what's the reason of 7603 high cpu per minutes???

Hi Liang,

CPU is high due to interrupts:

CPU utilization for five seconds: 70%/61%; one minute: 17%; five minutes: 15%

So 7-% is total utilization - 61% of total taken by interrupts which are basically traffic sent to processor.

You can use the following document to see which packets are punted to CPU and then eliminate those.

Let me know if any further help needed.

Re: what's the reason of 7603 high cpu per minutes???

basically traffic sent to processor?

but my router is not connected with any device,is a cold standy.Also,the active router have the same problom that is the cup high in the short milisecond per minites

what's the basically traffic can couse the cup high in the short milisecond per minites?

can you say more detail?thanks very much!

what's the reason of 7603 high cpu per minutes???

Hi,

1. What card you are using ?

2. What is the total bandwidth terminating on the box ?

In production, generally I have noted that we overload the box with maximum bandwidth it can support.

Quick and dirty way to decrease the utilization is to enable the ip cef on all interfaces, if you don't have that already.

Hi Liang,

Nikolay put you on the right track, there is traffic sent to the RP. You need to follow the suggestions given and troubleshoot it. There is no point in asking again what is the cause of it if you don't investigate what is being sent to the CPU first.

Quickesy way is to check:

  • show ibc - taken a couple of times with 30 secs interval
  • sniff the CPU using netdr command. THIS DEBUG IS SAFE!! NO CPU OVERHEAD ADDED.
          debug netdr capture rx
          show netdr captured-packets  - collect all the outputs of this command.


Paste the outputs here for me to check.

Riccardo
