Hi all,
I´m setting up our new PI 1.2. After we discovered devices and successfully added, PI started to hit CPU devices every 10 minutes, when SNMP poll runs.
CPU utilization for five seconds: 99%/11%; one minute: 29%; five minutes: 17%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
272 23536856 1524766 15436 86.62% 17.07% 5.06% 0 SNMP ENGINE
Is there any custom field to prevent this kind of snmp abuse on our devices?
If you need any further information, please let me know.
Regards

Hi Javier,
Did you manage to find a solution to this issue?
i'm facing the same problem with PI1.2 but i noticed it's releated to the router IOS image, it occurs only on 15.0(1)M8 where on 12.2(24)T4 it won't.
i wonder...

I will look for a router with IOS 12.something and I will perform some test. But for me, It´s something related to IP or routing table mib.
I´ll keep you aware.

Hi,
Well, I finally found a router with 12.something IOS and It´s working fine by now.
What I did on the router with IOS 15 was to make an snmp view like this:
snmp-server view myview iso included
snmp-server view myview at excluded
snmp-server view myview ip.22 excluded
snmp-server community xxxxxx view myview RO SNMP-ACL
I took this from a "similar bug"
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCta43825&from=summary
It seems to be some bug related to ARP table entry or something like that..
