Testpmd Runtime Functions
=========================

Where the testpmd application is started in interactive mode, (``-i|--interactive``),
it displays a prompt that can be used to start and stop forwarding,
configure the application, display statistics (including the extended NIC
statistics aka xstats) , set the Flow Director and other tasks::

   testpmd>

The testpmd prompt has some, limited, readline support.
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
as well as access to the command history via the up-arrow.

There is also support for tab completion.
If you type a partial command and hit ``<TAB>`` you get a list of the available completions:

.. code-block:: console

   testpmd> show port <TAB>

       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap X
       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap all
       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap X
       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap all
       ...


.. note::

   Some examples in this document are too long to fit on one line are are shown wrapped at `"\\"` for display purposes::

      testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
               (pause_time) (send_xon) (port_id)

In the real ``testpmd>`` prompt these commands should be on a single line.

Help Functions
--------------

The testpmd has on-line help for the functions that are available at runtime.
These are divided into sections and can be accessed using help, help section or help all:

.. code-block:: console

   testpmd> help

       help control    : Start and stop forwarding.
       help display    : Displaying port, stats and config information.
       help config     : Configuration information.
       help ports      : Configuring ports.
       help registers  : Reading and setting port registers.
       help filters    : Filters configuration help.
       help all        : All of the above sections.


Command File Functions
----------------------

To facilitate loading large number of commands or to avoid cutting and pasting where not
practical or possible testpmd supports alternative methods for executing commands.

* If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
  will execute all CLI commands contained within the file immediately before
  starting packet forwarding or entering interactive mode.

.. code-block:: console

   ./testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt
   Interactive-mode selected
   CLI commands to be read from /home/ubuntu/flow-create-commands.txt
   Configuring Port 0 (socket 0)
   Port 0: 7C:FE:90:CB:74:CE
   Configuring Port 1 (socket 0)
   Port 1: 7C:FE:90:CB:74:CA
   Checking link statuses...
   Port 0 Link Up - speed 10000 Mbps - full-duplex
   Port 1 Link Up - speed 10000 Mbps - full-duplex
   Done
   Flow rule #0 created
   Flow rule #1 created
   ...
   ...
   Flow rule #498 created
   Flow rule #499 created
   Read all CLI commands from /home/ubuntu/flow-create-commands.txt
   testpmd>


* At run-time additional commands can be loaded in bulk by invoking the ``load FILENAME``
  command.

.. code-block:: console

   testpmd> load /home/ubuntu/flow-create-commands.txt
   Flow rule #0 created
   Flow rule #1 created
   ...
   ...
   Flow rule #498 created
   Flow rule #499 created
   Read all CLI commands from /home/ubuntu/flow-create-commands.txt
   testpmd>


In all cases output from any included command will be displayed as standard output.
Execution will continue until the end of the file is reached regardless of
whether any errors occur.  The end user must examine the output to determine if
any failures occurred.


Control Functions
-----------------

start
~~~~~

Start packet forwarding with current configuration::

   testpmd> start

start tx_first
~~~~~~~~~~~~~~

Start packet forwarding with current configuration after sending specified number of bursts of packets::

   testpmd> start tx_first (""|burst_num)

The default burst number is 1 when ``burst_num`` not presented.

stop
~~~~

Stop packet forwarding, and display accumulated statistics::

   testpmd> stop

quit
~~~~

Quit to prompt::

   testpmd> quit


Display Functions
-----------------

The functions in the following sections are used to display information about the
testpmd configuration or the NIC status.

show port
~~~~~~~~~

Display information for a given port or all ports::

   testpmd> show port (info|summary|stats|xstats|fdir|stat_qmap|dcb_tc|cap) (port_id|all)

The available information categories are:

* ``info``: General port information such as MAC address.

* ``summary``: Brief port summary such as Device Name, Driver Name etc.

* ``stats``: RX/TX statistics.

* ``xstats``: RX/TX extended NIC statistics.

* ``fdir``: Flow Director information and statistics.

* ``stat_qmap``: Queue statistics mapping.

* ``dcb_tc``: DCB information such as TC mapping.

* ``cap``: Supported offload capabilities.

For example:

.. code-block:: console

   testpmd> show port info 0

   ********************* Infos for port 0 *********************

   MAC address: XX:XX:XX:XX:XX:XX
   Connect to socket: 0
   memory allocation on the socket: 0

Clear the port statistics for a given port or for all ports::

   testpmd> clear port (info|stats|xstats|fdir|stat_qmap) (port_id|all)

For example::

   testpmd> clear port stats all

show (rxq|txq)
~~~~~~~~~~~~~~

