Get WARNING: Interface is administratively down after reboot

[kimseng]

Hello, I got one problem with Nagios XI after i reboot my router and i got WARNING: Interface TenGigE0/1/0/18 (index 69) is administratively down. but truly this port is up normal. any command?

The interface was likely assigned a new index number(old one being 69) after being rebooted. The check_ifoperstatus command can be configured to check using the interface description instead with the -doption:

/usr/local/nagios/libexec/check_ifoperstatus -d TenGigE0/1/0/18 -H <hostname> -C <community>

Hi,

I still not working and here is a result.

WARNING: Interface TenGigE0/1/0/18 (index 69) is administratively down.

Did you run the command from the command line or did you modify the actual service check config? I'd be curious to see the output from the command line as well as the configuration seen in the web UI.
