ƒip_addr — IP address or IP alias to map to the specified MAC address.

ƒhw_addr — MAC address to map to the specified IP address or IP alias.

ƒethernet interface-number— Ethernet port number.

ƒvlan vlan-id— VLAN number.

ƒport-channelnumber — Port-channel number.

Default Configuration

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

no arp timeout seconds
