switchport forbidden vlan
The switchport forbidden vlan Interface Configuration mode command forbids adding specific
VLANs to a port. This may be used to prevent GVRP from automatically making these VLANs
active on the selected ports. To revert to allowing the addition of specific VLANs to the port, use
the remove parameter for this command.

non-consecutive VLAN IDs with a comma and no spaces. A hyphen designates a range of
