Configuring VLAN Tagging

In addition to configuring which VLAN tags should be set according to destination local subnet or according to the next-hop router (NHR), you can also retain the existing VLAN tags on the incoming traffic that passes through the device. In addition, you can configure the same VLAN tag on multiple interfaces. You can also configure a VLAN tag on a VLAN interface.

Note	If a packet arrives without a VLAN tag, LinkProof sets a tag according to the destination local subnet.

To configure VLAN tagging and the VLAN Tagging handling method

1.	Select Device > VLAN Tagging. The Virtual LAN Tagging pane is displayed.

2.	Configure the parameters; and then, click Set.

 

Table 55: VLAN Tagging Parameters

Parameter	Description
802.1q environment	Specifies whether the device handles VLAN tags traffic according to IEEE 802.1Q. Values: • Enabled — The device handles VLAN-tagged traffic according to IEEE 802.1Q. • Disabled — The device drops all VLAN-tagged traffic. Default: Disabled
VLAN Tag Handling	Specifies how the device handles VLAN tags. Values: • Retain — The device preserves existing VLAN tags on the ingress traffic that passes through the device. Traffic generated by the device is tagged according to the IP interface configuration. If an ingress packet has no VLAN tag, the device performs VLAN tagging on the egress packet according to the IP interface configuration.    • Overwrite — The device performs VLAN tagging of outgoing traffic according to the IP interface configuration. Default: Overwrite
