Resolution

The issue is with the device itself. The error - "Got endOfMIBView", means that Spectrum is querying the device for OIDs that the device's agent cannot understand.

Check for updated MIBs and firmware for the device and if neither are available, contact the Vendor (in this case - Fortinet) to fix their agent/MIB.
