General Rules
for 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 ports on an AT-8400 line card can belong to the same VLAN or
different VLANs.
❑ A port cannot be an untagged and tagged member of the same
VLAN.
❑ An AT-8400 Series switch can support up to 256 VLANs.
