9.1 RMON Overview
As an important enhanced function of SNMP, Remote Network Monitoring (RMON) can
monitor overall subnet traffic information on the Ethernet and token ring network.
The RMON module provides the following functions:
l
Configured with the statistics function, it monitors the basic traffic of the specified
subnet.
The traffic information refers to traffic data regularly obtained by RMON.
l
Configured with the history function, it records traffic information on the specified
subnet during the specified interval.
A short sampling interval can be configured to view a sudden traffic change on a
subnet. A long interval can be configured to view long-term traffic status of a subnet.
l
Configured with the event function, it handles alarm messages by recording them
or/and sending Trap messages, so that network administrators can know system
conditions in time.
l
Configured with the alarm function and the corresponding event function, it shows the
changes of specified variables such as sysUPTime.0, which is a MIB variable.
If an alarm item is configured, not less than 500 CRC errors (that is, the threshold is
500) that appear in 5 min trigger an alarm. In this case, if the corresponding event is
configured as sending a Trap message, a Trap message is sent to the Trap server.
To send Trap messages successfully, you also need to correctly set the IP address
of the Trap server and a community string for SNMP and to enable the SNMP Trap
sending function.
9.2 Configuring RMON
This chapter describes how to configure the RMON function.