Display information for a given port's RX/TX queue::

   testpmd> show (rxq|txq) info (port_id) (queue_id)

show config
~~~~~~~~~~~

Displays the configuration of the application.
The configuration comes from the command-line, the runtime or the application defaults::

   testpmd> show config (rxtx|cores|fwd|txpkts)

The available information categories are:

* ``rxtx``: RX/TX configuration items.

* ``cores``: List of forwarding cores.

* ``fwd``: Packet forwarding configuration.

* ``txpkts``: Packets to TX configuration.

For example:

.. code-block:: console

   testpmd> show config rxtx

   io packet forwarding - CRC stripping disabled - packets/burst=16
   nb forwarding cores=2 - nb forwarding ports=1
   RX queues=1 - RX desc=128 - RX free threshold=0
   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
   TX queues=1 - TX desc=512 - TX free threshold=0
   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
   TX RS bit threshold=0 - TXQ flags=0x0

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 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``.

* ``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 neighbour 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

   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.

set coremask
~~~~~~~~~~~~

Set the forwarding cores hexadecimal mask::

   testpmd> set coremask (mask)

~~~~~~~~~~~

Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::

   testpmd> set txsplit (off|on|rand)

Where:

* ``off`` disable packet copy & split for CSUM mode.

* ``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).

* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.

set corelist
~~~~~~~~~~~~

Set the list of forwarding cores::

   testpmd> set corelist (x[,y]*)

For example, to change the forwarding cores:

Where:

* ``ip|udp|tcp|sctp`` always relate to  the inner layer.

* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
  as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
  supported). See also the ``csum parse-tunnel`` command.

* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
  as a tunnel packet by the forwarding engine (vxlan, vxlan-gpe are
  supported). See also the ``csum parse-tunnel`` command.

.. note::

   Check the NIC Datasheet for hardware limits.

RSS queue region
~~~~~~~~~~~~~~~~

Set RSS queue region span on a port::

   testpmd> set port (port_id) queue-region region_id (value) \
		queue_start_index (value) queue_num (value)

Set flowtype mapping on a RSS queue region on a port::

   testpmd> set port (port_id) queue-region region_id (value) flowtype (value)

where:

* For the flowtype(pctype) of packet,the specific index for each type has
  been defined in file i40e_type.h as enum i40e_filter_pctype.

Set user priority mapping on a RSS queue region on a port::

   testpmd> set port (port_id) queue-region UP (value) region_id (value)

Flush all queue region related configuration on a port::

   testpmd> set port (port_id) queue-region flush (on|off)

where:

* "on"is just an enable function which server for other configuration,
  it is for all configuration about queue region from up layer,
  at first will only keep in DPDK softwarestored 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``.

csum show
~~~~~~~~~

Display tx checksum offload configuration::

   testpmd> csum show (port_id)

tso set
~~~~~~~

Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::

   testpmd> tso set (segsize) (port_id)

.. note::

   Check the NIC datasheet for hardware limits.

tso show
~~~~~~~~

Display the status of TCP Segmentation Offload::

   testpmd> 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
~~~~~~~~~~~~~

Set the maximum GSO segment size (measured in bytes), which includes the
packet header and the packet payload for GSO-enabled ports (global)::

   testpmd> set gso segsz <length>

show port - gso
~~~~~~~~~~~~~~~

Display the status of Generic Segmentation Offload for a given port::

   testpmd> show port <port_id> gso

~~~~~~~~~~~~~~~

Remove a MAC address from a port::

   testpmd> mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX)

   testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off)

set promisc
~~~~~~~~~~~

