Strange process eating CPU 3550

[danne]

Hi,

We have a Cisco 3550 EMI running layer 3 ( OSPF , static routing, HSRP )

The cpu is constantly running around 25-30% even when idle.

This process is the bad guy :

CPU utilization for five seconds: 28%/0%

3436 27.01% 27.92% 27.92% 0 VegasPM

Anyone know what this is ?

The VegasPM process manages the Gigastack GBIC operation on the switch. As each GBIC is inserted, the CPU jumps between 4-6% for each additional GBIC. This is even without the GBIC having any cabling connected. Ultimately, it is a hardware design limitation. However, this does not affect switch performance or traffic forwarding whatsoever.

Have a look at CSCdx90515 for more info. Also documented here:
