+set fwd
+~~~~~~~
+
+Set the packet forwarding mode::
+
+ testpmd> set fwd (io|mac|macswap|flowgen| \
+ rxonly|txonly|csum|icmpecho|noisy) (""|retry)
+
+``retry`` can be specified for forwarding engines except ``rx_only``.
+
+The available information categories are:
+
+* ``io``: Forwards packets "as-is" in I/O mode.
+ This is the fastest possible forwarding operation as it does not access packets data.
+ This is the default mode.
+
+* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
+ Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
+ address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
+ 'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
+
+* ``macswap``: MAC swap forwarding mode.
+ Swaps the source and the destination Ethernet addresses of packets before forwarding them.
+
+* ``flowgen``: Multi-flow generation mode.
+ Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
+
+* ``rxonly``: Receives packets but doesn't transmit them.
+
+* ``txonly``: Generates and transmits packets without receiving any.
+
+* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
+
+* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
+
+* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
+
+* ``softnic``: Demonstrates the softnic forwarding operation. In this mode, packet forwarding is
+ 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``.
+
+* ``noisy``: Noisy neighbor simulation.
+ Simulate more realistic behavior of a guest machine engaged in receiving
+ and sending packets performing Virtual Network Function (VNF).

+
+ testpmd> set fwd rxonly
+
+ Set rxonly packet forwarding mode

-Set the outer VLAN TPID for packet filtering on a port:
-vlan set tpid (value) (port_id)
+Configuration Functions
+-----------------------
+
+The testpmd application can be configured from the runtime as well as from the command-line.
+
+This section details the available configuration functions that are available.
.. note::
- TPID value must be a 16-bit number (value <= 65536).
+ Configuration changes only become active when forwarding is started/restarted.
-rx_vlan add
+set default
~~~~~~~~~~~
-Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID:
+Reset forwarding to the default configuration::
-rx_vlan add (vlan_id|all) (port_id)
+ testpmd> set default
-.. note::
+set verbose
+~~~~~~~~~~~
- VLAN filter must be set on that port. VLAN ID < 4096.
- Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
- in VFTA table. This is important if enabling all vlan_ids.
+Set the debug verbosity level::
-rx_vlan rm
+ testpmd> set verbose (level)
+
+Available levels are as following:
+
+* ``0`` silent except for error.
+* ``1`` fully verbose except for Tx packets.
+* ``2`` fully verbose except for Rx packets.
+* ``> 2`` fully verbose.
+
+set log
+~~~~~~~
+
+Set the log level for a log type::
+
+ testpmd> set log global|(type) (level)
+
+Where:
+
+* ``type`` is the log name.
+
+* ``level`` is the log level.
+
+For example, to change the global log level::
+
+ testpmd> set log global (level)
+
+Regexes can also be used for type. To change log level of user1, user2 and user3::
+
+ testpmd> set log user[1-3] (level)

-tx_vlan set pvid
-~~~~~~~~~~~~~~~~
+Where:
-Set port based hardware insertion of VLAN ID in packets sent on a port:
+* ``off`` disable packet copy & split for CSUM mode.
-tx_vlan set pvid (port_id) (vlan_id) (on|off)
+* ``on`` split outgoing packet into multiple segments. Size of each segment
+ and number of segments per packet is determined by ``set txpkts`` command
+ (see above).
-tx_vlan reset

+.. code-block:: console
-- ip|udp|tcp|sctp always concern the inner layer.
+ testpmd> set corelist 3,1
+ testpmd> show config fwd
-- outer-ip concerns the outer IP layer in case the packet is recognized
- as a tunnel packet by the forward engine (vxlan, gre and ipip are

-engine.
+Set the list of forwarding ports::
-csum parse-tunnel (on|off) (tx_port_id)
+ testpmd> set portlist (x[,y]*)
-If enabled, the csum forward engine will try to recognize supported
-tunnel headers (vxlan, gre, ipip).

-header is handled as a packet payload).
+.. code-block:: console
-.. note::
+ testpmd> set portlist 0,2,1,3
+ testpmd> show config fwd
- The port argument is the TX port like in the "csum set" command.
+ io packet forwarding - ports=4 - cores=1 - streams=4
+ Logical Core 3 (socket 0) forwards packets on 4 streams:

-Example:
+set port setup on
+~~~~~~~~~~~~~~~~~
-Consider a packet as following:
-"eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in"
+Select how to retrieve new ports created after "port attach" command::
-- If parse-tunnel is enabled, the ip|udp|tcp|sctp parameters of "csum
- set" command are about inner headers (here ipv4_in and tcp_in), and the
- outer-ip parameter is about outer headers (here ipv4_out).
+ testpmd> set port setup on (iterator|event)
-- If parse-tunnel is disabled, the ip|udp|tcp|sctp parameters of "csum
- set" command are about outer headers, here ipv4_out and udp_out.
