Configuring VLANs Assigning Ports to Multiple VLANs 6 - Tagged - Indicates the interface is a tagged member of a VLAN. All packets forwarded by the interface are tagged. The packets contain VLAN information. - Exclude - Excludes the interface from the VLAN. However, the interface can be added to the VLAN through GARP. - Forbidden - Denies the interface VLAN membership, even if GARP indicates the port is to be added. STEP 3 Define the relevant fields. STEP 4 Click Apply. VLAN Membership is modified, and the device is updated. Assigning Ports to Multiple VLANs A port can be configured as a untagged or tagged port member of a VLAN. A port can be port members of multiple VLANs. By default, all ports are assigned to VLAN 1 as untagged port member. All intermediate VLAN-aware devices carrying VLAN traffic along the path between any end nodes must be either configured with the VLAN port memberships manually by an operator or dynamically learnt from GVRP. The untagged port membership configured between two VLAN aware devices that have no other VLAN aware device in between should be to the same VLAN. Otherwise, traffic will leak from one VLAN to another VLAN. VLAN tagged frames can pass through VLAN-aware or VLAN-unaware network interconnection devices. If none of the intermediate network devices to an end node support VLAN, then the port on the last device that reaches the end node must be untagged VLAN member. The VLAN To Port Page contains fields for configuring VLANs to ports. The network administrator allows the user to assign a single port to multiple VLANS.
