Address Resolution Protocol (ARP) Commands
This section describes the commands you use to configure 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. <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.
Format arp <ipaddress> <macaddr>
Mode
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. <macaddr> is a unicast MAC address for that device.
Format no arp <ipaddress> <macaddr>
Mode
ip proxy-arp
This command enables proxy ARP on a router interface. 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.
Default