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> set promisc (port_id|all) (on|off)

set allmulti
~~~~~~~~~~~~

Set the allmulti mode for a port or for all ports::

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.

For example, to re-attach a bonded port which has been previously detached,
the mode and slave parameters must be given.

.. code-block:: console

   testpmd> port attach net_bond_0,mode=0,slave=1
   Attaching a new port...
   EAL: Initializing pmd_bond for net_bond_0
   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
   Port 0 is attached. Now total ports is 1
   Done


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.

.. code-block:: console

   testpmd> port stop 0
   Stopping ports...
   Done
   testpmd> port close 0
   Closing ports...
   Done

   testpmd> port detach 0
   Detaching a port...
   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
   EAL:   PCI memory unmapped at 0x7f83bfa00000
   EAL:   PCI memory unmapped at 0x7f83bfa80000
   Done


For example, to detach a virtual device port 0.

.. code-block:: console

   testpmd> port stop 0
   Stopping ports...
   Done
   testpmd> port close 0
   Closing ports...
   Done

   testpmd> port detach 0
   Detaching a port...
   PMD: Closing pcap ethdev on numa socket 0
   Port 'net_pcap0' is detached. Now total ports is 0
   Done

To remove a pci device completely from the system, first detach the port from testpmd.
Then the device should be moved under kernel management.
Finally the device can be removed using kernel pci hotplug functionality.

For example, to move a pci device under kernel management:

.. code-block:: console

   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0

   ./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=igb_uio

To remove a port created by a virtual device, above steps are not needed.

Filter Functions
----------------

This section details the available filter functions that are available.

Note these functions interface the deprecated legacy filtering framework,
superseded by *rte_flow*. See `Flow rules management`_.

ethertype_filter
~~~~~~~~~~~~~~~~~~~~

Add or delete a L2 Ethertype filter, which identify packets by their L2 Ethertype mainly assign them to a receive queue::

   ethertype_filter (port_id) (add|del) (mac_addr|mac_ignr) (mac_address) \
                    ethertype (ether_type) (drop|fwd) queue (queue_id)

The available information parameters are:

* ``port_id``: The port which the Ethertype filter assigned on.

* ``mac_addr``: Compare destination mac address.

* ``mac_ignr``: Ignore destination mac address match.

* ``mac_address``: Destination mac address to match.

* ``ether_type``: The EtherType value want to match,
  for example 0x0806 for ARP packet. 0x0800 (IPv4) and 0x86DD (IPv6) are invalid.

* ``queue_id``: The receive queue associated with this EtherType filter.
  It is meaningless when deleting or dropping.

Example, to add/remove an ethertype filter rule::

   testpmd> ethertype_filter 0 add mac_ignr 00:11:22:33:44:55 \
                             ethertype 0x0806 fwd queue 3

   testpmd> ethertype_filter 0 del mac_ignr 00:11:22:33:44:55 \
                             ethertype 0x0806 fwd queue 3

2tuple_filter
~~~~~~~~~~~~~~~~~

Add or delete a 2-tuple filter,
which identifies packets by specific protocol and destination TCP/UDP port
and forwards packets into one of the receive queues::

   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)

The available information parameters are:

* ``port_id``: The port which the 2-tuple filter assigned on.

* ``dst_port_value``: Destination port in L4.

* ``protocol_value``: IP L4 protocol.

* ``mask_value``: Participates in the match or not by bit for field above, 1b means participate.

* ``prio_value``: Priority of this filter.

* ``queue_id``: The receive queue associated with this 2-tuple filter.

Example, to add/remove an 2tuple filter rule::

   testpmd> 2tuple_filter 0 add dst_port 32 protocol 0x06 mask 0x03 \
                          tcp_flags 0x02 priority 3 queue 3

   testpmd> 2tuple_filter 0 del dst_port 32 protocol 0x06 mask 0x03 \
                          tcp_flags 0x02 priority 3 queue 3

5tuple_filter
~~~~~~~~~~~~~~~~~

Add or delete 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::

   5tuple_filter (port_id) (add|del) dst_ip (dst_address) src_ip \
                 (src_address) dst_port (dst_port_value) \

                 mask (mask_value) tcp_flags (tcp_flags_value) \
                 priority (prio_value) queue (queue_id)

The available information parameters are:

* ``port_id``: The port which the 5-tuple filter assigned on.

