+# ARP
+
+The {abbr}`ARP (Address Resolution Protocol)` resolves IPv4 network layer addresses
+to link layer MAC addresses.
+addresses. This mapping is essential for communication within the Internet
+Protocol suite. ARP was standardized in 1982 by {rfc}`826` (STD 37).
+
+:::{note}
+In Internet Protocol version 6 (IPv6) networks, address resolution is
+performed by the Neighbor Discovery Protocol (NDP).
+:::
+
+Use the following commands to configure or view ARP table entries.
+
+## Configuration
+
+```{eval-rst}
+.. cfgcmd:: set protocols static arp interface <interface> address <host> mac <mac>
+
+   **Configure a static ARP entry on the specified interface.**
+
+   This creates a permanent mapping between an IP address and a MAC address
+   on the specified interface.
+
+   Example:
+
+   .. code-block:: none
+
+      set protocols static arp interface eth0 address 192.0.2.1 mac 01:23:45:67:89:01
+```
+
+## Operation
+
+```{eval-rst}
+.. opcmd:: show protocols static arp
+
+   Show all ARP table entries across all interfaces.
+
+   .. code-block:: none
+
+      vyos@vyos:~$ show protocols static arp
+      Address                  HWtype  HWaddress           Flags Mask     Iface
+      10.1.1.1                 ether   00:53:00:de:23:2e   C              eth1
+      10.1.1.100               ether   00:53:00:de:23:aa   CM             eth1
+```
+
+```{eval-rst}
+.. opcmd:: show protocols static arp interface <interface>
+
+   Show all ARP table entries for the specific interface.
+
+   Example for ``eth1``:
+
+   .. code-block:: none
+
+      vyos@vyos:~$ show protocols static arp interface eth1
+      Address                  HWtype  HWaddress           Flags Mask     Iface
+      10.1.1.1                 ether   00:53:00:de:23:2e   C              eth1
+      10.1.1.100               ether   00:53:00:de:23:aa   CM             eth1
