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, set the Flow Director and other tasks.

.. code-block:: console

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

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:

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.

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.
On the other hand, to attach a port created by virtual device, above steps are not needed.

port attach (identifier)

For example, to attach a port whose pci address is 0000:02:00.0.

.. code-block:: console

    testpmd> port attach 0000:02:00.0
    Attaching a new port...
    ... snip ...
    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 eth_pcap0,iface=eth0
    Attaching a new port...
    ... snip ...
    Port 0 is attached. Now total ports is 1
    Done

In this case, identifier is "eth_pcap0,iface=eth0".
This identifier format is the same as "--vdev" format of DPDK applications.

port detach
~~~~~~~~~~~

Detach a specific port.

Before detaching a port, the port should be closed.
Also 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.
On the other hand, to remove a port created by a virtual device, above steps are not needed.

port detach (port_id)

For example, to detach a port 0.

.. code-block:: console

    testpmd> port detach 0

Link Bonding Functions
----------------------

The Link Bonding functions make it possible to dynamically create and
manage link bonding devices from within testpmd interactive prompt.

create bonded device
~~~~~~~~~~~~~~~~~~~~

Create a new bonding device:

create bonded device (mode) (socket)

For example, to create a bonded device in mode 1 on socket 0.

.. code-block:: console

    testpmd> create bonded 1 0
    created new bonded device (port X)

add bonding slave
~~~~~~~~~~~~~~~~~

Adds Ethernet device to a Link Bonding device:

add bonding slave (slave id) (port id)

For example, to add Ethernet device (port 6) to a Link Bonding device (port 10).

.. code-block:: console

    testpmd> add bonding slave 6 10


remove bonding slave
~~~~~~~~~~~~~~~~~~~~

Removes an Ethernet slave device from a Link Bonding device:

remove bonding slave (slave id) (port id)

For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10).

.. code-block:: console

    testpmd> remove bonding slave 6 10

set bonding mode
~~~~~~~~~~~~~~~~

Set the Link Bonding mode of a Link Bonding device:

set bonding mode (value) (port id)

For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3).

.. code-block:: console

    testpmd> set bonding mode 3 10

set bonding primary
~~~~~~~~~~~~~~~~~~~

Set an Ethernet slave device as the primary device on a Link Bonding device:

set bonding primary (slave id) (port id)

For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10).

.. code-block:: console

    testpmd> set bonding primary 6 10

set bonding mac
~~~~~~~~~~~~~~~

.. code-block:: console

    testpmd> set bonding xmit_balance_policy 10 l34


set bonding mon_period
~~~~~~~~~~~~~~~~~~~~~~

Set the link status monitoring polling period in milliseconds for a bonding devicie.

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.

set bonding mon_period (port_id) (value)

For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms

.. code-block:: console

        Primary: [3]

Register Functions
------------------

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
~~~~~~~~

Display the value of a port register:

read reg (port_id) (address)

For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel® 82599 10 GbE Controller:

.. code-block:: console

    testpmd> read reg 0 0xEE00
    port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)

read regfield
~~~~~~~~~~~~~

Display a port register bit field:

read regfield (port_id) (address) (bit_x) (bit_y)

For example, reading the lowest two bits from the register in the example above:

.. code-block:: console

    testpmd> read regfield 0 0xEE00 0 1
    port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)

read regbit
~~~~~~~~~~~

Display a single port register bit:

read regbit (port_id) (address) (bit_x)

For example, reading the lowest bit from the register in the example above:

.. code-block:: console

    testpmd> read regbit 0 0xEE00 0
    port 0 PCI register at offset 0xEE00: bit 0=1

write reg
~~~~~~~~~

Set the value of a port register:

write reg (port_id) (address) (value)

For example, to clear a register:

.. code-block:: console

    testpmd> write reg 0 0xEE00 0x0
    port 0 PCI register at offset 0xEE00: 0x00000000 (0)

write regfield
~~~~~~~~~~~~~~

Set bit field of a port register:

write regfield (port_id) (address) (bit_x) (bit_y) (value)

For example, writing to the register cleared in the example above:

.. code-block:: console

    testpmd> write regfield 0 0xEE00 0 1 2
    port 0 PCI register at offset 0xEE00: 0x00000002 (2)

write regbit
~~~~~~~~~~~~

Set single bit value of a port register:

write regbit (port_id) (address) (bit_x) (value)

For example, to set the high bit in the register from the example above:

        mask 000C priority 3 queue 3

flow_director_filter
~~~~~~~~~~~~~~~~~~~~

The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.

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:

*   Perfect match filters.
    The hardware checks a match between the masked fields of the received packets and the programmed filters.

*   Signature filters.
    The hardware checks a match between a hash-based signature of the masked fields of the received packet.

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.

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.

flow_director_filter (port_id) (add|del|update) flow (ipv4-other|ipv4-frag|ipv6-other|ipv6-frag)
