Creating VLANs

Device Manager enables you to create a port-based, source IP subnet-based, protocol-based, or source MAC-based VLAN.

When creating VLANs using Device Manager, keep in mind the following rules:

VLANs must have unique VLAN IDs and names.
Trunk (tagged) ports can belong to multiple VLANs and multiple spanning tree groups.
A VLAN cannot belong to multiple spanning tree groups.
An access (untagged) port can belong to one and only one port-based VLAN or it can belong to one and only one policy-based VLAN for the given protocol.
If you enable tagging on a port that is in a VLAN, the spanning tree group configuration for that port is lost.
A frame's VLAN membership is determined by the following order of precedence: VLAN ID, then source MAC-based VLAN, then IP subnet-based VLAN, then protocol-based VLAN, then port-based VLAN.
You cannot rename or delete the Default VLAN (VLAN ID 1), and you cannot change its type from port-based VLAN.
