RMON Overview
RMON allows the switch to track events and trigger alarms when a threshold is
reached and to notify administrators by issuing a syslog message or SNMP trap.
The RMON MIB provides an interface between the RMON agent on the switch and
an RMON management application. The RMON MIB is described in RFC 1757.
The RMON standard defines objects that are suitable for the management of
Ethernet networks. The RMON agent continuously collects statistics and proactively
monitors switch performance. RMON allows you to monitor traffic flowing through
the switch.
The switch supports the following RMON Groups, as described in RFC 1757:
„ Group 1: Statistics
„ Group 2: History
„ Group 3: Alarms
„ Group 9: Events
