Engage the device administrator and/or Vendor to resolve the problem. Once the ifTable MIB OIDs and values are present for queries and polling discovery and subsequent metric polling should begin to work properly.
Use the SAPWALK2, snmpwalk or other snmp tools to query the ifTable OIDs. If they don't exist or fail to respond the device is the root of the problem.