* ``dst_address``: Destination IP address.

* ``dst_port_value``: TCP/UDP destination port.

* ``src_port_value``: TCP/UDP source port.

* ``protocol_value``: L4 protocol.

* ``mask_value``: Participates in the match or not by bit for field above, 1b means participate

* ``tcp_flags_value``: TCP control bits. The non-zero value is invalid, when the protocol_value is not set to 0x06 (TCP).

* ``prio_value``: The priority of this filter.

* ``queue_id``: The receive queue associated with this 5-tuple filter.

Example, to add/remove an 5tuple filter rule::

   testpmd> 5tuple_filter 0 add 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

   testpmd> 5tuple_filter 0 del 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

syn_filter
~~~~~~~~~~

Using the  SYN filter, TCP packets whose *SYN* flag is set can be forwarded to a separate queue::

   syn_filter (port_id) (add|del) priority (high|low) queue (queue_id)

The available information parameters are:

* ``port_id``: The port which the SYN filter assigned on.

* ``high``: This SYN filter has higher priority than other filters.

* ``low``: This SYN filter has lower priority than other filters.

* ``queue_id``: The receive queue associated with this SYN filter

Example::

   testpmd> syn_filter 0 add priority high queue 3

flex_filter
~~~~~~~~~~~

With flex filter, packets can be recognized by any arbitrary pattern within the first 128 bytes of the packet
and routed into one of the receive queues::

   flex_filter (port_id) (add|del) len (len_value) bytes (bytes_value) \
               mask (mask_value) priority (prio_value) queue (queue_id)

The available information parameters are:

* ``port_id``: The port which the Flex filter is assigned on.

* ``len_value``: Filter length in bytes, no greater than 128.

* ``bytes_value``: A string in hexadecimal, means the value the flex filter needs to match.

* ``mask_value``: A string in hexadecimal, bit 1 means corresponding byte participates in the match.

* ``prio_value``: The priority of this filter.

* ``queue_id``: The receive queue associated with this Flex filter.

Example::

   testpmd> flex_filter 0 add len 16 bytes 0x00000000000000000000000008060000 \
                          mask 000C priority 3 queue 3

   testpmd> flex_filter 0 del len 16 bytes 0x00000000000000000000000008060000 \
                          mask 000C priority 3 queue 3


.. _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.

- Optional and repeated parameters are supported (provided they are listed
  in the contextual help).

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.

- Check whether a flow rule can be created::

   flow validate {port_id}
       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
       pattern {item} [/ {item} [...]] / end
       actions {action} [/ {action} [...]] / end

- Create a flow rule::

   flow create {port_id}
       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
       pattern {item} [/ {item} [...]] / end
       actions {action} [/ {action} [...]] / end

- Destroy specific flow rules::

   flow destroy {port_id} rule {rule_id} [...]

- Destroy all flow rules::

   flow flush {port_id}

- Query an existing flow rule::

   flow query {port_id} {rule_id} {action}

- List existing flow rules sorted by priority, filtered by group
  identifiers::

   flow list {port_id} [group {group_id}] [...]

- Restrict ingress traffic to the defined flow rules::

   flow isolate {port_id} {boolean}

Validating flow rules
~~~~~~~~~~~~~~~~~~~~~

``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()``::

   flow validate {port_id}
      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
      pattern {item} [/ {item} [...]] / end
      actions {action} [/ {action} [...]] / end

If successful, it will show::

   Flow rule validated

Otherwise it will show an error message of the form::

   Caught error type [...] ([...]): [...]

This command uses the same parameters as ``flow create``, their format is
described in `Creating flow rules`_.

Check whether redirecting any Ethernet packet received on port 0 to RX queue
index 6 is supported::

   testpmd> flow validate 0 ingress pattern eth / end
      actions queue index 6 / end
   Flow rule validated
   testpmd>

Port 0 does not support TCPv6 rules::

   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
      actions drop / end
   Caught error type 9 (specific pattern item): Invalid argument
   testpmd>

Creating flow rules
~~~~~~~~~~~~~~~~~~~

``flow create`` validates and creates the specified flow rule. It is bound
to ``rte_flow_create()``::

   flow create {port_id}
      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
      pattern {item} [/ {item} [...]] / end
      actions {action} [/ {action} [...]] / end

If successful, it will return a flow rule ID usable with other commands::

   Flow rule #[...] created

Otherwise it will show an error message of the form::

   Caught error type [...] ([...]): [...]

