Rats, I fat fingered that somehow ... likely during my testing/snmpwalking.

Yes, the OID ending in 6 is the one I want.

Now that my typo is out of the way, I receive a zero value for the proper
OID.
.1.3.6.1.2.1.14.1.6 = No Such Instance currently exists at this OID
.1.3.6.1.2.1.14.1.6.0 = Gauge32: 0

I'm able to successfully poll another router and get the proper value
returned.
Both routers are running the same IOS image.


Thanks!
