Justin,

Give this a shot:

http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&mibName=CISCO-ICSUDSU-MIB

That MIB contains values for different loop codes.

Ryan,

That looks like a very useful MIB.  I'll give that a try.

I looked at the source of the check_snmp_int.pl script for Nagios as well and noticed that it was built to handle 3 response codes: up, down and testing. On a hunch I looped up an unused T1 on a T3 controller and hit it with a snmpwalk. Sure enough it listed the looped interface as "testing":

IF-MIB::ifOperStatus.28 = INTEGER: testing(3)

check_snmp_int.pl also correctly detected the situation:

Serial1/0/10:0:TESTING: 1 int NOK : CRITICAL

So it looks like that plugin will do what I need if I can figure out how to make it only give a warning if the interface is in testing and not a critical alarm (warning for say 1hr; then escalate it send our alerts). I want it to warn with no email for about an hour. Then escalate it and send our the alerts. Should be doable.

Thanks
 Justin
