Figure 29. Allowed VLANs Configuration (Hybrid)
Forbidden VLANs
A port may be configured to never be a member of one or more VLANs. This is particularly useful when dynamic
VLAN protocols such as MVRP and GVRP must be prevented from dynamically adding ports to VLANs.
VLAN protocols such as MVRP and GVRP must be prevented from dynamically adding ports to VLANs.
The trick is to mark such VLANs as forbidden on the port in question. The syntax is identical to the syntax used in
the Existing VLANs field.
the Existing VLANs field.
By default, the field is left blank, which means that the port may become a member of all possible VLANs.
