If no MIB definition files nor roots are loaded, ScanEngine Explorer will work with MIBs on a completely numeric OID basis. For example, were no roots nor MIB definition files loaded, a message containing 2 objects (ifInOctets.1 and ifOutOctets.1) would display as shown.
220.127.116.11.18.104.22.168.1.10 is the OID for ifInOctets, and 22.214.171.124.126.96.36.199.1.16 is the OID for ifOutOctets, but one would only know that by checking an on-line OID definition resource.
Loading module names as roots is better, loading the MIB definition file for the MIBs module is the best. These alternatives are described in the next sections.
