ip proxy-arp

Defaults

None.

Mode

Global configuration: C3(su)‐>router(Config)#

Usage

The IP address specified for the static ARP entry must fall within one of the subnets or networks defined on the routed interfaces of the system ( or stack, if applicable). The system can then match the IP address of the static ARP entry with the appropriate routed interface and associate it with the correct VLAN.

Example

This example shows how to add a permanent ARP entry for the IP address 130.2.3.1 and MAC address 0003.4712.7a99:

C3(su)->router(Config)#arp 130.2.3.1 0003.4712.7a99

ip proxy-arp

Use this command to enable proxy ARP on an interface. The no form of this command disables proxy ARP.

Syntax

ip proxy-arp

no ip proxy-arp

Parameters

None.

Defaults

Disabled.

Mode

Interface configuration: C3(su)‐>router(Config‐if(Vlan 1))#

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. The SecureStack C3 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:

C3(su)->router(Config)#interface vlan 1

C3(su)->router(Config-if(Vlan 1))#ip proxy-arp