Parameters describe in the following order:

- 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.

These translate directly to *rte_flow* objects provided as-is to the
underlying functions.

The shortest valid definition only comprises mandatory tokens::

   testpmd> flow create 0 pattern end actions end

Note that PMDs may refuse rules that essentially do nothing such as this
one.

**All unspecified object values are automatically initialized to 0.**

Attributes
^^^^^^^^^^

These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
specified before the ``pattern`` token.

- ``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.

Each instance of an attribute specified several times overrides the previous
value as shown below (group 4 is used)::

   testpmd> flow create 0 group 42 group 24 group 4 [...]

Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.

While not specifying a direction is an error, some rules may allow both
simultaneously.

Most rules affect RX therefore contain the ``ingress`` token::

   testpmd> flow create 0 ingress pattern [...]

Matching pattern
^^^^^^^^^^^^^^^^

A matching pattern starts after the ``pattern`` token. It is made of pattern
items and is terminated by a mandatory ``end`` item.

Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
rte_flow_item_type``).

The ``/`` token is used as a separator between pattern items as shown
below::

   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]

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> flow create 0 ingress pattern eth / udp / ipv4 / end [...]

More information on these restrictions can be found in the *rte_flow*
documentation.

Several items support additional specification structures, for example
``ipv4`` allows specifying source and destination addresses as follows::

   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
      dst is 10.2.0.0 / end [...]

This rule matches all IPv4 traffic with the specified properties.

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.

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:

- ``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.

These yield identical results::

   ipv4 src is 10.1.1.1

::

   ipv4 src spec 10.1.1.1 src mask 255.255.255.255

::

   ipv4 src spec 10.1.1.1 src prefix 32

::

   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value

::

   ipv4 src is 10.1.1.1 src last 0 # 0 disables range

Inclusive ranges can be defined with ``last``::

   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4

Note that ``mask`` affects both ``spec`` and ``last``::

   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

Properties can be modified multiple times::

   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4

::

   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

Actions list
^^^^^^^^^^^^

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.

Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
rte_flow_action_type``).

Dropping all incoming UDPv4 packets can be expressed as follows::

   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
      actions drop / end

Several actions have configurable properties which must be specified when
there is no valid default value. For example, ``queue`` requires a target
queue index.

This rule redirects incoming UDPv4 traffic to queue index 6::

   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
      actions queue index 6 / end

While this one could be rejected by PMDs (unspecified queue index)::

   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
      actions queue / end

As defined by *rte_flow*, the list is not ordered, all actions of a given
rule are performed simultaneously. These are equivalent::

   queue index 6 / void / mark id 42 / end

::

   void / mark id 42 / queue index 6 / end

All actions in a list should have different types, otherwise only the last
action of a given type is taken into account::

   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6

::

   drop / drop / drop / end # drop is performed only once

::

   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24

Considering they are performed simultaneously, opposite and overlapping
actions can sometimes be combined when the end result is unambiguous::

   drop / queue index 6 / end # drop has no effect

::

   queue index 6 / rss queues 6 7 8 / end # queue has no effect

::

   drop / passthru / end # drop has no effect

Note that PMDs may still refuse such combinations.

Destroying flow rules
~~~~~~~~~~~~~~~~~~~~~

``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::

   flow destroy {port_id} rule {rule_id} [...]

If successful, it will show::

   Flow rule #[...] destroyed

It does not report anything for rule IDs that do not exist. The usual error
message is shown when a rule cannot be destroyed::

   Caught error type [...] ([...]): [...]

``flow flush`` destroys all rules on a device and does not take extra
arguments. It is bound to ``rte_flow_flush()``::

   flow flush {port_id}

Any errors are reported as above.

Creating several rules and destroying them::

   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 destroy 0 rule 0 rule 1
   Flow rule #1 destroyed
   Flow rule #0 destroyed
   testpmd>

The same result can be achieved using ``flow flush``::

   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>

Non-existent rule IDs are ignored::

   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 destroy 0 rule 42 rule 10 rule 2
   testpmd>
   testpmd> flow destroy 0 rule 0
   Flow rule #0 destroyed
   testpmd>

Querying flow rules
~~~~~~~~~~~~~~~~~~~

``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()``::

   flow query {port_id} {rule_id} {action}

If successful, it will display either the retrieved data for known actions
or the following message::

   Cannot display result for action type [...] ([...])

