Ciscoworks 2.6 Spikes SUP CPU

Unanswered Question
May 15th, 2008

Hello all,

I'm running Ciscoworks 2.6 with the latest updates. Some people have noticed that our SUP modules (sys32,720) CPU are spiking to 90-100% for around 5-10 seconds. This looks like it's happening when ciscoworks is going out to poll the devices.

People are assuming that this is the problem with some percieved network slowness that we were having in the past 2-3 weeks. They cannot pinpoint the issue and cannot recreate it.

The Ciscoworks server has been up for almost 2 years without any issues.

My question is if the SUP CPU spikes for 5-10 seconds is that really an issue? or is it part of the way it's supposed to work? I would be more understanding if the CPU was constantly at 50-60 percent but it's not. It's always between 1-10%.

Thanks

-Nick

I have this problem too.

There's a lot of CiscoWorks that "polls" devices. It would help to correlate what is being polled when the CPU spikes. A sniffer trace filtering on all traffic to one affected switch when the CPU spikes would be helpful.
