Cisco router reboot and interface status

dajanx

I experienced a reboot to a cisco router recently due to power loss. The only alert that I received in NPM via syslog was concerning the reboot. It ends up my LAN interface did not recover after this reboot. My thinking is that there is a issue between the router and NPM. The solarwinds server will pickup downed interface during regular operations and alert on them. My thinking is that after a reboot NPM is not creating an alarm for interfaces that were up before the reboot took place. I have the following snmp configuration in my router: snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart.

My only conclusion right now for my NOC, is to login to every router they see a reboot on and confirm LAN interface. An alert would be much more helpful.

Is there anything I am missing here?

What status did NPM show the interface in when it "did not recover"?  That's the key to figuring out why there wasn't an alert.

There is a never ending list of metrics and indicators of unhealthy you could look for in infrastructure.  At some point it makes sense to test the transit traffic and use that as your catch all for discovering problems when all existing infrastructure metrics look healthy.  IP SLA and NetPath are examples of technology that can do that for you.  A simple ICMP node in NPM can work too.
