.. _intcommands:
Interface Commands
==================
.. toctree::
.. _showintcommand:
Show Interface
==============
Shows software interface information including counters and features
Summary/Usage
-------------
.. code-block:: shell
show interface [address|addr|features|feat] [<interface> [<interface> [..]]]
Examples
--------
Example of how to show the interface counters:
.. code-block:: console
vpp# show int
Name Idx State Counter Count
TenGigabitEthernet86/0/0 1 up rx packets 6569213
rx bytes 9928352943
tx packets 50384
tx bytes 3329279
TenGigabitEthernet86/0/1 2 down
VirtualEthernet0/0/0 3 up rx packets 50384
rx bytes 3329279
tx packets 6569213
tx bytes 9928352943
drops 1498
local0 0 down
Example of how to display the interface placement:
.. code-block:: console
vpp# show interface rx-placement

Clear Interfaces
================
Clear the statistics for all interfaces (statistics associated with the
'*show interface*' command).
Summary/Usage
-------------
.. code-block:: shell
clear interfaces
Example
-------
Example of how to clear the statistics for all interfaces:
.. code-block:: console
vpp# clear interfaces
Set Interface Mac Address
=========================
The '*set interface mac address* ' command allows to set MAC address of
given interface. In case of NIC interfaces the one has to support MAC
address change. A side effect of MAC address change are changes of MAC
addresses in FIB tables (ipv4 and ipv6).
Summary/Usage
-------------
.. code-block:: shell
set interface mac address <interface> <mac-address>.
Examples
--------
Examples of how to change MAC Address of interface:
.. code-block:: console
vpp# set interface mac address GigabitEthernet0/8/0 aa:bb:cc:dd:ee:01
vpp# set interface mac address host-vpp0 aa:bb:cc:dd:ee:02
vpp# set interface mac address tap-0 aa:bb:cc:dd:ee:03
vpp# set interface mac address pg0 aa:bb:cc:dd:ee:04
Set Interface Mtu
=================
.. toctree::
Summary/Usage
-------------
.. code-block:: shell
set interface mtu [packet|ip4|ip6|mpls] <value> <interface>.
Set Interface Promiscuous
=========================
Summary/Usage
-------------
.. code-block:: shell
set interface promiscuous [on|off] <interface>.
.. _setintstate:
Set Interface State
===================
This command is used to change the admin state (up/down) of an
interface.
If an interface is down, the optional '*punt*' flag can also be set. The
'*punt*' flag implies the interface is disabled for forwarding but punt
all traffic to slow-path. Use the '*enable*' flag to clear '*punt*' flag
(interface is still down).
Summary/Usage
-------------
.. code-block:: shell
set interface state <interface> [up|down|punt|enable].
Examples
--------
Example of how to configure the admin state of an interface to **up**:
.. code-block:: console
vpp# set interface state GigabitEthernet2/0/0 up
Example of how to configure the admin state of an interface to **down**:
.. code-block:: console
vpp# set interface state GigabitEthernet2/0/0 down
