Tag-based:
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. For more
details, please see the section VLAN in Chapter 3.
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
4094 Tag VLAN groups.
