High CPU Utilization on the 5509

The RSM CPU utilization on the 5509 Catalyst switch was running very high at all time between 60% and 99% I checked everything that I can think of.

Please advice me with steps that I can follow to isolate the problem. I included show ver to define the IOS ver and the mem size.

Hi

You can offload the RSM workload by enabling the MLS and the CEF.

I have faced the same problem on the 6509 and drop down to 5% immediately after I enabled the MLS.

Dear Mr. WILLIAM WONG

I appreciate your respond. I found out that the 55009 Catalyst doesn’t have the NetFlow Feature Card installed in the Supervisor III mod, I thought that the MLS dose not work with out having the NetFlow Feature Card is that right?

The CEF was enabled on the interfaces and Globally.

Re: High CPU Utilization on the 5509

Is there any particular process hogging most of the CPU?

Re: High CPU Utilization on the 5509

Do a show proc cpu and see what is driving the cpu . then do a show interface and see if any particular port or vlan has high utilization . It's possible that you may have a virus if this is something that just popped up . You could try turning on ip cache flow on the interfaces and see if their is a particular address that is showing up a lot and going to many different ip addresses . This is the version that we are running on our Cat5000 RSM's without a problem . CEF should be on by default in this version . Make sure mls is also on , this helps a lot on the CPU as only the first packet hit's the cpu in a flow then all following packets are switched in hardware .

Hi

The 5509 Catalyst doesn’t have the NetFlow Feature Card installed in the Supervisor III G mods.

I have 2 Supervisor III G in each cat. Do I need 2 NetFlow Feature Card for each Supervisor III G mods?
