General Rules
for Creating a
Tagged VLAN
Below is a summary of the rules to observe when you create a tagged
VLAN.
❑ Each tagged VLAN must be assigned a unique VID. If a particular
VLAN spans multiple switches, each part of the VLAN on the
different switches 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.
❑ An AT-9400 Series switch can support up to 255 tagged VLANS.
