I am using Orion 8.0.1 and have decided to try to find out why I have the following issue (has been around since previous versions, but I'm finally tired of seeing it).
I have enabled SNMP on some PIX firewalls at our regional offices and are monitoring them via Orion. All of my PIX devices are listed as up, and Orion reports "One or more interfaces are in an Unknown state." I see this with some other devices as well (such as an HP Laserjet 8000 printer that reports "HP ETHERNET MULTI-ENVIRONMENT,ROM br29n00,JETDIRECT,JD33,EEPROM G.08.49' is in an Unknown state."
Is there something I'm missing? Or is this behavior normal for these devices? I'd like my "Nodes with Problems" table to only list devices that are actually having problems. 
Thanks in advance.
