High CPU usage when polling Cisco 3750 Switch Stack

Table of contents

Updated June 16, 2017

Overview

This article provides information regarding the CPU usage when polling Cisco 3750 Stack.

Environment

  • NPM 12.0.1
  • Cisco 3750 Stack - IOS Version 12.2(25)

Detail

The SNMP process on the Stack Master switch consumes a high amount of CPU and reboots the switch when polling a Cisco 3750 Stack.

 

Workaround: disable the stack polling on the affect device.

Go to Node Details -> Pollers -> Manage Pollers -> find 'Switch Stack' -> Assignments -> Set it to OFF state on problematic node.
