Parameter description:

VLAN Mode:

Tag-based:

This is the default setting.

Tag-based VLAN identifies its member by VID. This is quite
different from port-based VLAN. If there are any more rules in
ingress filtering list or egress filtering list, the packet will be
screened with more filtering criteria to determine if it can be
forwarded. The switch supports supplement of 802.1q..

Each tag-based VLAN you built up must be assigned VLAN name
and VLAN ID. Valid VLAN ID is 1-4094. User can create total up to
256 Tag VLAN groups.
