General Rules
to Creating a
Tagged VLAN
Below is a summary of the rules to observe when creating a tagged
VLAN.
❑ Each tagged VLAN must be assigned a unique VID. If a particular
VLAN spans multiple switches or stacks, each part of the VLAN on
the different switches or stacks must be assigned the same VID.
❑ A tagged port can be a member of multiple VLANs.
❑ An untagged port can be an untagged member of only one VLAN
at a time.
❑ The AT-8024, AT-8024GB, and AT-8026FC switches can support up
to 32 tagged VLANS.
