+ 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 behaviour 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-peer-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 IMCP 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``.
+
+Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``.

+
+If enabled, the csum forward engine will try to recognize supported

+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 parameter`` relates to the outer headers (here ``ipv4_out``).

+Enable or disable GRO in ``csum`` forwarding engine::
-set fwd (io|mac|mac_retry|macswap|flowgen|rxonly|txonly|csum|icmpecho)
+ testpmd> set port <port_id> gro on|off
-The available information categories are:
+If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
+packets received from the given port.
-* 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.
+If disabled, packets received from the given port won't be performed
+GRO. By default, GRO is disabled for all ports.
-* mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
+.. note::
-* mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
+ 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.
-* macswap: MAC swap forwarding mode.
- Swaps the source and the destination Ethernet addresses of packets before forwarding them.
+show port - gro
+~~~~~~~~~~~~~~~
-* flowgen: multi-flow generation mode.
- Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
+Display GRO configuration for a given port::
-* rxonly: receives packets but doesn't transmit them.
+ testpmd> show port <port_id> gro
-* txonly: generates and transmits packets without receiving any.
+set gro flush
+~~~~~~~~~~~~~
-* csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
+Set the cycle to flush the GROed packets from reassembly tables::
-* icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
+ 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.
-Example:
+The ``cycles`` is measured in GRO operation times. The csum forwarding
+engine flushes the GROed packets from the tables every ``cycles`` GRO
+operations.
-.. code-block:: console
+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>

+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...

+
+In this case, identifier is ``net_pcap0``.
+This identifier format is the same as ``--vdev`` format of DPDK applications.
+

+
+
+port detach
+~~~~~~~~~~~
+
+Detach a specific port::
+
+ testpmd> port detach (port_id)
+
+Before detaching a port, the port should be stopped and closed.
+
+For example, to detach a pci device port 0.
+

-port stop
-~~~~~~~~~
-Stop all ports or a specific port:
+.. _testpmd_flow_director:
-port stop (port_id|all)
+flow_director_filter
+~~~~~~~~~~~~~~~~~~~~
-port close
-~~~~~~~~~~
+The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
-Close all ports or a specific port:
+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:
-port close (port_id|all)
+* 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.
-port start/stop queue
-~~~~~~~~~~~~~~~~~~~~~
+* Signature filters.
+ The hardware checks a match between a hash-based signature of the masked fields of the received packet.
-Start/stop a rx/tx queue on a specific port:
+* 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.
-port (port_id) (rxq|txq) (queue_id) (start|stop)
+* 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.
-Only take effect when port is started.
+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.
-port config - speed
-~~~~~~~~~~~~~~~~~~~
+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.
-Set the speed and duplex mode for all ports or a specific port:
+Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
-port config (port_id|all) speed (10|100|1000|10000|auto) duplex (half|full|auto)

