High CPU usage

Hi All,

I have a cisco 1841 router at a location.

10 Mb internet link is terminated on this
Both EIGRP (on dmvpn tunnel on internet) and BGP (on MPLS) protocols are running.

Since 10 days I was observing the CPU is touching 50% and nothing process is showing taking more.

Please find the below cpu history:

Re: High CPU usage

Hello Naidu,

Can you please also post the output of the command show processes cpu sorted 5min ?

If you are using IPsec-protected DMVPN then it is possible that the encryption is causing the CPU load spikes. Do you have any hardware module installed in the 1841 to offload the crypto operations?

Best regards,

Peter

Re: High CPU usage

Hi Peter,

Are you saying about any AIM module is installed?

If not what hardware module can I install  to offload the crypto operations?

If i understand you correctly, by installing a hardware module we can move or something the crypto operations on to this so that the router cpu will not get more. Is that correct?

Please find the below cpu output for 5 minutes.

Router#sh proc cpu sorted 5min

Re: High CPU usage

Hi Naidu,

Yes, I was talking about an AIM crypto module. See this document for further information:

http://www.cisco.com/en/US/prod/collateral/routers/ps5853/data_sheet_vpn_aim_for_18128003800routers_ps5853_Products_Data_Sheet.html

Also, you can review the installed hardware in your router using the show diag and show inventory commands.

In any case, do not yet rush into ordering the AIM. So far, I am not convinced that the high load is caused by crypto operations. Your current load was 17%, out of which 16% was in interrupt mode (i.e. fast switching, CEF switching) which is expectable for a normally working router. As we are obviously not in the time of a huge CPU spike, it is hard to tell what is causing it. I personally suggest strongly observing the load in regular intervals, and when the CPU load exceeds 50% then the listing of processes should be captured, preferably sorted by all three  keys (1s, 1m, 5m).

Best regards,

Peter

Re: High CPU usage

Hi Peter,

Sure, I will keep observe the CPU load on regular intervals and will update back to you.

Regards,

Naidu.
