appears.
Figure 4-6-4: VLAN Membership Status for Static User Page Screenshot
The Page includes the following fields:
Enabled VLANs field.
By default, a Trunk or Hybrid port will become member of all VLANs, and is
therefore set to 1-4095. The field may be left empty, which means that the port
will not become member of any VLANs.
A port may be configured to never be member of one or more VLANs. This is
particularly useful when dynamic VLAN protocols like 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 Enabled VLANs field.
By default, the field is left blank, which means that the port may become a
member of all possible VLANs.
