I have an SM where I log into the web interface and it says "Down" in red.
Through SNMP, though, it says 1 (up) with the other options being 0 (down) and 2 (disabled). When it's plugged in and the interface is up, it continues to respond with a 1 via SNMP. The OID I am using is:
1.3.6.1.4.1.17713.21.1.4.1.0
This exists in 2.5.1 and 2.5.2. I don't know if Lan2/aux is affected or not, we're not using it anywhere at all.
This really screws up our tier 1 support!
