What is the native VLAN role in spanning tree functionality on the Aruba controller?

Aruba Employee

Product and Software: This article applies to all Aruba controllers and ArubaOS 3.x.

 

If BPDUs are only being sent and are not being received and the Aruba controller declares itself as the Root, it means that the controller is not participating in the spanning tree.

 

To make an Aruba controller participate in the spanning tree, you must make sure that the trunk link to the other Cisco switches allows the native VLAN. This configuration is necessary because Aruba controllers do not support per VLAN spanning tree and they use the native VLAN (VLAN1) as the base VLAN for calculating the spanning tree.
