4.6.4 Important Notes for VLAN Configuration

Some considerations should be checked in configuring VLAN settings:

1.Switch VLAN Mode selection

It is suggested to evaluate your VLAN application first and plan your VLAN configuration carefully before applying it. Any incorrect setting might cause network problem.

2.Aggregation/Trunking configuration

Make sure the members of a link aggregation (trunk) group are configured with same VLAN configuration and are in same VLAN group.

3.Double Tagged in Advanced VLAN Mode

For a received packet, Ingress port [Keep Tag] setting and Egress port [Insert Tag] setting are enabled at the same time. It will cause the packet double-tagged when egress. Although, it is often applied in Q-in-Q provider bridging application. However, such condition should be avoided in normal VLAN configuration. See table below:

Ingress port	Egress port
[Keep Tag]	[Insert Tag]	Received Packet	Packet Transmitted
Enable	Enable	Priority-tagged	Double-tagged
Enable	Enable	VLAN-tagged	Double-tagged
