RMON (Remote Networking Monitoring) enables the switch to proactively monitor
traffic statistics over a given period and send traps to a remote log server. The
switch compares real-time counters against predefined thresholds and generates
alarms, without the need for polling by a central management platform. If you have
correctly set the thresholds relative to your network's base line, this is an effective
management mechanism.
RMON decreases the traffic between the manager and the switch, because the
remote log server does not have to frequently poll the switch for information, and it
enables the manager to get timely status reports, because the switch reports
events as they occur.
With this feature, you can perform the following actions:
•
View statistics (counter values) as they are currently, meaning since the last
time they were cleared.
