snmp alerts for CPU utilization

[sivakondalarao]

Hi,

I want to enable snmp alerts on l2 and l3 switches to monitor CPU utilization.

I have Opmanager which is acting as SNMP server.

I have switches L2 and L3 which are running IOS 12.0, 12.1, 12.2

Do all these IOS versions support SNMP alerts?

And also I want to know the commands to be configured on switches for this.

Regards

You can configure SNMP traps for CPU Thresholding Notification.

You should be ok with the versions you list but check exact IOS version supports it at http://www.cisco.com/go/fn

If you do not want to use traps then there are specific oids that can be polled for 1minute average (1.3.6.1.4.1.9.2.1.57) and also 5 minute average (1.3.6.1.4.1.9.2.1.58). I've used these in the past with no problems. These oids may have been superceeded so check for latest. You can always snmpwalk a device to check oids.

The cisco SNMP navigator is helpful when it comes to oids.

If you haven't got any SNMP configured yet on the switch check out http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=Network%20Management&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddb4e54
