The port mode for each port or LAG is displayed with its current port mode
(Access, Trunk or General) configured from the Interface Settings Page.
Each port or LAG is displayed with its current registration to the VLAN.
STEP 3 Change the registration of an interface to the VLAN by selecting the desired
option from the following list:
• Forbidden—The interface is not allowed to join the VLAN even from GVRP
registration. When a port is not a member of any other VLAN, enabling this
option on the port makes the port part of internal VLAN 4095 (a reserved
VID).
• Excluded—The interface is currently not a member of the VLAN. This is the
default for all the ports and LAGs. The port can join the VLAN through GVRP
registration.
• Tagged—The interface is a tagged member of the VLAN. Frames of the
VLAN are sent tagged to the interface VLAN.
• Untagged—The interface is an untagged member of the VLAN. Frames of
the VLAN are sent untagged to the interface VLAN.
• PVID—Select to set the PVID of the interface to the VID of the VLAN. PVID is
a per-port setting. You can only configure the PVID of General ports.
STEP 4 Click Apply. The interfaces are assigned to the VLAN, and the switch is updated.
You can continue to display and/or configure port membership of another VLAN
by selecting another VLAN ID.
Configuring VLAN to Port
Use the VLAN To Port Page to map ports to multiple dynamic VLANs.
To assign a port to multiple VLANs:
STEP 1 Click VLAN Management > VLAN to Port. The VLAN To Port Page opens.
STEP 2 Select interface type (Port or LAG), and click Go. The following fields are
displayed for all interfaces of the selected type:
• Interface—Port/LAG ID.
• Mode—Interface VLAN mode that was selected in the
Interface Settings
Page.
