ARP
|
|
---
|
|
|
|
: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.
|
|
|
|
Add static ARP entry
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. option:: set protocols static arp 10.1.1.100 hwaddr 08:00:27:de:23:aa
|
|
|
|
Display ARP entries
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. option:: show protocols static arp
|
|
|
|
Display all known ARP table entries spanning accross all interfaces
|
|
|
|
.. code-block:: sh
|
|
|
|
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
|
|
|
|
|
|
.. option:: show protocols static arp interface eth1
|
|
|
|
Display all known ARP table entries on a given interface only (`eth1`):
|
|
|
|
.. code-block:: sh
|
|
|
|
vyos@vyos:~$ show protocols static arp interface eth1
|
|
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
