCI memory mapped at 0x7f83bfa80000
1739 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1740 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1741 Port 0 is attached. Now total ports is 1
1744 For example, to attach a port created by pcap PMD.
1746 .. code-block:: console
1748 testpmd> port attach net_pcap0
1749 Attaching a new port...
1750 PMD: Initializing pmd_pcap for net_pcap0
1751 PMD: Creating pcap-backed ethdev on numa socket 0
1752 Port 0 is attached. Now total ports is 1
1755 In this case, identifier is ``net_pcap0``.
1756 This identifier format is the same as ``--vdev`` format of DPDK applications.
1758 For example, to re-attach a bonded port which has been previously detached,
1759 the mode and slave parameters must be given.
1761 .. code-block:: console
1763 testpmd> port attach net_bond_0,mode=0,slave=1
1764 Attaching a new port...
1765 EAL: Initializing pmd_bond for net_bond_0
1766 EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1767 Port 0 is attached. Now total ports is 1
1774 Detach a specific port::
1776 testpmd> port detach (port_id)
1778 Before detaching a port, the port should be stopped and closed.
1780 For example, to detach a pci device port 0.
1782 .. code-block:: console
1784 testpmd> port stop 0
1787 testpmd> port close 0
1791 testpmd> port detach 0
1793 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1794 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
1795 EAL: PCI memory unmapped at 0x7f83bfa00000
1796 EAL: PCI memory unmapped at 0x7f83bfa80000
1800 For example, to detach a virtual device port 0.
1802 .. code-block:: console
1804 testpmd> port stop 0
1807 testpmd> port close 0
1811 testpmd> port detach 0
1813 PMD: Closing pcap ethdev on numa socket 0
1814 Port 'net_pcap0' is detached. Now total ports is 0
1817 To remove a pci device completely from the system, first detach the port from testpmd.
1818 Then the device should be moved under kernel management.
1819 Finally the device can be removed using kernel pci hotplug functionality.
1821 For example, to move a pci device under kernel management:
1823 .. code-block:: console
1825 sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1827 ./usertools/dpdk-devbind.py --status

2219 ~~~~~~~~~~~~~~~~~~~~~~
2221 Set the link status monitoring polling period in milliseconds for a bonding device.
2223 This adds support for PMD slave devices which do not support link status interrupts.
2224 When the mon_period is set to a value greater than 0 then all PMD's which do not support
2225 link status ISR will be queried every polling interval to check if their link status has changed::
2227 testpmd> set bonding mon_period (port_id) (value)
2229 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

2264 Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
2266 Active Slaves (3): [1 3 4]
2273 The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
2274 This is mainly useful for debugging purposes.
2275 Reference should be made to the appropriate datasheet for the network card for details on the register addresses
2276 and fields that can be accessed.

3020 .. _testpmd_flow_director:
3022 flow_director_filter
3023 ~~~~~~~~~~~~~~~~~~~~
3025 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
3027 Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
3028 Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
3030 * Perfect match filters.
3031 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3032 The masked fields are for IP flow.
3034 * Signature filters.
3035 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
3037 * Perfect-mac-vlan match filters.
3038 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3039 The masked fields are for MAC VLAN flow.
3041 * Perfect-tunnel match filters.
3042 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3043 The masked fields are for tunnel flow.
3045 * Perfect-raw-flow-type match filters.
3046 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
3047 The masked fields are specified by input sets.
3049 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
3050 per flow type and the flexible payload.
3052 The Flow Director can also mask out parts of all of these fields so that filters
3053 are only applied to certain fields or parts of the fields.
3055 Note that for raw flow type mode the source and destination fields in the
3056 raw packet buffer need to be presented in a reversed order with respect
3057 to the expected received packets.
3058 For example: IP source and destination addresses or TCP/UDP/SCTP
3059 source and destination ports
3061 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

3182 testpmd> flow_director_flex_payload 0 l4 \
3183 (4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)
3185 get_sym_hash_ena_per_port
3186 ~~~~~~~~~~~~~~~~~~~~~~~~~
3188 Get symmetric hash enable configuration per port::
3190 get_sym_hash_ena_per_port (port_id)
3192 For example, to get symmetric hash enable configuration of port 1::
3194 testpmd> get_sym_hash_ena_per_port 1
3196 set_sym_hash_ena_per_port
3197 ~~~~~~~~~~~~~~~~~~~~~~~~~
3199 Set symmetric hash enable configuration per port to enable or disable::