+For each new port, a setup is done.
+It will find the probed ports via RTE_ETH_FOREACH_MATCHING_DEV loop
+in iterator mode, or via RTE_ETH_EVENT_NEW in event mode.

+ at first will only keep in DPDK software stored in driver,
+ only after "flush on", it commit all configuration to HW.
+
+* ``"off``: is just clean all configuration about queue region just now,
+ and restore all to DPDK i40e driver default config when start up.
+
+Show all queue region related configuration info on a port::
+
+ testpmd> show port (port_id) queue-region
+
+.. note::
+
+ Queue region only support on PF by now, so these command is
+ only for configuration of queue region on PF port.
+
+csum parse-tunnel
+~~~~~~~~~~~~~~~~~
+
+Define how tunneled packets should be handled by the csum forward
+engine::
+
+ testpmd> csum parse-tunnel (on|off) (tx_port_id)
+
+If enabled, the csum forward engine will try to recognize supported
+tunnel headers (vxlan, gre, ipip).
+
+If disabled, treat tunnel packets as non-tunneled packets (a inner
+header is handled as a packet payload).
+
+.. note::
+
+ The port argument is the TX port like in the ``csum set`` command.
+
+Example:
+
+Consider a packet in packet like the following::
+
+ eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
+
+* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
+ command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
+ ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
+
+* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
+ command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
+

+
+tunnel tso show
+~~~~~~~~~~~~~~~
+
+Display the status of tunneled TCP Segmentation Offload for a port::
+
+ testpmd> tunnel_tso show (port_id)
+
+set port - gro
+~~~~~~~~~~~~~~
+
+Enable or disable GRO in ``csum`` forwarding engine::
+
+ testpmd> set port <port_id> gro on|off
+
+If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
+packets received from the given port.
+
+If disabled, packets received from the given port won't be performed
+GRO. By default, GRO is disabled for all ports.
+
+.. note::
+
+ When enable GRO for a port, TCP/IPv4 packets received from the port
+ will be performed GRO. After GRO, all merged packets have bad
+ checksums, since the GRO library doesn't re-calculate checksums for
+ the merged packets. Therefore, if users want the merged packets to
+ have correct checksums, please select HW IP checksum calculation and
+ HW TCP checksum calculation for the port which the merged packets are
+ transmitted to.
+
+show port - gro
+~~~~~~~~~~~~~~~
+
+Display GRO configuration for a given port::
+
+ testpmd> show port <port_id> gro
+
+set gro flush
+~~~~~~~~~~~~~
+
+Set the cycle to flush the GROed packets from reassembly tables::
+
+ testpmd> set gro flush <cycles>
+
+When enable GRO, the csum forwarding engine performs GRO on received
+packets, and the GROed packets are stored in reassembly tables. Users
+can use this command to determine when the GROed packets are flushed
+from the reassembly tables.
+
+The ``cycles`` is measured in GRO operation times. The csum forwarding
+engine flushes the GROed packets from the tables every ``cycles`` GRO
+operations.
+
+By default, the value of ``cycles`` is 1, which means flush GROed packets
+from the reassembly tables as soon as one GRO operation finishes. The value
+of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
+
+Please note that the large value of ``cycles`` may cause the poor TCP/IP
+stack performance. Because the GROed packets are delayed to arrive the
+stack, thus causing more duplicated ACKs and TCP retransmissions.
+
+set port - gso
+~~~~~~~~~~~~~~
+
+Toggle per-port GSO support in ``csum`` forwarding engine::
+
+ testpmd> set port <port_id> gso on|off
+
+If enabled, the csum forwarding engine will perform GSO on supported IPv4
+packets, transmitted on the given port.
+
+If disabled, packets transmitted on the given port will not undergo GSO.
+By default, GSO is disabled for all ports.
+
+.. note::
+
+ When GSO is enabled on a port, supported IPv4 packets transmitted on that
+ port undergo GSO. Afterwards, the segmented packets are represented by
+ multi-segment mbufs; however, the csum forwarding engine doesn't calculation
+ of checksums for GSO'd segments in SW. As a result, if users want correct
+ checksums in GSO segments, they should enable HW checksum calculation for
+ GSO-enabled ports.
+
+ For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
+ by setting the following options in the csum forwarding engine:
+
+ testpmd> csum set outer_ip hw <port_id>
+
+ testpmd> csum set ip hw <port_id>
+
+ testpmd> csum set tcp hw <port_id>
+
+ UDP GSO is the same as IP fragmentation, which treats the UDP header
+ as the payload and does not modify it during segmentation. That is,
+ after UDP GSO, only the first output fragment has the original UDP
+ header. Therefore, users need to enable HW IP checksum calculation
+ and SW UDP checksum calculation for GSO-enabled ports, if they want
+ correct checksums for UDP/IPv4 packets.
