enable subvlan-proxy-arp vlan

enable subvlan-proxy-arp vlan [vlan-name | all]

Description

Enables the automatic entry of subVLAN information in the proxy ARP table.

Syntax Description


`vlan-name`	Specifies a superVLAN name.
all	Specifies all VLANs.

Default

Enabled.

Usage Guidelines

To facilitate communication between subVLANs, by default, an entry is made in the IP ARP table of the superVLAN that performs a proxy ARP function. This allows clients on one subVLAN to communicate with clients on another subVLAN. In certain circumstances, intra-subVLAN communication may not be desired for isolation reasons.

Note

The isolation option works for normal, dynamic, ARP-based client communication.

Example

The following example enables the automatic entry of subVLAN information in the proxy ARP table of the superVLAN "vsuper":

enable subvlan-proxy-arp vlan vsuper
