Nagios Support Forum

Hi;

I just want to ask assistance on the issue when a switch or router is being enrolled in NagiosXI it scans the ports in the device, but once the device has been reboot/restart Nagios won't re-scan the device and update the configuration that has indexing or port number. So when there is an activity in a switch or router, some ports will alarm and then checked it in the device those ports are UP and since the index # in the configuration is not updated, Nagios considered it as down.

The indexing would need to remain persistent(check the switch/router documentation) or you would need to manually run the wizard again to get the new indexes.

Thank you. So basically, the normal behavior of router/switch after restart should not change the index number, right? I just want also to confirm if we try to rerun again the wizard it will not duplicate? or do we need to delete it first in CCM?

You will want to delete it in the CCM first.

Okay noted. Is there an option that we can set in the router/switch so that the index will not change after reboot?

Thanks

Hi @Brezner,

That would depend on the router/switch. Check the manufacturer's documentation for setting a persistent interface index across reboots.
