Why is Solaris 10 sending Spanning Tree BPDU (Bridge Protocol Data Units) to the switchport? (Doc ID 1424705.1)

Last updated on AUGUST 17, 2016

Applies to:

Solaris SPARC Operating System - Version 11 11/11 and later
Information in this document applies to any platform.

Symptoms

Customer's Network Team been working with Brocade. They traced the Spanning Tree issues to a Solaris host port that the access switch thought was the root port for that VLAN.

The Switchport was seeing BPDUs on the port and teh customer thought they were coming from the Solaris host. A BPDU is a spaning tree frame that switches/bridges use to communicate with each other regarding information about the spanning tree(s) topology and state.
