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:
