RMON Overview 81
■Required if traps are to be sent — the IP address of the interface ethernet 0 is
the source address of the traps, and the address of the NMS is the destination
address.
II. Networking Diagram
Refer to the networking diagram of Example 1.
III. Configuration Procedure
1Enable the router to support SNMP and select an SNMP version.

RMON Overview RMON (Remote Monitor) is a MIB defined by IETF and is the most important
enhancement for the MIB II standard. It mainly monitors the data flow in a
network segment or on the entire network. It is implemented on the basis of the
SNMP architecture (one of its strengths), including NMS and Agent running on
network equipment.
RMON Agent performs statistics of diversified flow information on the network
segments connected to the ports, such as the total messages on a network
segment within a certain period or the total of correct messages sent to a host. It
enables SNMP to monitor remote network devices more efficiently and more
actively and provides an efficient method to monitor sub-network running. This
method can help reduce communication flows between the NMS and the Agent,
