And download the MIBs and the load on the server of NetSight but as I do for loading or asosiarlas the device?
There are some technical guidance as asosiar the MIB with devices of different brands in NetSight ?
You should not need to associate a MIB with a particular device. Have you tested that the MIB is correctly loaded by entering an OID in the "Find what" field?
In the 'Find What' field about half way down on the left enter a MIB Object from the MIB that you were trying to import. Click on Find. This will confirm the MIB was imported properly, if you are taken to that location in the MIB Tree then the MIB was imported successfully.
