Syntax Description
Defaults The default administrative control is normal.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines When you set VLAN registration, you are communicating to the switch that the VLAN is interested in
the users that are connecting to this port and that the VLAN’s broadcast and multicast traffic is allowed
to be sent to the port.
For static VLAN configuration, you should set the mod/port... control to fix ed or forbidden if the
mod/port... will not receive or process any GVRP message.
For each dynamically configured VLAN on a port, you should set the mod/port... control to normal
(default), except for VLAN 1; GVRP registration mode for VLAN 1 is a lways fixed an d is not
configurable. VLAN 1 is always carried by 802.1Q trunks on which GVRP is enabled.
When GVRP is running, you can create a VLAN through a GV RP tr unk po rt o nl y if y ou en te r t he se t
gvrp dynamic-vlan-creation enable and the set gvrp registration normal commands.
