270 GVRP Commands
Command Mode
Interface Configuration (Ethernet, Port-Channel) mode
User Guidelines
An Access port cannot join dynamically to a VLAN because it is always a member of only one
VLAN.
Membership in untagged VLAN would be propagated in a same way as a tagged VLAN. In such
cases it is the administrator’s responsibility to set the PVID to be the untagged VLAN VID.
Example
The following example enables GVRP on ethernet 1/g8.
console(config)#interface ethernet 1/g8
console(config-if-1/g8)#gvrp enable
gvrp registration-forbid
Use the gvrp registration-forbid command in Interface Configuration mode to deregister all
