Port-based VLAN
Guidelines
The following is a summary of general guidelines to observe when
creating port-based VLANs:
Each port-based VLAN must be assigned a unique VID.
Each port must be assigned a PVID. This value is assigned
automatically by the AT-S67 and AT-S68 management software.
The value is the same for all ports in a port-based VLAN and is
identical to the VLAN’s VID, except when using the special VLAN
configuration feature.
If there are end-nodes in different VLANs that need to
communicate with each other, a router or Layer 3 switch is
required to interconnect the VLANs. In this case, each VLAN must
have it’s own port connection to the router. The special VLAN
configuration feature will not facilitate inter-VLAN
communication.
