I do not know if this is addressed in Orion 8.5.1, we are currently running 8.1.
When we discover the resources for our Digi terminals only the ethernet interface is discovered. However, the MIB walker confirmed that each serial port on the unit has it's own unique O.I.D string.
I would like to see these ports get detected as interfaces the same as the Cisco equipment. The Cisco routers bring back loopbacks, ethernet, serial, async, etc.
Initially for the Digi it would be great to tell the port status, and get some performance charts going to determine errors or a "hung port"
Thanks,
