GVRP

Port-Based Virtual LANs

(VLANs) and GVRP

Converting a Dynamic VLAN to a Static VLAN. If a port on the switch

has joined a dynamic VLAN, you can use the following command to convert

that dynamic VLAN to a static VLAN:

Syntax: static <dynamic-vlan-id>

For example, to convert dynamic VLAN 333 (from the previous example) to a

static VLAN:

HP4108(config)# static 333

When you convert a dynamic VLAN to a static VLAN, all ports on the switch

are assigned to the VLAN in Auto mode.

To view, enable, disable, or reconfigure GVRP:

1. Click on the Configuration tab.

2. Click on [VLAN Configuration] and do the following:

•To enable or disable GVRP, click on GVRP Enabled.

•To change the Unknown VLAN field for any port:

i. Click on [GVRP Security] and make the desired changes.

ii. Cl ick on [Apply] to save and implement your changes to the

Unknown VLAN fields.

GVRP Operating Notes

■A dynamic VLAN must be converted to a static VLAN before it can have

an IP address.

■The total number of VLANs on the switch (static and dynamic combined)

cannot exceed the current Maximum VLANs setting. For example, in t he

factory default state, the switch supports eight VLANs. Thus, in a case

where four static VLANs are configured on the switch, the switch can

accept up to four additional VLANs in any c ombination of static and

dynamic. Any additional VLANs advertised to the switch will not be added

unless you first increase the Maximum VLANs setting. In the Menu inter-

face, click on 2. Switch Configuration ... | 8. VLAN Menu | 1. VLAN Support. In the

global config level of the CLI, use max-vlans.
