Figure 1: Screenshot of the error message: Busy network, no route, or snmpd is unresponsive.

Cause

This issue is due to the stuck background process between the Supervisor cards, and it has to be refreshed. This issue is seen after switch upgrades.

Resolution

Follow the steps below:

  1. Check the output of the below command: 
# show snmp user

If the user privilege of the SNMP user is set to YES, change the SNMP user privilege to NO.

If after changing the SNMP privilege the issue is unresolved, follow step 2.

  1. If the privilege is set to NO, then check if the user has DCNM installed in their environment.

If yes, restart the service and try to launch Device Manager to check if the issue resolves.

If after restarting the service the issue is unresolved, follow step 3.

  1. If none of the above steps resolves the issue or are unsuitable to the scenario, perform a system switchover to resolve the issue.
NOTE:
  • For Blade chassis model, Switch #reload has to be performed under a planned maintenance window which is disruptive since the switch reloads.
  • For Director chassis: Use the below command which is a nondisruptive command:
 #system switchover 

Additional Information

NOTE: Increasing the SNMP timeout does not resolve the issue.
