Hi..

I have Cisco 1921( Version 15.5(1)T1) router and configured SNMP. But SNMP server unable to catch snmp data for 2 minutes from this router. logs are clean and no connectivity issues as well.

Other SNMP enabled devices are working fine with SNMP server and only this device has this issue.

Appreciate if anyone can provide an idea how to t.shoot this or any reason for this.

with the given output we do not have any visibility of your  configuration so my guess thinking some config issue or ACL in place which may have you encounter this problem.

So give you proper advice please share show run.