+
+set gso segsz
+~~~~~~~~~~~~~

+Port Functions
+--------------
+
+The following sections show functions for configuring ports.
+
+.. note::
+
+ Port configuration changes only become active when forwarding is started/restarted.
+
+port attach
+~~~~~~~~~~~
+
+Attach a port specified by pci address or virtual device args::
+
+ testpmd> port attach (identifier)
+
+To attach a new pci device, the device should be recognized by kernel first.
+Then it should be moved under DPDK management.
+Finally the port can be attached to testpmd.
+
+For example, to move a pci device using ixgbe under DPDK management:
+
+.. code-block:: console
+
+ # Check the status of the available devices.
+ ./usertools/dpdk-devbind.py --status
+
+ Network devices using DPDK-compatible driver
+ ============================================
+ <none>
+
+ Network devices using kernel driver
+ ===================================
+ 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
+
+
+ # Bind the device to igb_uio.
+ sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
+
+
+ # Recheck the status of the devices.
+ ./usertools/dpdk-devbind.py --status
+ Network devices using DPDK-compatible driver
+ ============================================
+ 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
+
+To attach a port created by virtual device, above steps are not needed.
+
+For example, to attach a port whose pci address is 0000:0a:00.0.
+
+.. code-block:: console
+
+ testpmd> port attach 0000:0a:00.0
+ Attaching a new port...
+ EAL: PCI device 0000:0a:00.0 on NUMA socket -1
+ EAL: probe driver: 8086:10fb rte_ixgbe_pmd
+ EAL: PCI memory mapped at 0x7f83bfa00000
+ EAL: PCI memory mapped at 0x7f83bfa80000
+ PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
+ PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
+ Port 0 is attached. Now total ports is 1
+ Done
+
+For example, to attach a port created by pcap PMD.
+
+.. code-block:: console
+
+ testpmd> port attach net_pcap0
+ Attaching a new port...
+ PMD: Initializing pmd_pcap for net_pcap0
+ PMD: Creating pcap-backed ethdev on numa socket 0
+ Port 0 is attached. Now total ports is 1
+ Done
+
+In this case, identifier is ``net_pcap0``.
+This identifier format is the same as ``--vdev`` format of DPDK applications.

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

+.. _testpmd_rte_flow:
+
+Flow rules management
+---------------------
+
+Control of the generic flow API (*rte_flow*) is fully exposed through the
+``flow`` command (validation, creation, destruction, queries and operation
+modes).
+
+Considering *rte_flow* overlaps with all `Filter Functions`_, using both
+features simultaneously may cause undefined side-effects and is therefore
+not recommended.
+
+``flow`` syntax
+~~~~~~~~~~~~~~~
+
+Because the ``flow`` command uses dynamic tokens to handle the large number
+of possible flow rules combinations, its behavior differs slightly from
+other commands, in particular:
+
+- Pressing *?* or the *<tab>* key displays contextual help for the current
+ token, not that of the entire command.
-set fwd (io|mac|mac_retry|macswap|flowgen|rxonly|txonly|csum|icmpecho)
+- Optional and repeated parameters are supported (provided they are listed
+ in the contextual help).
-The available information categories are:
+The first parameter stands for the operation mode. Possible operations and
+their general syntax are described below. They are covered in detail in the
+following sections.
-* io: forwards packets "as-is" in I/O mode.
- This is the fastest possible forwarding operation as it does not access packets data.
- This is the default mode.
+- Check whether a flow rule can be created::
-* mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-* mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
+- Create a flow rule::
-* macswap: MAC swap forwarding mode.
- Swaps the source and the destination Ethernet addresses of packets before forwarding them.
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-* flowgen: multi-flow generation mode.
- Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
+- Destroy specific flow rules::
-* rxonly: receives packets but doesn't transmit them.
+ flow destroy {port_id} rule {rule_id} [...]
-* txonly: generates and transmits packets without receiving any.
+- Destroy all flow rules::
-* csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
+ flow flush {port_id}
-* icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
+- Query an existing flow rule::
-* ieee1588: demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
- Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``.
+ flow query {port_id} {rule_id} {action}
-Example:
+- List existing flow rules sorted by priority, filtered by group
+ identifiers::
-.. code-block:: console
+ flow list {port_id} [group {group_id}] [...]
- testpmd> set fwd rxonly
+- Restrict ingress traffic to the defined flow rules::
- Set rxonly packet forwarding mode
+ flow isolate {port_id} {boolean}
-mac_addr add
-~~~~~~~~~~~~
+- Dump internal representation information of all flows in hardware::
-Add an alternative MAC address to a port:
+ flow dump {port_id} {output_file}
-mac_addr add (port_id) (XX:XX:XX:XX:XX:XX)
+Validating flow rules
+~~~~~~~~~~~~~~~~~~~~~
-mac_addr remove
-~~~~~~~~~~~~~~~
+``flow validate`` reports whether a flow rule would be accepted by the
+underlying device in its current state but stops short of creating it. It is
+bound to ``rte_flow_validate()``::
-Remove a MAC address from a port:
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX)
+If successful, it will show::
-mac_addr add(for VF)
-~~~~~~~~~~~~~~~~~~~~
+ Flow rule validated
-Add an alternative MAC address for a VF to a port:
+Otherwise it will show an error message of the form::
-mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX)
+ Caught error type [...] ([...]): [...]
