Products

Issue/Introduction

There is one cisco device for which we are getting failed to SNMP query device alert. Some time back it was working OK. Device is monitored using interface_traffic probe but getting same error using snmpget probe. Snmp v2c.

Environment

Release : 9.0.2

Component : UIM - INTERFACE_TRAFFIC

interface_traffic/snmpget/SNMPwalk

Cause

- device configuration issue (known issue)

Resolution

sh run command when run on the problematic device seemed to hang the first time we ran it.

As per ISE Admin/Cisco TAC Engineer there turned out to be a known issue with Cisco ISE->

CSCuv68628 - ISE 1.3P2 hangs while issue Show Run and stuck to generate support-bundle. - 1

And on the device, we had to issue the command:

   no cdp run

to disable cdp.

Then we could access the device successfully via SNMP/snmpget probe, etc., with no issue.
