no arp

ip_addr hw_addr {ethernet interface-number | vlan vlan-id | port-channel number | }

User Guidelines

The software uses ARP cache entries to translate 32-bit IP addresses into 48-bit hardware addresses. Because most hosts

support dynamic resolution, static ARP cache entries do not need to be specified.

Example

The following example adds the IP address 198.133.219.232 and MAC address 00-00-0c-40-0f-bc to the ARP table.

Console (config)# arp 198.133.219.232 0000.0c40.0fbc ethernet e8