3203 For example, to set symmetric hash enable configuration of port 1 to enable::
3205 testpmd> set_sym_hash_ena_per_port 1 enable
3207 get_hash_global_config
3208 ~~~~~~~~~~~~~~~~~~~~~~
3210 Get the global configurations of hash filters::

3214 For example, to get the global configurations of hash filters of port 1::
3216 testpmd> get_hash_global_config 1
3218 set_hash_global_config

3252 The Flow Director filters can match the different fields for different type of packet, i.e. specific input set
3253 on per flow type and the flexible payload. This command can be used to change input set for each flow type.
3255 Set the input set for flow director::

3280 .. _testpmd_rte_flow:
3282 Flow rules management
3283 ---------------------
3285 Control of the generic flow API (*rte_flow*) is fully exposed through the
3286 ``flow`` command (validation, creation, destruction, queries and operation
3289 Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3290 features simultaneously may cause undefined side-effects and is therefore
3296 Because the ``flow`` command uses dynamic tokens to handle the large number
3297 of possible flow rules combinations, its behavior differs slightly from
3298 other commands, in particular:
3300 - Pressing *?* or the *<tab>* key displays contextual help for the current
3301 token, not that of the entire command.
3303 - Optional and repeated parameters are supported (provided they are listed
3304 in the contextual help).
3306 The first parameter stands for the operation mode. Possible operations and
3307 their general syntax are described below. They are covered in detail in the
3310 - Check whether a flow rule can be created::
3312 flow validate {port_id}
3313 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3314 pattern {item} [/ {item} [...]] / end
3315 actions {action} [/ {action} [...]] / end
3317 - Create a flow rule::
3319 flow create {port_id}
3320 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3321 pattern {item} [/ {item} [...]] / end
3322 actions {action} [/ {action} [...]] / end
3324 - Destroy specific flow rules::
3326 flow destroy {port_id} rule {rule_id} [...]
3328 - Destroy all flow rules::
3330 flow flush {port_id}
3332 - Query an existing flow rule::
3334 flow query {port_id} {rule_id} {action}
3336 - List existing flow rules sorted by priority, filtered by group
3339 flow list {port_id} [group {group_id}] [...]
3341 - Restrict ingress traffic to the defined flow rules::
3343 flow isolate {port_id} {boolean}
3345 Validating flow rules
3346 ~~~~~~~~~~~~~~~~~~~~~
3348 ``flow validate`` reports whether a flow rule would be accepted by the
3349 underlying device in its current state but stops short of creating it. It is
3350 bound to ``rte_flow_validate()``::
3352 flow validate {port_id}
3353 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3354 pattern {item} [/ {item} [...]] / end
3355 actions {action} [/ {action} [...]] / end
3357 If successful, it will show::
3361 Otherwise it will show an error message of the form::
3363 Caught error type [...] ([...]): [...]
3365 This command uses the same parameters as ``flow create``, their format is
3366 described in `Creating flow rules`_.
3368 Check whether redirecting any Ethernet packet received on port 0 to RX queue
3369 index 6 is supported::
3371 testpmd> flow validate 0 ingress pattern eth / end
3372 actions queue index 6 / end
3376 Port 0 does not support TCPv6 rules::
3378 testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3380 Caught error type 9 (specific pattern item): Invalid argument
3386 ``flow create`` validates and creates the specified flow rule. It is bound
3387 to ``rte_flow_create()``::
3389 flow create {port_id}
3390 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3391 pattern {item} [/ {item} [...]] / end
3392 actions {action} [/ {action} [...]] / end
3394 If successful, it will return a flow rule ID usable with other commands::
3396 Flow rule #[...] created
3398 Otherwise it will show an error message of the form::
3400 Caught error type [...] ([...]): [...]
3402 Parameters describe in the following order:
3404 - Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3405 - A matching pattern, starting with the *pattern* token and terminated by an
3407 - Actions, starting with the *actions* token and terminated by an *end*
3410 These translate directly to *rte_flow* objects provided as-is to the
3411 underlying functions.
3413 The shortest valid definition only comprises mandatory tokens::
3415 testpmd> flow create 0 pattern end actions end
3417 Note that PMDs may refuse rules that essentially do nothing such as this
3420 **All unspecified object values are automatically initialized to 0.**
3425 These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3426 specified before the ``pattern`` token.
3428 - ``group {group id}``: priority group.
3429 - ``priority {level}``: priority level within group.
3430 - ``ingress``: rule applies to ingress traffic.
3431 - ``egress``: rule applies to egress traffic.
3432 - ``transfer``: apply rule directly to endpoints found in pattern.
3434 Each instance of an attribute specified several times overrides the previous
3435 value as shown below (group 4 is used)::
3437 testpmd> flow create 0 group 42 group 24 group 4 [...]
3439 Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3441 While not specifying a direction is an error, some rules may allow both
3444 Most rules affect RX therefore contain the ``ingress`` token::
3446 testpmd> flow create 0 ingress pattern [...]
3451 A matching pattern starts after the ``pattern`` token. It is made of pattern
3452 items and is terminated by a mandatory ``end`` item.
3454 Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3455 rte_flow_item_type``).
3457 The ``/`` token is used as a separator between pattern items as shown
3460 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3462 Note that protocol items like these must be stacked from lowest to highest
3463 layer to make sense. For instance, the following rule is either invalid or
3464 unlikely to match any packet::
3466 testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3468 More information on these restrictions can be found in the *rte_flow*
3471 Several items support additional specification structures, for example
3472 ``ipv4`` allows specifying source and destination addresses as follows::
3474 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3475 dst is 10.2.0.0 / end [...]
3477 This rule matches all IPv4 traffic with the specified properties.
3479 In this example, ``src`` and ``dst`` are field names of the underlying
3480 ``struct rte_flow_item_ipv4`` object. All item properties can be specified
3481 in a similar fashion.
3483 The ``is`` token means that the subsequent value must be matched exactly,
3484 and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3485 accordingly. Possible assignment tokens are:
3487 - ``is``: match value perfectly (with full bit-mask).
3488 - ``spec``: match value according to configured bit-mask.
3489 - ``last``: specify upper bound to establish a range.
3490 - ``mask``: specify bit-mask with relevant bits set to one.
3491 - ``prefix``: generate bit-mask from a prefix length.
3493 These yield identical results::
3495 ipv4 src is 10.1.1.1
3499 ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3503 ipv4 src spec 10.1.1.1 src prefix 32
3507 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3511 ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3513 Inclusive ranges can be defined with ``last``::
3515 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3517 Note that ``mask`` affects both ``spec`` and ``last``::
3519 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3520 # matches 10.1.0.0 to 10.2.255.255
3522 Properties can be modified multiple times::
3524 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3528 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3706 A list of actions starts after the ``actions`` token in the same fashion as