-set port-uta
-~~~~~~~~~~~~
+This command uses the same parameters as ``flow create``, their format is
+described in `Creating flow rules`_.
-Set the unicast hash filter(s) on/off for a port X:
+Check whether redirecting any Ethernet packet received on port 0 to RX queue
+index 6 is supported::
-set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off)
+ testpmd> flow validate 0 ingress pattern eth / end
+ actions queue index 6 / end
+ Flow rule validated
+ testpmd>
-set promisc
-~~~~~~~~~~~
+Port 0 does not support TCPv6 rules::
-Set the promiscuous mode on for a port or for all ports.
-In promiscuous mode packets are not dropped if they aren't for the specified MAC address:
+ testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
+ actions drop / end
+ Caught error type 9 (specific pattern item): Invalid argument
+ testpmd>
-set promisc (port_id|all) (on|off)
+Creating flow rules
+~~~~~~~~~~~~~~~~~~~
-set allmulti
-~~~~~~~~~~~~
+``flow create`` validates and creates the specified flow rule. It is bound
+to ``rte_flow_create()``::
-Set the allmulti mode for a port or for all ports:
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-set allmulti (port_id|all) (on|off)
+If successful, it will return a flow rule ID usable with other commands::
-Same as the ifconfig (8) option. Controls how multicast packets are handled.
+ Flow rule #[...] created
-set flow_ctrl rx
-~~~~~~~~~~~~~~~~
+Otherwise it will show an error message of the form::
-Set the link flow control parameter on a port:
+ Caught error type [...] ([...]): [...]
-set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
-(pause_time) (send_xon) (port_id)
+Parameters describe in the following order:
-Where:
+- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
+- A matching pattern, starting with the *pattern* token and terminated by an
+ *end* pattern item.
+- Actions, starting with the *actions* token and terminated by an *end*
+ action.
-high_water (integer): High threshold value to trigger XOFF.
+These translate directly to *rte_flow* objects provided as-is to the
+underlying functions.
-low_water (integer) : Low threshold value to trigger XON.
+The shortest valid definition only comprises mandatory tokens::
-pause_time (integer): Pause quota in the Pause frame.
+ testpmd> flow create 0 pattern end actions end
-send_xon (0/1) : Send XON frame.
+Note that PMDs may refuse rules that essentially do nothing such as this
+one.
-mac_ctrl_frame_fwd : Enable receiving MAC control frames
+**All unspecified object values are automatically initialized to 0.**
-set pfc_ctrl rx
-~~~~~~~~~~~~~~~
+Attributes
+^^^^^^^^^^
-Set the priority flow control parameter on a port:
+These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
+specified before the ``pattern`` token.
-set pfc_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \ (pause_time) (priority) (port_id)
+- ``group {group id}``: priority group.
+- ``priority {level}``: priority level within group.
+- ``ingress``: rule applies to ingress traffic.
+- ``egress``: rule applies to egress traffic.
+- ``transfer``: apply rule directly to endpoints found in pattern.
-Where:
+Each instance of an attribute specified several times overrides the previous
+value as shown below (group 4 is used)::
-priority (0-7): VLAN User Priority.
+ testpmd> flow create 0 group 42 group 24 group 4 [...]
-set stat_qmap
-~~~~~~~~~~~~~
+Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
-Set statistics mapping (qmapping 0..15) for RX/TX queue on port:
+While not specifying a direction is an error, some rules may allow both
+simultaneously.
-set stat_qmap (tx|rx) (port_id) (queue_id) (qmapping)
+Most rules affect RX therefore contain the ``ingress`` token::
-For example, to set rx queue 2 on port 0 to mapping 5:
+ testpmd> flow create 0 ingress pattern [...]
-.. code-block:: console
+Matching pattern
+^^^^^^^^^^^^^^^^
- testpmd>set stat_qmap rx 0 2 5
+A matching pattern starts after the ``pattern`` token. It is made of pattern
+items and is terminated by a mandatory ``end`` item.
-set port - rx/tx(for VF)
-~~~~~~~~~~~~~~~~~~~~~~~~
+Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
+rte_flow_item_type``).
