NETGEAR 8800 Chassis Switch CLI Manual Default Disabled. Usage Guidelines If no optional argument is specified, all the IP interfaces are affected. Example The following command disables IRDP on VLAN accounting: disable irdp vlan accounting disable subvlan-proxy-arp vlan disable subvlan-proxy-arp vlan [ | all] Description Disables the automatic entry of subVLAN information in the proxy ARP table. Syntax Description vlan-name all Specifies a superVLAN name. 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 command disables the automatic entry of subVLAN information in the proxy ARP table of the superVLAN vsuper: disable subvlan-proxy-arp vlan vsuper 858 | Chapter 19.
