Configuring VLAN Interface Settings

The Interface Settings page displays and enables configuration of VLAN-related parameters for all interfaces.

To configure the VLAN settings:

1. Click VLAN Management > Interface Settings.
2. Select an interface type (Port or LAG), and click Go. Ports or LAGs and their VLAN parameters are displayed.
3. To configure a Port or LAG, select it and click Edit.
4. Enter the values for the following fields:
Interface—Select a Port/LAG.
• Interface VLAN Mode—Select the interface mode for the VLAN. The options are:
General—The interface can support all functions as defined in the IEEE 802.1q specification. The interface can be a tagged or untagged member of one or more VLANs.
• Access—The interface is an untagged member of a single VLAN. A port configured in this mode is known as an access port.
• Trunk—The interface is an untagged member of one VLAN at most, and is a tagged member of zero or more VLANs. A port configured in this mode is known as a trunk port.
• Customer—Selecting this option places the interface in QinQ mode. This enables you to use your own VLAN arrangements (PVID) across the provider network. The device is in Q-in-Q mode when it has one or more customer ports. See QinQ.
• Administrative PVID—Enter the Port VLAN ID (PVID) of the VLAN to which incoming untagged and priority tagged frames are classified. The possible values are 1 to 4094.
• Frame Type—Select the type of frame that the interface can receive. Frames that are not of the configured frame type are discarded at ingress. These frame types are only available in General mode. Possible values are:
Admit All—The interface accepts all types of frames: untagged frames, tagged frames, and priority tagged frames.
• Admit Tagged Only—The interface accepts only tagged frames.
• Admit Untagged Only—The interface accepts only untagged and priority frames.
• Ingress Filtering—(Available only in General mode) Select to enable ingress filtering. When an interface is ingress filtering enabled, the interface discards all incoming frames that are classified as VLANs of which the interface is not a member. Ingress filtering can be disabled or enabled on general ports. It is always enabled on access ports and trunk ports.
5. Click Apply. The parameters are written to the Running Configuration file.