-Set VF receive/transmit from a port:
+The ``/`` token is used as a separator between pattern items as shown
+below::
-set port (port_id) vf (vf_id) (rx|tx) (on|off)
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
-set port - mac address filter (for VF)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Note that protocol items like these must be stacked from lowest to highest
+layer to make sense. For instance, the following rule is either invalid or
+unlikely to match any packet::
-Add/Remove unicast or multicast MAC addr filter for a VF:
+ testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
-set port (port_id) vf (vf_id) (mac_addr)
- (exact-mac|exact-mac-vlan|hashmac|hashmac-vlan) (on|off)
+More information on these restrictions can be found in the *rte_flow*
+documentation.
-set port - rx mode(for VF)
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+Several items support additional specification structures, for example
+``ipv4`` allows specifying source and destination addresses as follows::
-Set the VF receive mode of a port:
+ testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
+ dst is 10.2.0.0 / end [...]
-set port (port_id) vf (vf_id) rxmode (AUPE|ROPE|BAM|MPE) (on|off)
+This rule matches all IPv4 traffic with the specified properties.
-The available receive modes are:
+In this example, ``src`` and ``dst`` are field names of the underlying
+``struct rte_flow_item_ipv4`` object. All item properties can be specified
+in a similar fashion.
-* AUPE: accepts untagged VLAN.
+The ``is`` token means that the subsequent value must be matched exactly,
+and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
+accordingly. Possible assignment tokens are:
-* ROPE: accepts unicast hash.
+- ``is``: match value perfectly (with full bit-mask).
+- ``spec``: match value according to configured bit-mask.
+- ``last``: specify upper bound to establish a range.
+- ``mask``: specify bit-mask with relevant bits set to one.
+- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
-* BAM: accepts broadcast packets
+These yield identical results::
-* MPE: accepts all multicast packets
+ ipv4 src is 10.1.1.1
-set port - tx_rate (for Queue)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+::
-Set TX rate limitation for queue of a port ID:
+ ipv4 src spec 10.1.1.1 src mask 255.255.255.255

+::
-set port - tx_rate (for VF)

-Set TX rate limitation for queues in VF of a port ID:
+::
-set port (port_id) vf (vf_id) rate (rate_value) queue_mask (queue_mask)

-set port - mirror rule
-~~~~~~~~~~~~~~~~~~~~~~
+::
-Set pool or vlan type mirror rule for a port:
+ ipv4 src is 10.1.1.1 src last 0 # 0 disables range
-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)
+Inclusive ranges can be defined with ``last``::
-Set link mirror rule for a port:
+ ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
-set port (port_id) mirror-rule (rule_id) (uplink-mirror|downlink-mirror) dst-pool (pool_id) (on|off)
+Note that ``mask`` affects both ``spec`` and ``last``::
-For example to enable mirror traffic with vlan 0,1 to pool 0:
+ ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
+ # matches 10.1.0.0 to 10.2.255.255
-.. code-block:: console
+Properties can be modified multiple times::
- set port 0 mirror-rule 0 vlan-mirror 0,1 dst-pool 0 on
+ ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
-reset port - mirror rule
-~~~~~~~~~~~~~~~~~~~~~~~~
+::
-Reset a mirror rule for a port.
+ ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
-reset port (port_id) mirror-rule (rule_id)

+- ``meta``: match application specific metadata.
-port config all (rxq|txq|rxd|txd) (value)
+ - ``data {unsigned}``: metadata value.

+terminated by a mandatory ``end`` action.
-The on option is equivalent to the --enable-rx-cksum command-line option.
+Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
+rte_flow_action_type``).
-port config - VLAN
-~~~~~~~~~~~~~~~~~~
+Dropping all incoming UDPv4 packets can be expressed as follows::
-Set hardware VLAN on or off for all ports:
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions drop / end
-port config all hw-vlan (on|off)
+Several actions have configurable properties which must be specified when
+there is no valid default value. For example, ``queue`` requires a target
+queue index.
-Hardware VLAN is on by default.
+This rule redirects incoming UDPv4 traffic to queue index 6::
-The off option is equivalent to the --disable-hw-vlan command-line option.
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions queue index 6 / end
-port config - VLAN filter
-~~~~~~~~~~~~~~~~~~~~~~~~~
+While this one could be rejected by PMDs (unspecified queue index)::
-Set hardware VLAN filter on or off for all ports:
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions queue / end
-port config all hw-vlan-filter (on|off)
+As defined by *rte_flow*, the list is not ordered, all actions of a given
+rule are performed simultaneously. These are equivalent::
-Hardware VLAN filter is on by default.
+ queue index 6 / void / mark id 42 / end
-The off option is equivalent to the --disable-hw-vlan-filter command-line option.
+::
-port config - VLAN strip
-~~~~~~~~~~~~~~~~~~~~~~~~
+ void / mark id 42 / queue index 6 / end
-Set hardware VLAN strip on or off for all ports:
+All actions in a list should have different types, otherwise only the last
+action of a given type is taken into account::
-port config all hw-vlan-strip (on|off)
+ queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
-Hardware VLAN strip is on by default.
