46 CHAPTER 3: VLAN CONFIGURATION
Setting the GVRP Registration Type
The GVRP includes normal, fixed, and forbidden registration types (see IEEE
802.1Q).
■ When an Ethernet port registration type is set to normal, the dynamic and
manual creation, registration, and logout of VLAN are allowed on this port.
■ When one trunk port registration type is set to fixed, the system adds the port
to the VLAN if a static VLAN is created on the switch and the trunk port allows
VLAN passing. GVRP also adds this VLAN item to the local GVRP database, one
link table for GVRP maintenance. However, GVRP cannot learn dynamic VLAN
through this port.
■ When an Ethernet port registration type is set to forbidden, all the VLANs
except VLAN1 are removed and no other VLANs can be created or registered
on this port.
Perform the following configurations in Ethernet port view.
By default, the GVRP registration type is normal.
Displaying and Debugging GVRP
After you set the GVRP registration type, execute the display command in all
views to display the GVRP configuration and to verify the effect of the
configuration.
Execute the debugging command in user view to debug the configuration of
GVRP.
Example: GVRP
Configuration Example
Set network requirements to dynamically register and update VLAN information
among switches.