3708 terminated by a mandatory ``end`` action.
3710 Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3711 rte_flow_action_type``).
3713 Dropping all incoming UDPv4 packets can be expressed as follows::
3715 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3718 Several actions have configurable properties which must be specified when
3719 there is no valid default value. For example, ``queue`` requires a target
3722 This rule redirects incoming UDPv4 traffic to queue index 6::
3724 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3725 actions queue index 6 / end
3727 While this one could be rejected by PMDs (unspecified queue index)::
3729 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3732 As defined by *rte_flow*, the list is not ordered, all actions of a given
3733 rule are performed simultaneously. These are equivalent::
3735 queue index 6 / void / mark id 42 / end
3739 void / mark id 42 / queue index 6 / end
3741 All actions in a list should have different types, otherwise only the last
3742 action of a given type is taken into account::
3744 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3748 drop / drop / drop / end # drop is performed only once
3752 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3754 Considering they are performed simultaneously, opposite and overlapping
3755 actions can sometimes be combined when the end result is unambiguous::
3757 drop / queue index 6 / end # drop has no effect
3761 queue index 6 / rss queues 6 7 8 / end # queue has no effect
3765 drop / passthru / end # drop has no effect
3767 Note that PMDs may still refuse such combinations.

3946 Destroying flow rules
3947 ~~~~~~~~~~~~~~~~~~~~~
3949 ``flow destroy`` destroys one or more rules from their rule ID (as returned
3950 by ``flow create``), this command calls ``rte_flow_destroy()`` as many
3951 times as necessary::
3953 flow destroy {port_id} rule {rule_id} [...]
3955 If successful, it will show::
3957 Flow rule #[...] destroyed
3959 It does not report anything for rule IDs that do not exist. The usual error
3960 message is shown when a rule cannot be destroyed::
3962 Caught error type [...] ([...]): [...]
3964 ``flow flush`` destroys all rules on a device and does not take extra
3965 arguments. It is bound to ``rte_flow_flush()``::
3967 flow flush {port_id}
3969 Any errors are reported as above.
3971 Creating several rules and destroying them::
3973 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3974 actions queue index 2 / end
3975 Flow rule #0 created
3976 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3977 actions queue index 3 / end
3978 Flow rule #1 created
3979 testpmd> flow destroy 0 rule 0 rule 1
3980 Flow rule #1 destroyed
3981 Flow rule #0 destroyed
3984 The same result can be achieved using ``flow flush``::
3986 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3987 actions queue index 2 / end
3988 Flow rule #0 created
3989 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3990 actions queue index 3 / end
3991 Flow rule #1 created
3992 testpmd> flow flush 0
3995 Non-existent rule IDs are ignored::
3997 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3998 actions queue index 2 / end
3999 Flow rule #0 created
4000 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4001 actions queue index 3 / end
4002 Flow rule #1 created
4003 testpmd> flow destroy 0 rule 42 rule 10 rule 2
4005 testpmd> flow destroy 0 rule 0
4006 Flow rule #0 destroyed
4012 ``flow query`` queries a specific action of a flow rule having that
4013 ability. Such actions collect information that can be reported using this
4014 command. It is bound to ``rte_flow_query()``::
4016 flow query {port_id} {rule_id} {action}
4018 If successful, it will display either the retrieved data for known actions
4019 or the following message::
4021 Cannot display result for action type [...] ([...])
4023 Otherwise, it will complain either that the rule does not exist or that some
4026 Flow rule #[...] not found
4030 Caught error type [...] ([...]): [...]
4032 Currently only the ``count`` action is supported. This action reports the
4033 number of packets that hit the flow rule and the total number of bytes. Its
4034 output has the following format::
4037 hits_set: [...] # whether "hits" contains a valid value
4038 bytes_set: [...] # whether "bytes" contains a valid value
4039 hits: [...] # number of packets
4040 bytes: [...] # number of bytes
4042 Querying counters for TCPv6 packets redirected to queue 6::
4044 testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4045 actions queue index 6 / count / end
