44 C 3: VLAN C
HAPTER ONFIGURATION
Perform the following configurations in Ethernet port view.
Table 12 Enable/Disable Port GVRP
Operation
Enable port GVRP
Disable port GVRP
GVRP should be enabled globally before it is enabled on the port. GVRP can only
be enabled or disabled on a Trunk port.
By default, global GVRP is disabled.
Set GVRP Registration Type
The GVRP registration types include normal, fixed and forbidden (see IEEE
802.1Q).
When an Ethernet port is set to be in normal registration mode, the dynamic
■
and manual creation, registration ,and logout of VLAN are allowed on this port.
When one Trunk port is set as fixed, the system adds the port to the VLAN if a
■
static VLAN is created on the switch and the Trunk port allows the 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. The learned dynamic VLAN from other ports of the local
switch will not be able to send statements to the outside through this port.
When an Ethernet port is set to forbidden registration mode, all the VLANs
■
except VLAN1 are logged out and no other VLANs can be created or registered
on this port.
Perform the following configurations in Ethernet port view.

views to display the running of the GVRP configuration, and to verify the effect of
the configuration. Execute the debugging command in user view to debug the
configuration of GVRP.
