VLAN Interface Settings

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

To configure the VLAN settings, follow these steps:

Procedure

Step 1

Click VLAN Management > Interface Settings.

Step 2

Select an interface type (Port or LAG), and click Go. Ports or LAGs and their VLAN parameters are displayed.

Step 3

To configure a Port or LAG, select it and click Edit.

Step 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:

  • 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.

  • 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.

  • Dot1q-Tunnel—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 dot1-q-tunnel ports.

Frame Type

(Available only in General mode) Select the type of frame that the interface can receive. Frames that aren’t of the configured frame type are discarded at ingress. 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 isn’t a member. Ingress filtering can be disabled or enabled on general ports. It’s always enabled on access ports and trunk ports.

Administrative PVID

PVID for selected VLAN mode.

Uplink

(Available only in Trunk mode). Check Enable to set the interface as an uplink port.

TPID

(Available only in Trunk mode) If Uplink is enabled, select the TPID value for the interface.
Step 5

Click Apply.
