Creating a VLAN
When you create VLANs using VLAN Manager, follow these 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.