-Link Bonding Functions
-----------------------
+For example to set GRE key length for input set to 4 bytes on port 0::
-The Link Bonding functions make it possible to dynamically create and
-manage link bonding devices from within testpmd interactive prompt.
+ testpmd> global_config 0 gre-key-len 4
-create bonded device
-~~~~~~~~~~~~~~~~~~~~
-Create a new bonding device:
+.. _testpmd_rte_flow:
-create bonded device (mode) (socket)
+Flow rules management
+---------------------
-For example, to create a bonded device in mode 1 on socket 0.
+Control of the generic flow API (*rte_flow*) is fully exposed through the
+``flow`` command (validation, creation, destruction, queries and operation
+modes).
-.. code-block:: console
+Considering *rte_flow* overlaps with all `Filter Functions`_, using both
+features simultaneously may cause undefined side-effects and is therefore
+not recommended.
- testpmd> create bonded 1 0
- created new bonded device (port X)
+``flow`` syntax
+~~~~~~~~~~~~~~~
-add bonding slave
-~~~~~~~~~~~~~~~~~
+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:
-Adds Ethernet device to a Link Bonding device:
+- Pressing *?* or the *<tab>* key displays contextual help for the current
+ token, not that of the entire command.
-add bonding slave (slave id) (port id)
+- Optional and repeated parameters are supported (provided they are listed
+ in the contextual help).
-For example, to add Ethernet device (port 6) to a Link Bonding device (port 10).
+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.
-.. code-block:: console
+- Check whether a flow rule can be created::
- testpmd> add bonding slave 6 10
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
+- Create a flow rule::
-remove bonding slave
-~~~~~~~~~~~~~~~~~~~~
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-Removes an Ethernet slave device from a Link Bonding device:
+- Destroy specific flow rules::
-remove bonding slave (slave id) (port id)
+ flow destroy {port_id} rule {rule_id} [...]
-For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10).
+- Destroy all flow rules::
-.. code-block:: console
+ flow flush {port_id}
- testpmd> remove bonding slave 6 10
+- Query an existing flow rule::
-set bonding mode
-~~~~~~~~~~~~~~~~
+ flow query {port_id} {rule_id} {action}
-Set the Link Bonding mode of a Link Bonding device:
+- List existing flow rules sorted by priority, filtered by group
+ identifiers::
-set bonding mode (value) (port id)
+ flow list {port_id} [group {group_id}] [...]
-For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3).
+- Restrict ingress traffic to the defined flow rules::
-.. code-block:: console
+ flow isolate {port_id} {boolean}
- testpmd> set bonding mode 3 10
+Validating flow rules
+~~~~~~~~~~~~~~~~~~~~~
-set bonding primary
-~~~~~~~~~~~~~~~~~~~
+``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()``::
-Set an Ethernet slave device as the primary device on a Link Bonding device:
+ flow validate {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-set bonding primary (slave id) (port id)
+If successful, it will show::
-For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10).
+ Flow rule validated
-.. code-block:: console
+Otherwise it will show an error message of the form::
- testpmd> set bonding primary 6 10
+ Caught error type [...] ([...]): [...]
-set bonding mac
-~~~~~~~~~~~~~~~
+This command uses the same parameters as ``flow create``, their format is
+described in `Creating flow rules`_.
-Set the MAC address of a Link Bonding device:
+Check whether redirecting any Ethernet packet received on port 0 to RX queue
+index 6 is supported::
-set bonding mac (port id) (mac)
+ testpmd> flow validate 0 ingress pattern eth / end
+ actions queue index 6 / end
+ Flow rule validated
+ testpmd>
-For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01
+Port 0 does not support TCPv6 rules::
-.. code-block:: console
+ testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
+ actions drop / end
+ Caught error type 9 (specific pattern item): Invalid argument
+ testpmd>
- testpmd> set bonding mac 10 00:00:00:00:00:01
+Creating flow rules
+~~~~~~~~~~~~~~~~~~~
-set bonding xmit_balance_policy
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+``flow create`` validates and creates the specified flow rule. It is bound
+to ``rte_flow_create()``::
-Set the transmission policy for a Link Bonding device when it is in Balance XOR mode:
+ flow create {port_id}
+ [group {group_id}] [priority {level}] [ingress] [egress]
+ pattern {item} [/ {item} [...]] / end
+ actions {action} [/ {action} [...]] / end
-set bonding xmit_balance_policy (port_id) (l2|l23|l34)
+If successful, it will return a flow rule ID usable with other commands::
-For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports )
+ Flow rule #[...] created
-.. code-block:: console
+Otherwise it will show an error message of the form::
- testpmd> set bonding xmit_balance_policy 10 l34
+ Caught error type [...] ([...]): [...]
+Parameters describe in the following order:
-set bonding mon_period
-~~~~~~~~~~~~~~~~~~~~~~
+- Attributes (*group*, *priority*, *ingress*, *egress* 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.
-Set the link status monitoring polling period in milliseconds for a bonding devicie.
+These translate directly to *rte_flow* objects provided as-is to the
+underlying functions.
-This adds support for PMD slave devices which do not support link status interrupts.
-When the mon_period is set to a value greater than 0 then all PMD's which do not support
-link status ISR will be queried every polling interval to check if their link status has changed.
+The shortest valid definition only comprises mandatory tokens::
-set bonding mon_period (port_id) (value)
+ testpmd> flow create 0 pattern end actions end
-For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms
+Note that PMDs may refuse rules that essentially do nothing such as this
+one.
-.. code-block:: console
+**All unspecified object values are automatically initialized to 0.**
- testpmd> set bonding mon_period 5 150
+Attributes
+^^^^^^^^^^
+These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
+specified before the ``pattern`` token.
-show bonding config
-~~~~~~~~~~~~~~~~~~~
+- ``group {group id}``: priority group.
+- ``priority {level}``: priority level within group.
+- ``ingress``: rule applies to ingress traffic.
+- ``egress``: rule applies to egress traffic.
-Show the current configuration of a Link Bonding device:
+Each instance of an attribute specified several times overrides the previous
+value as shown below (group 4 is used)::
-show bonding config (port id)
+ testpmd> flow create 0 group 42 group 24 group 4 [...]
-For example,
-to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
-in balance mode with a transmission policy of layer 2+3.
+Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
-.. code-block:: console
+While not specifying a direction is an error, some rules may allow both
+simultaneously.
- testpmd> show bonding config 9
- Bonding mode: 2
- Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
- Slaves (3): [1 3 4]
- Active Slaves (3): [1 3 4]
- Primary: [3]
+Most rules affect RX therefore contain the ``ingress`` token::
-Register Functions
-------------------
+ testpmd> flow create 0 ingress pattern [...]
-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.

