Hi

Please help me on how to monitor cisco switches and routers through SNMP, I am trying to define given below command it is showing error.

./check_snmp -H X.X.X.X -P 2c -c snmp@123! -o sysUpTimeInstance

Error: External command error: Timeout: No Response from X.X.X.X:161.

Thanks and Regards,

I believe instead of "-c" you need to have "-C" in order to pass the community string. The low case "-c" is for the critical threshold...
Can you run the snmpwalk against this device?
Is UDP port 161 open?

Thank you for your help now it is working fine.
