ProSAFE M7100 Managed Switches
Address Resolution Protocol (ARP) Commands
This section describes the commands you use to configure ARP and to view ARP information
about 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 e
xample 00:06:29:32:81:40.
no arp
This command deletes an ARP entry. The value for <arpentry> is the IP addres
s 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.
ip local-proxy-arp
This command enables local-proxy-arp on interface or range of interfaces. The switch only
responds if all next hops in its route to the destination are through interfaces other than the
interface that received the ARP request. Enabling local proxy ARP removes this restriction.
no ip local-proxy-arp
This command disables local-proxy-arp on the interface or a range of interfaces.
