[c-nsp] SNMP process 45%

[Bill Blackford]

What is being polled is something to look at. I had an SNMP poller getting the route table and at a couple of full feeds, that seemed to be enough to add a high CPU load. (C7600/RSP720) 

I can second the ACL to limit who can poll.

Is it that you don't understand why your cpu is at 100% when SNMP is only
chewing 45% and the other processes don't make up the difference?

Just to clear it up in case that is your question...

Your "sh proc cpu sort" looks like:

*CPU utilization for five seconds: 99%/49%; one minute: 99%; five minutes:
99%*

So the 5 second interval "99%/49%" is saying you are using 99% of the CPU of
which 49% is at interrupt(ie your normal cef switched traffic), you have a
remaining 50% being used by processes as seen in the list:

PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process
 231     4428660   3798727       1165 46.12% 45.46% 44.28%   0 SNMP ENGINE
 73   198346604 837505469        236  0.55%  0.52%  0.56%   0 IP Input
 245   278646264 832638396        334  0.47%  0.40%  0.40%   0 BGP Router

So i'm sure if you added up all your processes there you would find it
equals that 50%

Now given your 1 and 5 minute CPU utilization is at 99% and more
specifically your "SNMP ENGINE" process is at ~45% for 5 min avg your real
problem here(as other people have mentioned) is SNMP, you need to check out
what devices are polling your router and sort it out.

Once you resolve the snmp issue you can expect the cpu to drop to around
50-55%