+::
-The off option is equivalent to the --disable-hw-vlan-strip command-line option.
+ drop / drop / drop / end # drop is performed only once
-port config - VLAN extend
-~~~~~~~~~~~~~~~~~~~~~~~~~
+::
-Set hardware VLAN extend on or off for all ports:
+ mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
-port config all hw-vlan-extend (on|off)
+Considering they are performed simultaneously, opposite and overlapping
+actions can sometimes be combined when the end result is unambiguous::
-Hardware VLAN extend is off by default.
+ drop / queue index 6 / end # drop has no effect
-The off option is equivalent to the --disable-hw-vlan-extend command-line option.
+::
-port config - Drop Packets
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+ queue index 6 / rss queues 6 7 8 / end # queue has no effect
-Set packet drop for packets with no descriptors on or off for all ports:
+::
-port config all drop-en (on|off)
+ drop / passthru / end # drop has no effect
-Packet dropping for packets with no descriptors is off by default.
+Note that PMDs may still refuse such combinations.
-The on option is equivalent to the --enable-drop-en command-line option.

+``flow destroy`` destroys one or more rules from their rule ID (as returned
+by ``flow create``), this command calls ``rte_flow_destroy()`` as many
+times as necessary::
-Register Functions
-------------------
+ flow destroy {port_id} rule {rule_id} [...]
-The Register functions can be used to read from and write to registers on the network card referenced by a port number.
-This is mainly useful for debugging purposes.
-Reference should be made to the appropriate datasheet for the network card for details on the register addresses
-and fields that can be accessed.
+If successful, it will show::
-read reg
-~~~~~~~~
+ Flow rule #[...] destroyed
-Display the value of a port register:
+It does not report anything for rule IDs that do not exist. The usual error
+message is shown when a rule cannot be destroyed::
-read reg (port_id) (address)
+ Caught error type [...] ([...]): [...]
-For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:
+``flow flush`` destroys all rules on a device and does not take extra
+arguments. It is bound to ``rte_flow_flush()``::
-.. code-block:: console
+ flow flush {port_id}
- testpmd> read reg 0 0xEE00
- port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
+Any errors are reported as above.
-read regfield
-~~~~~~~~~~~~~
+Creating several rules and destroying them::
-Display a port register bit field:
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 3 / end

+ testpmd> flow destroy 0 rule 0 rule 1
+ Flow rule #1 destroyed
+ Flow rule #0 destroyed
+ testpmd>
-read regfield (port_id) (address) (bit_x) (bit_y)
+The same result can be achieved using ``flow flush``::
-For example, reading the lowest two bits from the register in the example above:
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 3 / end
+ Flow rule #1 created
+ testpmd> flow flush 0
+ testpmd>
-.. code-block:: console

+ testpmd>
+ testpmd> flow destroy 0 rule 0
+ Flow rule #0 destroyed
+ testpmd>
-read regbit
-~~~~~~~~~~~
+Querying flow rules
+~~~~~~~~~~~~~~~~~~~
-Display a single port register bit:
+``flow query`` queries a specific action of a flow rule having that
+ability. Such actions collect information that can be reported using this
+command. It is bound to ``rte_flow_query()``::
-read regbit (port_id) (address) (bit_x)
+ flow query {port_id} {rule_id} {action}
-For example, reading the lowest bit from the register in the example above:
+If successful, it will display either the retrieved data for known actions
+or the following message::
-.. code-block:: console
+ Cannot display result for action type [...] ([...])
- testpmd> read regbit 0 0xEE00 0
- port 0 PCI register at offset 0xEE00: bit 0=1
+Otherwise, it will complain either that the rule does not exist or that some
+error occurred::
-write reg
-~~~~~~~~~
+ Flow rule #[...] not found
-Set the value of a port register:
+::
-write reg (port_id) (address) (value)
+ Caught error type [...] ([...]): [...]
-For example, to clear a register:
+Currently only the ``count`` action is supported. This action reports the
+number of packets that hit the flow rule and the total number of bytes. Its
+output has the following format::
-.. code-block:: console
+ count:
+ hits_set: [...] # whether "hits" contains a valid value
+ bytes_set: [...] # whether "bytes" contains a valid value
+ hits: [...] # number of packets
+ bytes: [...] # number of bytes
- testpmd> write reg 0 0xEE00 0x0
- port 0 PCI register at offset 0xEE00: 0x00000000 (0)
+Querying counters for TCPv6 packets redirected to queue 6::
-write regfield
-~~~~~~~~~~~~~~
+ testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
+ actions queue index 6 / count / end
+ Flow rule #4 created
+ testpmd> flow query 0 4 count
+ count:
+ hits_set: 1
+ bytes_set: 0
+ hits: 386446
+ bytes: 0
+ testpmd>
-Set bit field of a port register:
+Listing flow rules
+~~~~~~~~~~~~~~~~~~
-write regfield (port_id) (address) (bit_x) (bit_y) (value)
+``flow list`` lists existing flow rules sorted by priority and optionally
+filtered by group identifiers::
+
+ flow list {port_id} [group {group_id}] [...]
