network management. NMS obtains the network management information by visiting the MIB
of SNMP Agent.
The switch can operate as a SNMP Agent, and supports both SNMP v1/v2c and SNMP v3.
The switch supports basic MIB-II, RMON public MIB and other public MID such as BRIDGE
MIB. Besides, the switch supports self-defined private MIB.
2.4.3 Introduction to 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).
