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.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:
