Enables the automatic entry of subVLAN information in the proxy ARP table.
| vlan-name | Specifies a superVLAN name. |
| all | Specifies all VLANs. |
Enabled.
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.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
