From the FAQ:
Does the agent support the RMON-MIB?
-----------------------------------
Not really.
There is an "Rmon" code module included within the agent source
code tree, but this is best thought of as a template for the
RMON-MIB statistics groups, rather than a full implementation.
With most MIBs, the hardest part of implementing the MIB is often
getting hold of the data to report. This is definitely true of the
RMON-MIB, which relies on gathering (and analysing) a potentially
large quantity of network traffic. The Rmon code distributed with
the Net-SNMP agent code avoids this problem, by using random data.
Some of the functionality of the RMON-MIB, such as the alarm and
event groups, has since been superceded by the work of the DisMan
IETF working group. The Net-SNMP agent does implement these (more
general) MIB modules. But the statistics gathering aspects of
the RMON-MIB are not readily available.
Note too that none of the core developers have any significant
experience with this code, and the person who originally wrote it
is no longer active on the mailing lists. So there's no point in
asking on the lists whether these modules work or not. You've got
the source - how badly do you need this functionality?
