Dear Forum,
I am using Ubuntu Linux 9.0.4 and Nagios 3.2.0.

Snmp is installed at my machine and configured and its seems its working fine to check the uptime of a switch 'Uptime' it shows the right status and displays SNMP OK.....); it's has configured as below:
service_description Uptime
check_command check_snmp!-C public -o sysUpTime.0

However if I use another service (for port status) as below, it show SNMP Critical (down 2) always AND I need help for troublehsooting this:
service_description Port 1 Link Status
check_command check_snmp!-C public -o ifOperStatus.1 -r 1 -m RFC1213-MIB

Thanks

Do you know if ifOperStatus.1 is supported on the switch? Not all MIBs are
supported by all devices. I believe that snmpwalk will let you know what
MIBs are available on a particular device.

Thanks for the replies. I have implemented nearly as mentioned by 'cola' but still I am facing the problem.

I have to monitor the Uptime Switches (4948 and 3750 )(Uptime) and the Switchports-Status( Port 1 Link Status) and MRTG also.Only Uptime is working.
