Passport 1000 routing switch VLANs

A VLAN is a collection of ports on one or more switches that define a broadcast domain. Passport 1000 Series routing switches support four types of VLANs:

• Port-based VLANs
• Source IP subnet-based VLANs
• Protocol-based VLANs
• Source MAC address-based VLANs

For further discussion of the types of VLANs and the VLAN rules, refer to Networking Concepts for the Accelar 1000 Series Switch Release 2.0.

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, the IP subnet-based VLAN, then protocol-based VLAN, then port-based VLAN.
• The Default VLAN (VLAN ID 1) cannot be renamed or deleted, and it cannot have its type changed from port-based VLAN.
