We use many Products of the mguard series (routers/security appliances) from the Vendor Phoenix Contact.
As of now devices from this vendor are not officially supported from solarwinds.
Which makes it quite an effort to manually integrate those.
It would be great if they would be supported out of the box in the near future.
I was provided with a MIB file, I think that would help integrating in Solarwinds.