+
+This command only fails with the following message if the device does not
+exist::
+
+ Invalid port [...]
+
+Output consists of a header line followed by a short description of each
+flow rule, one per line. There is no output at all when no flow rules are
+configured on the device::
+
+ ID Group Prio Attr Rule
+ [...] [...] [...] [...] [...]
+
+``Attr`` column flags:
+
+- ``i`` for ``ingress``.
+- ``e`` for ``egress``.
+
+Creating several flow rules and listing them::
+
+ testpmd> flow create 0 ingress pattern eth / ipv4 / end
+ actions queue index 6 / end
+ Flow rule #0 created
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end
+ actions queue index 2 / end
+ Flow rule #1 created

+ testpmd>
+
+Rules are sorted by priority (i.e. group ID first, then priority level)::
+
+ testpmd> flow list 1
+ ID Group Prio Attr Rule
+ 0 0 0 i- ETH => COUNT
+ 6 0 500 i- ETH IPV6 TCP => DROP COUNT

+ 2 24 42 i- ETH IPV4 UDP => QUEUE
+ 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
+ testpmd>
+
+Output can be limited to specific groups::
+
+ testpmd> flow list 1 group 0 group 63
+ ID Group Prio Attr Rule
+ 0 0 0 i- ETH => COUNT
+ 6 0 500 i- ETH IPV6 TCP => DROP COUNT
+ 5 0 1000 i- ETH IPV6 ICMP => QUEUE
+ 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
+ testpmd>
+
+Toggling isolated mode
+~~~~~~~~~~~~~~~~~~~~~~
-For example, writing to the register cleared in the example above:
+``flow isolate`` can be used to tell the underlying PMD that ingress traffic
+must only be injected from the defined flow rules; that no default traffic
+is expected outside those rules and the driver is free to assign more
+resources to handle them. It is bound to ``rte_flow_isolate()``::
-.. code-block:: console
+ flow isolate {port_id} {boolean}
- testpmd> write regfield 0 0xEE00 0 1 2
- port 0 PCI register at offset 0xEE00: 0x00000002 (2)
+If successful, enabling or disabling isolated mode shows either::
-write regbit
-~~~~~~~~~~~~
+ Ingress traffic on port [...]
+ is now restricted to the defined flow rules
-Set single bit value of a port register:
+Or::
-write regbit (port_id) (address) (bit_x) (value)
+ Ingress traffic on port [...]
+ is not restricted anymore to the defined flow rules
-For example, to set the high bit in the register from the example above:
+Otherwise, in case of error::
-.. code-block:: console
+ Caught error type [...] ([...]): [...]
- testpmd> write regbit 0 0xEE00 31 1
- port 0 PCI register at offset 0xEE00: 0x8000000A (2147483658)
+Mainly due to its side effects, PMDs supporting this mode may not have the
+ability to toggle it more than once without reinitializing affected ports
+first (e.g. by exiting testpmd).
-Filter Functions
-----------------
+Enabling isolated mode::
-This section details the available filter functions that are available.
+ testpmd> flow isolate 0 true
+ Ingress traffic on port 0 is now restricted to the defined flow rules
+ testpmd>
-ethertype_filter
-~~~~~~~~~~~~~~~~~~~~
+Disabling isolated mode::
-Add or delete a L2 Ethertype filter, which identify packets by their L2 Ethertype mainly assign them to a receive queue.
+ testpmd> flow isolate 0 false
+ Ingress traffic on port 0 is not restricted anymore to the defined flow rules
+ testpmd>
-ethertype_filter (port_id) (add|del) (mac_addr|mac_ignr) (mac_address) ethertype (ether_type) (drop|fwd) queue (queue_id)
+Dumping HW internal information
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The available information parameters are:
+``flow dump`` dumps the hardware's internal representation information of
+all flows. It is bound to ``rte_flow_dev_dump()``::
-* port_id: the port which the Ethertype filter assigned on.
+ flow dump {port_id} {output_file}
-* mac_addr: compare destination mac address.
+If successful, it will show::
-* mac_ignr: ignore destination mac address match.
+ Flow dump finished
-* mac_address: destination mac address to match.
+Otherwise, it will complain error occurred::
-* ether_type: the EtherType value want to match,
- for example 0x0806 for ARP packet. 0x0800 (IPv4) and 0x86DD (IPv6) are invalid.
+ Caught error type [...] ([...]): [...]
-* queue_id : The receive queue associated with this EtherType filter. It is meaningless when deleting or dropping.