+^^^^^^^^^^^^^^^^
-read reg
-~~~~~~~~
+A matching pattern starts after the ``pattern`` token. It is made of pattern
+items and is terminated by a mandatory ``end`` item.
-Display the value of a port register:
+Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
+rte_flow_item_type``).
-read reg (port_id) (address)
+The ``/`` token is used as a separator between pattern items as shown
+below::
-For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
-.. code-block:: console
+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::
- testpmd> read reg 0 0xEE00
- port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
+ testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
-read regfield
-~~~~~~~~~~~~~
+More information on these restrictions can be found in the *rte_flow*
+documentation.
-Display a port register bit field:
+Several items support additional specification structures, for example
+``ipv4`` allows specifying source and destination addresses as follows::
-read regfield (port_id) (address) (bit_x) (bit_y)
+ testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
+ dst is 10.2.0.0 / end [...]
-For example, reading the lowest two bits from the register in the example above:
+This rule matches all IPv4 traffic with the specified properties.
-.. code-block:: console
+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.
- testpmd> read regfield 0 0xEE00 0 1
- port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)
+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:
-read regbit
-~~~~~~~~~~~
+- ``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 from a prefix length.
-Display a single port register bit:
+These yield identical results::
-read regbit (port_id) (address) (bit_x)
+ ipv4 src is 10.1.1.1
-For example, reading the lowest bit from the register in the example above:
+::
-.. code-block:: console
+ ipv4 src spec 10.1.1.1 src mask 255.255.255.255
- testpmd> read regbit 0 0xEE00 0
- port 0 PCI register at offset 0xEE00: bit 0=1
+::
-write reg
-~~~~~~~~~
+ ipv4 src spec 10.1.1.1 src prefix 32
-Set the value of a port register:
+::
-write reg (port_id) (address) (value)
+ ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
-For example, to clear a register:
+::
-.. code-block:: console
+ ipv4 src is 10.1.1.1 src last 0 # 0 disables range
- testpmd> write reg 0 0xEE00 0x0
- port 0 PCI register at offset 0xEE00: 0x00000000 (0)
+Inclusive ranges can be defined with ``last``::
-write regfield
-~~~~~~~~~~~~~~
+ ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
-Set bit field of a port register:
+Note that ``mask`` affects both ``spec`` and ``last``::
-write regfield (port_id) (address) (bit_x) (bit_y) (value)
+ 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
-For example, writing to the register cleared in the example above:
+Properties can be modified multiple times::
-.. code-block:: console
+ ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
- testpmd> write regfield 0 0xEE00 0 1 2
- port 0 PCI register at offset 0xEE00: 0x00000002 (2)
+::
-write regbit
-~~~~~~~~~~~~
+ ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
-Set single bit value of a port register:
+Pattern items
+^^^^^^^^^^^^^
-write regbit (port_id) (address) (bit_x) (value)
+This section lists supported pattern items and their attributes, if any.
-For example, to set the high bit in the register from the example above:
+- ``end``: end list of pattern items.
-.. code-block:: console
+- ``void``: no-op pattern item.
- testpmd> write regbit 0 0xEE00 31 1

