Hi All,

I was just wondering if anyone knows of ways of monitoring the interfaces on a Cisco router other than using SNMP.

Thanks in advance,
SkyLimit

What do you want to monitor? And why not SNMP?

I want to monitor the interface status i.e. I'd like to know when the interface goes down. I find SNMP to be CPU intensive hence, why I'd like to try something else if this makes sense.

Thanks

I monitor EVERYTHING with SNMP and have found no hit on CPU. I'm not sure you have any other option.

There are two other ways:
1) Write a script in Perl that telnets into the router, issues the relevant show int commands, parses the output and deduces the status. Then run that in a loop for a constant status monitor
2) Rig up something to suspend little photodiodes in front of the interface LEDs and connect them to suitable electronics to alert you if the light goes out.
Both are feasible, both would work but neither are worth it; just use SNMP!
