Rmon Features Of The Dual Speed Hub 500 - 3Com 3C16685 User Manual

One other problem with stand-alone RMON probes is that they are
passive; able to monitor and report, but nothing more. Placing probe
functionality inside the network device allows integration of RMON
with normal device management to allow proactive management.
As an example, statistics can be related to the segments and the unit
can take autonomous actions such as disabling a port on a segment
(temporarily or permanently) if errors on that segment exceed a
pre-defined threshold.

RMON Features of the Dual Speed Hub 500

All nine groups of RMON are supported fully for 10Mbps and
100Mbps segments.
If you have a Dual Speed Hub 500 with a serial number less than
0600/00000000000, upgrading the software to version 2.1x or
above will not give you support for the RMON Filter and Capture
groups on the 100Mbps segments, which means that you cannot
perform RMON Filter Capture for the 100Mbps segments.
