Configuration Guide Configuring RMON
Overview
Collects statistics on the packet count, byte count, and other data of a monitored Ethernet
interface accumulatively.
Records the counts of packets, bytes, and other data communicated by an Ethernet
interface within the configured interval and calculates the bandwidth utilization within the
interval.
Samples values of monitored variables at intervals. The alarm table is used in combination
with the event table. When the upper or lower limit is reached, a relevant event table is
triggered to perform event processing or no processing is performed.
4.3.1 RMON Ethernet Statistics
Working Principle
The RMON Ethernet statistics function accumulatively collects statistics on network traffic information of an Ethernet
interface from the entry creation time to the current time.

Configuring RMON Statistical Entries
The RMON Ethernet statistics function is disabled by default.
Run the rmon collection stats command to create Ethernet statistical entries on a specified Ethernet interface.
After statistical entries are successfully created on a specified interface, the statistics group collects statistics on the
traffic information of the current interface. The statistical items are variables defined in the RMON Ethernet statistical
table, and recorded information is the accumulated values of variables from the creation time of the RMON statistical
table to the current time.
4.3.2 RMON History Statistics
Working Principle
The RMON history statistics function records accumulated statistics on traffic information of an Ethernet interface within each
interval.
Related Configuration
Configuring RMON Historical Control Entries
The RMON history statistics function is disabled by default.
Run the rmon collection history command to create historical control entries on an Ethernet interface.
The RMON history group collects statistics on variables defined in the RMON history table and records accumulated
values of variables within each interval.