+Sample QinQ flow rules
+~~~~~~~~~~~~~~~~~~~~~~
-Example, to add/remove an ethertype filter rule:
+Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
-.. code-block:: console
+ testpmd> port stop 0
+ testpmd> vlan set qinq_strip on 0
- testpmd> ethertype_filter 0 add mac_ignr ethertype 0x0806 fwd queue 3
- testpmd> ethertype_filter 0 del mac_ignr ethertype 0x0806 fwd queue 3
+The above command sets the inner and outer TPID's to 0x8100.
-2tuple_filter
-~~~~~~~~~~~~~~~~~
+To change the TPID's the following commands should be used::
-Add or delete a 2-tuple filter,
-which identify packets by specific protocol and destination TCP/UDP port
-and forwards packets into one of the receive queues.
+ testpmd> vlan set outer tpid 0xa100 0
+ testpmd> vlan set inner tpid 0x9100 0
+ testpmd> port start 0
-2tuple_filter (port_id) (add|del) dst_port (dst_port_value) protocol (protocol_value)
-mask (mask_value) tcp_flags (tcp_flags_value) priority (prio_value) queue (queue_id)

-* mask_value: participates in the match or not by bit for field above, 1b means participate.
+Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
-* tcp_flags_value: TCP control bits. The non-zero value is invalid, when the pro_value is not set to 0x06 (TCP).
+::
-* prio_value: priority of this filter.
+ testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
+ vlan tci is 654 / end actions pf / queue index 0 / end

+Sample PFCP rules
+~~~~~~~~~~~~~~~~~
-For example, to select the first 16 bytes from the offset 4 (bytes) of packet's payload as flexible payload.
+PFCP rules can be created by the following commands(s_field need to be 1
+if seid is set)::
-.. code-block:: console
+ testpmd> flow create 0 ingress pattern eth / ipv4 / pfcp s_field is 0 / end
+ actions queue index 3 / end
+ testpmd> flow create 0 ingress pattern eth / ipv4 / pfcp s_field is 1
+ seid is 1 / end actions queue index 3 / end
+ testpmd> flow create 0 ingress pattern eth / ipv6 / pfcp s_field is 0 / end
+ actions queue index 3 / end
+ testpmd> flow create 0 ingress pattern eth / ipv6 / pfcp s_field is 1
+ seid is 1 / end actions queue index 3 / end
- testpmd> flow_director_flex_payload 0 l4 (4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)
+BPF Functions
+--------------
-get_sym_hash_ena_per_port
-~~~~~~~~~~~~~~~~~~~~~~~~~
+The following sections show functions to load/unload eBPF based filters.
+
+bpf-load
+~~~~~~~~
-Get symmetric hash enable configuration per port.
+Load an eBPF program as a callback for particular RX/TX queue::
-get_sym_hash_ena_per_port (port_id)
+ testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
-For example, to get symmetric hash enable configuration of port 1.
+The available load-flags are:
-.. code-block:: console
+* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
- testpmd> get_sym_hash_ena_per_port 1
+* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
-set_sym_hash_ena_per_port
-~~~~~~~~~~~~~~~~~~~~~~~~~
+* ``-``: none.
-Set symmetric hash enable configuration per port to enable or disable.
+.. note::
-set_sym_hash_ena_per_port (port_id) (enable|disable)
+ You'll need clang v3.7 or above to build bpf program you'd like to load
-For example, to set symmetric hash enable configuration of port 1 to enable.
+For example:
.. code-block:: console
- testpmd> set_sym_hash_ena_per_port 1 enable
+ cd examples/bpf
+ clang -O2 -target bpf -c t1.c
-get_hash_global_config
-~~~~~~~~~~~~~~~~~~~~~~
+Then to load (and JIT compile) t1.o at RX queue 0, port 1:
-Get the global configurations of hash filters.
+.. code-block:: console
-get_hash_global_config (port_id)
+ testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
-For example, to get the global configurations of hash filters of port 1.
+To load (not JITed) t1.o at TX queue 0, port 0:
.. code-block:: console
- testpmd> get_hash_global_config 1
+ testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
-set_hash_global_config
-~~~~~~~~~~~~~~~~~~~~~~
+bpf-unload
+~~~~~~~~~~
-Set the global configurations of hash filters.
+Unload previously loaded eBPF program for particular RX/TX queue::
-set_hash_global_config (port_id) (toeplitz|simple_xor|default)
-(ipv4|ipv4-frag|ipv4-tcp|ipv4-udp|ipv4-sctp|ipv4-other|ipv6|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp|ipv6-other|l2_payload)
-(enable|disable)
+ testpmd> bpf-unload rx|tx (portid) (queueid)
-For example, to enable simple_xor for flow type of ipv6 on port 2.
+For example to unload BPF filter from TX queue 0, port 0:
.. code-block:: console
- testpmd> set_hash_global_config 2 simple_xor ipv6 enable
+ testpmd> bpf-unload tx 0 0