+Actions list
+^^^^^^^^^^^^
- filter[0]:
- Destination Port: 0x0020 mask: 1
- protocol: 0x06 mask:1 tcp_flags: 0x02
- priority: 3 queue: 3
+A list of actions starts after the ``actions`` token in the same fashion as
+`Matching pattern`_; actions are separated by ``/`` tokens and the list is
+terminated by a mandatory ``end`` action.
-add_5tuple_filter
-~~~~~~~~~~~~~~~~~
+Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
+rte_flow_action_type``).
-Add a 5-tuple filter,
-which consists of a 5-tuple (protocol, source and destination IP addresses, source and destination TCP/UDP/SCTP port)
-and routes packets into one of the receive queues.
+Dropping all incoming UDPv4 packets can be expressed as follows::
-add_5tuple_filter (port_id) dst_ip (dst_address) src_ip (src_address) dst_port (dst_port_value) src_port (src_port_value)
-protocol (protocol_value) mask (mask_value) flags (flags_value) priority (prio_value) queue (queue_id) index (idx)
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions drop / end
-The available information parameters are:
+Several actions have configurable properties which must be specified when
+there is no valid default value. For example, ``queue`` requires a target
+queue index.
-* port_id: the port which the 5-tuple filter assigned on.
+This rule redirects incoming UDPv4 traffic to queue index 6::
-* dst_address: destination IP address.
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions queue index 6 / end
-* src_address: source IP address.
+While this one could be rejected by PMDs (unspecified queue index)::
-* dst_port_value: TCP/UDP destination port.
+ testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
+ actions queue / end
-* src_port_value: TCP/UDP source port.
+As defined by *rte_flow*, the list is not ordered, all actions of a given
+rule are performed simultaneously. These are equivalent::
-* protocol_value: L4 protocol.
+ queue index 6 / void / mark id 42 / end
-* mask_value: participates in the match or not by bit for field above, 1b means participate
+::
-* flags_value: TCP control bits. The non-zero value is invalid, when the protocol_value is not set to 0x06 (TCP).
+ void / mark id 42 / queue index 6 / end
-* prio_value: the priority of this filter.
+All actions in a list should have different types, otherwise only the last
+action of a given type is taken into account::
-* queue_id: The receive queue associated with this 5-tuple filter.
+ queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
-* index: the index of this 5-tuple filter
+::
-Example:
+ drop / drop / drop / end # drop is performed only once
-.. code-block:: console
+::
- testpmd> add_5tuple_filter 1 dst_ip 2.2.2.5 src_ip 2.2.2.4 dst_port 64 src_port 32 protocol 0x06 mask 0x1F flags 0x0 priority 3 queue 3 index 0
+ mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
-remove_5tuple_filter
-~~~~~~~~~~~~~~~~~~~~
+Considering they are performed simultaneously, opposite and overlapping
+actions can sometimes be combined when the end result is unambiguous::
-Remove a 5-tuple filter
+ drop / queue index 6 / end # drop has no effect
-remove_5tuple_filter (port_id) index (idx)
+::
-get_5tuple_filter
-~~~~~~~~~~~~~~~~~
+ drop / dup index 6 / end # same as above
-Get and display a 5-tuple filter
+::
-get_5tuple_filter (port_id) index (idx)
+ queue index 6 / rss queues 6 7 8 / end # queue has no effect
-Example:
+::
-.. code-block:: console
+ drop / passthru / end # drop has no effect
- testpmd> get_5tuple_filter 1 index 0
+Note that PMDs may still refuse such combinations.

