Unknown Device

Hi,

I imported my devices in the DELL OME 2.0.
I can say that it works pretty well ! :)

However, I have some device in the Unknown category.
Especially one device saying the following error : "Authentication failure"

I noticed myself that I wrote a type regarding the community name so I correct it but the same error appear.
Also I run the SNMP troubleshoot to check if something wrong with the device and everyhing is OK.

Can someone can help me about this issue ?

Thanks,

Lala
