cisco prime infrastructure 1.3 makes every 15 minutes cpu high on cisco 800 routers

I have an issue with cisco prime infrastructure 1.3 and cisco 880 routers, every 15 minutes the cpu goes to 100% on those routers, but I cannot find the job on the prime which is causing this, if I look in the job dashboard I have some jobs like sam_poller_22_15_getvpnpoller_27977292 that runs every 15 minutes (other jobs that I see CDBPoller_dmvpnPoller and CDBPoller_getvpnpoller)   , probably is it on of these jobs, but how can I stop it (job type : poller job, owner =system) and what are they doing?

thanks for any assistance

This is what i expected. I know many platform like 29xx/39xx or ISR's has known issues with Cisco Prime Infrastructure when it polls CISCO-LICENSE-MGMT-MIB, devices go high on CPU.

You have to block clmgmtLicenseInfoEntry by creating a view on your 800 router by configuring snmp view.

Following is the command/example:

Step 1: Configure SNMP View:


snmp-server view iso included

snmp-server view   clmgmtLicenseInfoEntry excluded

Link community string to SNMP View:

snmp-server community view ro|rw

Example per your configuration:

snmp-server view PrimeInfra iso included

snmp-server view PrimeInfra clmgmtLicenseInfoEntry excluded

snmp-server community ArgSnmp view PrimeInfra RO ACLSNMP_RO

OR you can try following on your Cisco PI:

Manually update file below,

Open the /opt/CSCOlumos/conf/sam/template.xml, modify the template id=20  (licensePoller)

Update tag for value 600 to 86400 for all attrributes () of

template id =20

Old: 600

New: 86400

Some known bugs on such issues are :

CSCug97914 and CSCuc72024

Please check and let me know the updates.

It is usually SNMP polling which should be responsible for taking the CPU high. We usually dont need to stop/disable anything on NMS tools, but infact we can have devices troubleshooted to find which is causing high CPU.

Please collect following outputs when you see high CPU :

> show proc cpu sort | exclude 0.00

> show stacks <PID>

     ***PID should be the Process ID (PID) of process taking highest CPU.

Suspected is mostly SNMP, in case so, please share show run | incl snmp output, as well as show log.

the log is saying nothing usefull

the cpu is only 1 or 2 minutes for 100%

thanks for the assistance

Re:cisco prime infrastructure 1.3 makes every 15 minutes cpu hig

One more detail that is essential is the output of show version from the device.

It would be required to decode the tracebacks, show stacks have produced.
