Accelar 1000 routing switch VLANs

A VLAN is a collection of ports on one or more switches that define a broadcast domain. Accelar 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, refer to Networking Concepts for the Accelar 1000 Series Routing Switch - Software Release 2.0.

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

• The ports in a VLAN or Multi-Link 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 multiple IP-subnet-based VLANs.
• An access (nontagged) port can belong to one and only one port-based VLAN.
• A frame's membership in a source IP-subnet-based VLAN takes precedence over a protocol-based VLAN, which takes precedence over a 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.