+Actions
+^^^^^^^
-add_syn_filter
-~~~~~~~~~~~~~~
+This section lists supported actions and their attributes, if any.
-Add SYN filter, which can forward TCP packets whose *SYN* flag is set into a separate queue.
+- ``end``: end list of actions.
-add_syn_filter (port_id) priority (high|low) queue (queue_id)
+- ``void``: no-op action.
-The available information parameters are:
+- ``passthru``: let subsequent rule process matched packets.
-* port_id: the port which the SYN filter assigned on.
+- ``mark``: attach 32 bit value to packets.
-* high: this SYN filter has higher priority than other filters.
+ - ``id {unsigned}``: 32 bit value to return with packets.
-* low: this SYN filter has lower priority than other filters.
+- ``flag``: flag packets.
-* queue_id: The receive queue associated with this SYN filter
+- ``queue``: assign packets to a given queue index.
-Example:

+- ``vf``: redirect packets to virtual device function.
-Example:
+ - ``original {boolean}``: use original VF ID if possible.
+ - ``id {unsigned}``: VF ID to redirect packets to.
-.. code-block:: console
+Destroying flow rules
+~~~~~~~~~~~~~~~~~~~~~
- testpmd> get_syn_filter 0
+``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::
- syn filter: on, priority: high, queue: 3
+ flow destroy {port_id} rule {rule_id} [...]
-flex_filter
-~~~~~~~~~~~
+If successful, it will show::
-With flex filter, packets can be recognized by any arbitrary pattern within the first 128 bytes of the packet
-and routes packets into one of the receive queues.
+ Flow rule #[...] destroyed
-flex_filter (port_id) (add|del) len (len_value) bytes (bytes_value)
-mask (mask_value) priority (prio_value) queue (queue_id)
+It does not report anything for rule IDs that do not exist. The usual error
+message is shown when a rule cannot be destroyed::
-The available information parameters are:
+ Caught error type [...] ([...]): [...]
-* port_id: the port which the Flex filter is assigned on.
+``flow flush`` destroys all rules on a device and does not take extra
+arguments. It is bound to ``rte_flow_flush()``::
-* len_value: filter length in bytes, no greater than 128.
+ flow flush {port_id}
-* bytes_value: a string in hexadecimal, means the value the flex filter needs to match.
+Any errors are reported as above.
-* mask_value: a string in hexadecimal, bit 1 means corresponding byte participates in the match.
+Creating several rules and destroying them::
-* prio_value: the priority of this filter.
+ testpmd> flow create 0 ingress pattern eth / ipv6 / end

+Querying flow rules
+~~~~~~~~~~~~~~~~~~~
-flow_director_filter
-~~~~~~~~~~~~~~~~~~~~
+``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()``::
-The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
+ flow query {port_id} {rule_id} {action}
-Two types of filtering are supported which are referred to as Perfect Match and Signature filters, the match mode
-is set by the --pkt-filter-mode command-line parameter:
+If successful, it will display either the retrieved data for known actions
+or the following message::
-* Perfect match filters.
- The hardware checks a match between the masked fields of the received packets and the programmed filters.
+ Cannot display result for action type [...] ([...])
-* Signature filters.
- The hardware checks a match between a hash-based signature of the masked fields of the received packet.
+Otherwise, it will complain either that the rule does not exist or that some
+error occurred::
-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.
+ Flow rule #[...] not found
-Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
+::
-# Commands to add flow director filters of different flow types.

