LAN

(VLAN

)

■

GVRP is based on IEEE 802.1Q and allows for dynamic configuration
of port-based VLANs. GVRP can help you simplify the management of
VLAN configurations in larger networks. Use the command

bridge port gvrpState

to explicitly enable GVRP on the

participating bridge ports and use the command

bridge gvrpState

to enable the bridge GVRP state for the entire system. The bridge
GVRP state enables you to control GVRP on the system without losing
the per-port GVRP state. By default, the GVRP state for the entire
system is

disabled

and the GVRP state for each bridge port is

disabled

■

The system prompts you for a VLAN interface index number before it
displays the detail information.

■

Either you can use network-based IP VLANs (by supplying Layer 3
address information when you configure a VLAN for IP), or you create
the IP VLAN and then define multiple IP interfaces per VLAN. See
Chapter 16.
