Address Resolution Protocol Commands
This section describes the commands you use to configure Address Resolution Protocol (ARP) and to view ARP
information on the switch. ARP associates IP addresses with MAC addresses and stores the information as ARP
entries in the ARP cache.
arp
This command creates an ARP entry. The value for ipaddress is the IP address of a device on a subnet attached
to an existing routing interface. The parameter
macaddr is a unicast MAC address for that device.
The format of the MAC address is 6 two-digit hexadecimal numbers that are separated by colons, for example
00:06:29:32:81:40.
no arp
This command deletes an ARP entry. The value for arpentry is the IP address of the interface. The value for
ipaddress is the IP address of a device on a subnet attached to an existing routing interface. The parameter
macaddr is a unicast MAC address for that device.
ip proxy-arp
This command enables proxy ARP on a router interface or range of interfaces. Without proxy ARP, a device only
responds to an ARP request if the target IP address is an address configured on the interface where the ARP
request arrived. With proxy ARP, the device may also respond if the target IP address is reachable. The device
only responds if all next hops in its route to the destination are through interfaces other than the interface that
received the ARP request.
