monitor network at any time effectively. RMON is helpful for network administrator to manage
the large-scale network since it reduces the communication traffic between management
station and managed agent.
RMON Group
This switch supports the following four RMON Groups defined on the RMON standard
(RFC1757): History Group, Event Group, Statistic Group and Alarm Group.
RMON Group
Function
History Group After a history group is configured, the switch collects and records
network statistics information periodically, based on which the
management station can monitor network effectively.
Event Group Event Group is used to define RMON events. Alarms occur when an event
is detected.
Statistic Group Statistic Group is set to monitor the statistic of alarm variables on the
specific ports.
Alarm Group Alarm Group is configured to monitor the specific alarm variables. When
the value of a monitored variable exceeds the threshold, an alarm event is
generated, which triggers the switch to act in the set way.
The RMON Groups can be configured on the Statistics, History, Event and Alarm pages.
