4.15 RMON
RMON is the most important expansion of the standard SNMP. RMON is a set of MIB definitions, used to define standard
network monitor functions and interfaces, enabling the communication between SNMP management terminals and remote
monitors. RMON provides a highly efficient method to monitor actions inside the subnets.
MID of RMON consists of 10 groups. The switch supports the most frequently used group 1, 2, 3 and 9:
Statistics:
Maintain basic usage and error statistics for each subnet monitored by the Agent.
History:
Record periodical statistic samples available from Statistics.
Alarm:
Allow management console users to set any count or integer for sample intervals and alert thresholds for
RMON Agent records.
Event:
A list of all events generated by RMON Agent.
Alarm depends on the implementation of Event. Statistics and History display some current or history subnet statistics. Alarm
and Event provide a method to monitor any integer data change in the network, and provide some alerts upon abnormal events
(sending Trap or record in logs).
