add arp
Adds a static ARP (Address Resolution Protocol) entry to the ARP cache on the current Ethernet
interface. Each interface maintains its own ARP cache that can store up to 4,096 entries.
Each ARP entry provides a mapping between a 32-bit IP address and a 48-bit MAC address. The
interface uses this mapping to resolve the IP address or MAC address when provided with only
one or the other. A static ARP entry permanently associates a MAC address with an IP address
until you manually remove the entry from the selected interface using the del arp command.
Mode
interface:ethernet:csi(<c/s/i>)
Syntax
add arp <ip-address> <mac-address>
Arguments
Example
This example adds a static entry to the ARP cache for interface 1/11/1. This configures
interface 1/11/1 to always resolve MAC address 00:50:41:de:8b:29 to IP address 172.31.1.1.
cli:root# interface 1/11/1
mode: interface:ethernet:csi(1/11/1)
cli:interface:ethernet:csi(1/11/1)# add arp 172.31.1.1 00:50:41:de:8b:29
cli:interface:ethernet:csi(1/11/1)# show arp
