Working with VLANs

For information about configuring IP routing on a VLAN, refer to Reference for the Passport 8000 Series Management Software Routing Operations Release 3.1.

A VLAN is a collection of ports on one or more switches that define a broadcast domain. Passport 8000 Series switches support up to 2000 VLANs.

Passport 8600 modules support four types of VLANs:

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

Passport 8100 modules support two types of VLANs:

· Port-based VLANs

· Protocol-based VLANs

For further discussion of the types of VLANs, refer to Networking Concepts for the Passport 8000 Series Switch Release 3.1.

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

• The ports in a VLAN or MultiLink Trunk must be a subset of a single spanning tree group.
• VLANs must have unique VLAN IDs and names.
• An access (nontagged) port can belong to one and only one protocol-based VLAN for a given protocol.
• An access (nontagged) port can belong to one and only one 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.
