VLAN Management
GVRP Set tings

-Forbidden—The interface is not allowed to join the VLAN even from
GVRP registration. When a port is not a member of any other VLAN,
enabling this option on the port makes the port part of internal VLAN
4095 (a reserved VID).
-Excluded—The interface is currently not a member of the VLAN. This is
the default for all the ports and LAGs. The port can join the VLAN through
GVRP registration
-Tag g e d —Select whether the port is tagged. This is not relevant for
Access ports.
-Untagged—Select whether port is untagged. This is not relevant for
Access ports.
-PVID—Port PVID is set to this VLAN. If the interface is in access mode or
trunk mode, the device automatically makes the interface an untagged
member of the VLAN. If the interface is in general mode, you must
manually configure VLAN membership.
STEP 5 Click Apply. The settings are modified and written to the Running Configuration
file.
STEP 6 To see the administrative and operational VLANs on an interface, click Details.
GVRP Settings
Adjacent VLAN-aware devices can exchange VLAN information with each other
by using the Generic VLAN Registration Protocol (GVRP). GVRP is based on the
Generic Attribute Registration Protocol (GARP) and propagates VLAN information
throughout a bridged network.
Since GVRP requires support for tagging, the port must be configured in Trunk or
General mode.
When a port joins a VLAN by using GVRP, it is added to the VLAN as a dynamic
member, unless this was expressly forbidden in the Port VLAN Membership page.
If the VLAN does not exist, it is dynamically created when Dynamic VLAN creation
is enabled for this port (in the GVRP Settings page).
