Two Core CAT 6500 switches running CatOS:
The CPU Utilization of two CAT 6500 CORE switches are constantly showing over 90% CPU Utilization. The main CPU consumer is always SptBpduRx proces on both CAT 6500.
The customer is not having any impact whatsover in terms of network performance and hence I am ruling out the possibilty of any Spanning Tree Loop. He has had this situtaion for a long time.
I seem to recall that if some sort of Spanning Tree Trace is set on CatOS that this could happen, but I am unable to find any details on this tracing.
Any suggestions on why the CPU utilization is so high, especially the SptBpduRX process and yet there is no impact to any user whatsoever in terms of network performance or connectivity.