4046 Flow rule #4 created
4047 testpmd> flow query 0 4 count
4058 ``flow list`` lists existing flow rules sorted by priority and optionally
4059 filtered by group identifiers::
4061 flow list {port_id} [group {group_id}] [...]
4063 This command only fails with the following message if the device does not
4068 Output consists of a header line followed by a short description of each
4069 flow rule, one per line. There is no output at all when no flow rules are
4070 configured on the device::
4072 ID Group Prio Attr Rule
4073 [...] [...] [...] [...] [...]
4075 ``Attr`` column flags:
4077 - ``i`` for ``ingress``.
4078 - ``e`` for ``egress``.
4080 Creating several flow rules and listing them::
4082 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4083 actions queue index 6 / end
4084 Flow rule #0 created
4085 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4086 actions queue index 2 / end
4087 Flow rule #1 created
4088 testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4089 actions rss queues 6 7 8 end / end
4090 Flow rule #2 created
4091 testpmd> flow list 0
4092 ID Group Prio Attr Rule
4093 0 0 0 i- ETH IPV4 => QUEUE
4094 1 0 0 i- ETH IPV6 => QUEUE
4095 2 0 5 i- ETH IPV4 UDP => RSS
4098 Rules are sorted by priority (i.e. group ID first, then priority level)::
4100 testpmd> flow list 1
4101 ID Group Prio Attr Rule
4102 0 0 0 i- ETH => COUNT
4103 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4104 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4105 1 24 0 i- ETH IPV4 UDP => QUEUE
4106 4 24 10 i- ETH IPV4 TCP => DROP
4107 3 24 20 i- ETH IPV4 => DROP
4108 2 24 42 i- ETH IPV4 UDP => QUEUE
4109 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4112 Output can be limited to specific groups::
4114 testpmd> flow list 1 group 0 group 63
4115 ID Group Prio Attr Rule
4116 0 0 0 i- ETH => COUNT
4117 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4118 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4119 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4122 Toggling isolated mode
4123 ~~~~~~~~~~~~~~~~~~~~~~
4125 ``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4126 must only be injected from the defined flow rules; that no default traffic
4127 is expected outside those rules and the driver is free to assign more
4128 resources to handle them. It is bound to ``rte_flow_isolate()``::
4130 flow isolate {port_id} {boolean}
4132 If successful, enabling or disabling isolated mode shows either::
4134 Ingress traffic on port [...]
4135 is now restricted to the defined flow rules
4139 Ingress traffic on port [...]
4140 is not restricted anymore to the defined flow rules
4142 Otherwise, in case of error::
4144 Caught error type [...] ([...]): [...]
4146 Mainly due to its side effects, PMDs supporting this mode may not have the
4147 ability to toggle it more than once without reinitializing affected ports
4148 first (e.g. by exiting testpmd).
4150 Enabling isolated mode::
4152 testpmd> flow isolate 0 true
4153 Ingress traffic on port 0 is now restricted to the defined flow rules
4156 Disabling isolated mode::
4158 testpmd> flow isolate 0 false
4159 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4162 Sample QinQ flow rules
4163 ~~~~~~~~~~~~~~~~~~~~~~
4165 Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4167 testpmd> port stop 0
4168 testpmd> vlan set qinq on 0
4170 The above command sets the inner and outer TPID's to 0x8100.
4172 To change the TPID's the following commands should be used::
4174 testpmd> vlan set outer tpid 0xa100 0
4175 testpmd> vlan set inner tpid 0x9100 0
4176 testpmd> port start 0
4178 Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4182 testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4183 vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4184 Flow rule #0 validated
4186 testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
4187 vlan tci is 456 / end actions vf id 123 / queue index 0 / end
4188 Flow rule #0 created
4190 testpmd> flow list 0
4191 ID Group Prio Attr Rule
4192 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
4194 Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4198 testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4199 vlan tci is 654 / end actions pf / queue index 0 / end
4200 Flow rule #1 validated
4202 testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
4203 vlan tci is 654 / end actions pf / queue index 1 / end
4204 Flow rule #1 created
4206 testpmd> flow list 0
4207 ID Group Prio Attr Rule
4208 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
4209 1 0 0 i- ETH VLAN VLAN=>PF QUEUE

