Address Resolution Protocol (ARP)
---------------------------------
ARP
---
To manipulate or display ARP_ table entries, the following commands are implemented.
:abbr:`ARP (Address Resolution Protocol)` is a communication protocol used for
discovering the link layer address, such as a MAC address, associated with a
given internet layer address, typically an IPv4 address. This mapping is a
critical function in the Internet protocol suite. ARP was defined in 1982 by
:rfc:`826` which is Internet Standard STD 37.
In Internet Protocol Version 6 (IPv6) networks, the functionality of ARP is
provided by the Neighbor Discovery Protocol (NDP).
To manipulate or display ARP_ table entries, the following commands are
implemented.
.. option:: set protocols static arp 10.1.1.100 hwaddr 08:00:27:de:23:aa
adding a static arp entry
^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: sh
.. option:: show protocols static arp
set protocols static arp 10.1.1.100 hwaddr 08:00:27:de:23:aa

display arp table entries
^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: sh
show protocols static arp
In operational level, display all known ARP table entries
..
vyos@vyos:~$ show protocols static arp
Address HWtype HWaddress Flags Mask Iface
10.1.1.1 ether 08:00:27:de:23:2e C eth1
10.1.1.100 ether 08:00:27:de:23:aa CM eth1
.. code-block:: sh
.. option:: show protocols static arp interface eth1
show protocols static arp interface eth1
In operational level, display all known ARP table entries on a specific
interface.
