Debugging GVRP
GVRP Configuration
Example
When a Trunk port is set as fixed, the port is not allowed to dynamically
■
register/deregister a VLAN, it only propagates information about static VLANs
that are manually configured instead of that of dynamic VLANs. That is, a Trunk
port that is of fixed type only permits manually configured VLANs even you
configure it to permit all VLANs.
When an Ethernet port is set to be in forbidden registration mode, all the
■
VLANs except VLAN1 will be deregistered and no other VLANs can be created
and registered on this port.
Perform the following configuration in Ethernet port view.
Table 65 Set the GVRP registration type
Operation

By default, GVRP registration type is normal.
After the above configuration, execute the display command in any view to
display the running of GVRP configuration, and to verify the configuration.
Execute the debugging command in user view to debug the configuration of
GVRP.
