Hi,
I have found RMON more useful as a trouble shooting tool particularly on switches.
Non Cisco equipment (Cabletron, 3Com and the like) often have RMON available. You can
usually get into these without any special MIBs and get into the raffic analysis.
RMON allows you to more easily find who and what could be causing congestion or
traffic problems than does SNMP. Be caeful however RMON is quite CPU intensive when
turned on a device. For example, you can expect a 2500 series router to pack it in
within a minute or two if you decide RMON should be on to discover a problem. The
best way is to get some other device to get the RMON stuff for you. An RMON Probe.
You can use RMON Probes on remote sites to do all sorts of useful traffic analysis the
SNMP wont give you.
Just some thoughts