Otherwise, it will complain either that the rule does not exist or that some
error occurred::

   Flow rule #[...] not found

::

   Caught error type [...] ([...]): [...]

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::

   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

Querying counters for TCPv6 packets redirected to queue 6::

   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>

Listing flow rules
~~~~~~~~~~~~~~~~~~

``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> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
      actions rss queues 6 7 8 end / end
   Flow rule #2 created
   testpmd> flow list 0
   ID      Group   Prio    Attr    Rule
   0       0       0       i-      ETH IPV4 => QUEUE
   1       0       0       i-      ETH IPV6 => QUEUE
   2       0       5       i-      ETH IPV4 UDP => RSS
   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
   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
   1       24      0       i-      ETH IPV4 UDP => QUEUE
   4       24      10      i-      ETH IPV4 TCP => DROP
   3       24      20      i-      ETH IPV4 => DROP
   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
~~~~~~~~~~~~~~~~~~~~~~

``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()``::

 flow isolate {port_id} {boolean}

If successful, enabling or disabling isolated mode shows either::

 Ingress traffic on port [...]
    is now restricted to the defined flow rules

Or::

 Ingress traffic on port [...]
    is not restricted anymore to the defined flow rules

Otherwise, in case of error::

   Caught error type [...] ([...]): [...]

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).

Enabling isolated mode::

 testpmd> flow isolate 0 true
 Ingress traffic on port 0 is now restricted to the defined flow rules
 testpmd>

Disabling isolated mode::

 testpmd> flow isolate 0 false
 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
 testpmd>

Sample QinQ flow rules
~~~~~~~~~~~~~~~~~~~~~~

Before creating QinQ rule(s) the following commands should be issued to enable QinQ::

   testpmd> port stop 0
   testpmd> vlan set qinq on 0

The above command sets the inner and outer TPID's to 0x8100.

To change the TPID's the following commands should be used::

   testpmd> vlan set outer tpid 0xa100 0
   testpmd> vlan set inner tpid 0x9100 0
   testpmd> port start 0

Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.

::

   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

   testpmd> flow list 0
   ID      Group   Prio    Attr    Rule
   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE

Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.

::

   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
        vlan tci is 654 / end actions pf / queue index 0 / end
   Flow rule #1 validated

   testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
        vlan tci is 654 / end actions pf / queue index 1 / end
   Flow rule #1 created

   testpmd> flow list 0
   ID      Group   Prio    Attr    Rule
   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
   1       0       0       i-      ETH VLAN VLAN=>PF QUEUE

Sample VXLAN encapsulation rule
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

VXLAN encapsulation outer layer has default value pre-configured in testpmd
source code, those can be changed by using the following commands

BPF Functions
--------------

The following sections show functions to load/unload eBPF based filters.

bpf-load
~~~~~~~~

Load an eBPF program as a callback for partciular RX/TX queue::

   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)

The available load-flags are:

* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.

* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.

* ``-``: none.

.. note::

   You'll need clang v3.7 or above to build bpf program you'd like to load

For example:

.. code-block:: console

   cd test/bpf
   clang -O2 -target bpf -c t1.c

Then to load (and JIT compile) t1.o at RX queue 0, port 1::

.. code-block:: console

   testpmd> bpf-load rx 1 0 J ./dpdk.org/test/bpf/t1.o

To load (not JITed) t1.o at TX queue 0, port 0::

.. code-block:: console

   testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o

bpf-unload
~~~~~~~~~~

Unload previously loaded eBPF program for partciular RX/TX queue::

   testpmd> bpf-unload rx|tx (portid) (queueid)

For example to unload BPF filter from TX queue 0, port 0:

.. code-block:: console

   testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
