2.2 Configuring RMON
This section describes how to monitor the network status and traffic through RMON.
2.2.1 Establishing the Configuration Task
Before configuring RMON, familiarize yourself with the applicable environment, complete the
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
To monitor network status and collect traffic statistics on a network segment, you can configure
RMON.
Enabling the RMON function does not need any special requirement. You can enable it in
advance, or configure it when you suspect that the traffic of the sub-network where interface
resides is abnormal. You can configure RMON depending on actual situations.
It is recommended to configure the statistics table in advance, configure two history control
policies on the interface where the traffic is abnormal, configure the alarm for one or more
suspicious entries, set the high and low thresholds, and view the alarm information.

Table 2-1
shows the capacity of various tables and the maximum time span of each table.
Table 2-1 Time span of each table

NOTE
logTable does not have a time span. Each log entry can have a maximum of 10 pieces of logs. The
excessive logs supersede the older ones in a circular manner.
When an interface board or an interface card is removed, the corresponding entries in the
ethernetStatsTable and historyControlTable become invalid. If the time spans of tables are
respectively set to 1200s, the entries in the tables are deleted when the time spans go down
to 0.
If an interface is added before its corresponding entries are deleted from the table, these
entries can take effect again.