-src (src_ip_address) dst (dst_ip_address) vlan (vlan_value) flexbytes (flexbytes_value)
-(drop|fwd) queue (queue_id) fd_id (fd_id_value)
+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::
-flow_director_filter (port_id) (add|del|update) flow (udp4|tcp4|udp6|tcp6)
-src (src_ip_address) (src_port) dst (dst_ip_address) (dst_port) vlan (vlan_value)

-vlan (vlan_value) flexbytes (flexbytes_value) (drop|fwd) queue (queue_id) fd_id (fd_id_value)
+Querying counters for TCPv6 packets redirected to queue 6::
-For example, to add an udp flow type filter:
+ 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

+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> flow_director_filter 0 add flow ip4 src 2.2.2.3 dst 2.2.2.5 vlan 0x1 flexbytes (0x88,0x48) fwd queue 1 fd_id 1
+If successful, enabling or disabling isolated mode shows either::
-flush_flow_director
-~~~~~~~~~~~~~~~~~~~
+ Ingress traffic on port [...]
+ is now restricted to the defined flow rules
-flush all flow director filters on a device:
+Or::
-flush_flow_director (port_id)
+ Ingress traffic on port [...]
+ is not restricted anymore to the defined flow rules
-Example, to flush all flow director filter on port 0:
+Otherwise, in case of error::
-.. code-block:: console
+ Caught error type [...] ([...]): [...]
- testpmd> flush_flow_director 0
+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).
-flow_director_mask
-~~~~~~~~~~~~~~~~~~
+Enabling isolated mode::
-set flow director's masks on match input set
+ testpmd> flow isolate 0 true
+ Ingress traffic on port 0 is now restricted to the defined flow rules
+ testpmd>
-flow_director_mask (port_id) vlan (vlan_value) src_mask (ipv4_src) (ipv6_src) (src_port) dst_mask (ipv4_dst) (ipv6_dst) (dst_port)
+Disabling isolated mode::
-Example, to set flow director mask on port 0:
+ testpmd> flow isolate 0 false
+ Ingress traffic on port 0 is not restricted anymore to the defined flow rules
+ testpmd>
-.. code-block:: console
+Sample QinQ flow rules
+~~~~~~~~~~~~~~~~~~~~~~
- testpmd> flow_director_mask 0 vlan 0xefff src_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF dst_mask 255.255.255.255 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF
+Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
+ testpmd> port stop 0
+ testpmd> vlan set qinq on 0
-flow_director_flex_mask
-~~~~~~~~~~~~~~~~~~~~~~~
+The above command sets the inner and outer TPID's to 0x8100.
-set masks of flow director's flexible payload based on certain flow type:
+To change the TPID's the following commands should be used::
-flow_director_flex_mask (port_id) flow (raw|ip4|ip4-frag|tcp4|udp4|sctp4|ip6|ip6-frag|tcp6|udp6|sctp6|all) (mask)
+ testpmd> vlan set outer tpid 0xa100 0
+ testpmd> vlan set inner tpid 0x9100 0
+ testpmd> port start 0
-Example, to set flow director's udpv4 flex mask on port 0:
+Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
-.. code-block:: console
+::
- testpmd> flow_director_flex_mask 0 flow all (0xff,0xff,0,0,0,0,0,0,0,0,0,0,0,0,0,0)
+ testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
+ vlan tci is 456 / end actions vf id 1 / queue index 0 / end
+ Flow rule #0 validated
+ testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
+ vlan tci is 456 / end actions vf id 123 / queue index 0 / end
+ Flow rule #0 created
-flow_director_flex_payload
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+ testpmd> flow list 0
+ ID Group Prio Attr Rule
+ 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
-Configure flexible payload selection.
+Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
-flow_director_flex_payload (port_id) (raw|l2|l3|l4) (config)
