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
