This study deals with the methodology, realisation and execution of
MIB-2 evaluation tests. The evaluation was limited to approximately 40
separate MIB-2 objects from 5 MIB-2 groups. The correctness and availability
of these objects was determined under a number of test conditions.
One 10 Mbit and two 100 Mbit multiport routers were subject to the evaluation.
The devices were all subject to the same tests relative to their
interface speed. The results from these tests were analysed and a comparison
was made between devices. A few rarities were observed, of which
the following are the most striking. Not all devices are able to maintain a
good MIB-2 functionality under a heavy traffic load. Some objects seem
not to be implemented at all, or in an ambiguous manner. Object implementation
can vary between manufacturers. Some data count objects are
not accurate, or have a structural offset.
