342CHAPTER 14: VIRTUAL LANS (VLANS)

■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.

	and disabled.
Index	System-assigned index number that identifies a VLAN.
	Statistics appear for the VLAN that you specify.
Layer 3 addresses	Information that is used to set up flood domains for
(3500 and 9000 Layer 3) overlapping IP VLAN subnetworks (network-based
	VLANs).
Name	Character string 0 through 32 bytes that identifies the
	VLAN. The default VLAN always uses the name