4380 Sample MPLSoUDP encapsulation rule
4381 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4383 MPLSoUDP encapsulation outer layer has default value pre-configured in testpmd
4384 source code, those can be changed by using the following commands
4386 IPv4 MPLSoUDP outer header::

4418 Sample MPLSoUDP decapsulation rule
4419 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4421 MPLSoUDP decapsulation outer layer has default value pre-configured in testpmd
4422 source code, those can be changed by using the following commands
4424 IPv4 MPLSoUDP outer header::
4426 testpmd> set mplsoudp_decap ip-version ipv4
4427 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / mpls / end actions

4433 testpmd> flow create 0 ingress pattern eth / vlan / ipv4 / udp / mpls / end
4434 actions mplsoudp_decap / l2_encap / end
4436 IPv6 MPLSoUDP outer header::

4451 The following sections show functions to load/unload eBPF based filters.
4456 Load an eBPF program as a callback for partciular RX/TX queue::
4458 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
4460 The available load-flags are:
4462 * ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
4464 * ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
4470 You'll need clang v3.7 or above to build bpf program you'd like to load
4474 .. code-block:: console
4477 clang -O2 -target bpf -c t1.c
4479 Then to load (and JIT compile) t1.o at RX queue 0, port 1::
4481 .. code-block:: console
4483 testpmd> bpf-load rx 1 0 J ./dpdk.org/test/bpf/t1.o
4485 To load (not JITed) t1.o at TX queue 0, port 0::
4487 .. code-block:: console
4489 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
4494 Unload previously loaded eBPF program for partciular RX/TX queue::
4496 testpmd> bpf-unload rx|tx (portid) (queueid)
4498 For example to unload BPF filter from TX queue 0, port 0:
4500 .. code-block:: console
4502 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
