no ip proxy-arp
Parameters
None.
Defaults

Usage
This variation of the ARP protocol allows the router to send an ARP response on behalf of an end
node to the requesting host. Proxy ARP can be used to resolve routing issues on end stations that
are unable to route in the subnetted environment. TheSecureStack C2 will answer to ARP requests
on behalf of targeted end stations on neighboring networks. It is disabled by default.
Example
This example shows how to enable proxy ARP on VLAN 1:
C2(su)->router(Config)#interface vlan 1
C2(su)->router(Config-if(Vlan 1))#ip proxy-arp
arp timeout
Use this command to set the duration (in seconds) for dynamically learned entries to remain in the
ARP table before expiring. The no form of this command restores the default value of 14,400
seconds.
