VLAN Interface Settings

A virtual interface that is connected to the physical network port or bond where your VLAN is configured is known as a VLAN interface. The VLAN Interface is used to automatically assign the correct VLAN ID to traffic that is routed over it.

VLAN-related parameters are displayed and configurable on the VLAN Interface Settings page. Use these steps to configure the VLAN settings:

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 and select or enter the port.

Switchport Mode

Select either Layer 2 or Layer 3.

Ethertype Tagging

Select an Ethertype tagging method for the S-VLAN tag.

  • Dot1q-8100

  • Dot1ad-88a8

  • 9100 (old non-standard QinQ ethertype)

  • 9200 (non-standard QinQ ethertype)

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

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.

Primary VLAN

Select the primary VLAN in the private VLAN. The primary VLAN is used to allow Layer 2 connectivity from promiscuous ports to isolated ports and to community ports. If None is selected if the interface isn’t in private VLAN mode.

Secondary VLAN - Host

Select an isolated or community VLAN for those hosts that only require a single secondary VLAN.

Available Secondary VLANs to Selected Secondary VLANs

For promiscuous ports, move all secondary VLANs that are required for normal packet forwarding from the Available Secondary VLANs. Promiscuous and trunk ports can be members in multiple VLANs.

Step 5

Click Apply.
