Activates a broadcast limit for either all ports in the switch or, if VLANs
are configured, for all ports in the selected VLAN. (You can accept the
default broadcast limit setting, change it, or turn it off.)
Enabling Both IP and IPX (IP_IPX)
Enabling ABC for IP and IPX causes the switch to:
Send a proxy IP ARP reply for hosts whose addresses the switch has
learned.
Send a proxy NSQ (nearest server query) reply for services the switch has
learned.
Enabling for both IP and IPX also allows you to choose whether to:
Enable ABC for IP RIP Control and/or IPX RIP/SAP control, as described
in the preceeding subsections.
Set a broadcast limit for either all ports in the switch or, if VLANs are
configured, for all ports in the selected VLAN.
