A statistics object of the history group is the variable defined in the history record table, and the

recorded content is a cumulative sum of the variable in each period. Perform the tasks in

Table 21

to configure RMON history statistics function.

Table 20 RMON statistics group configuration task list

Task Remarks

onfiguring a statistics
entry

Required
You can create up to 100 statistics entries in a statistics table.
After a statistics entry is created on an interface, the system collects statistics on

various traffic information on the interface. It provides statistics about network

collisions, CRC alignment errors, undersize/oversize packets, broadcasts,
multicasts, bytes received, packets received, and so on. The statistics are cleared

after the device reboots.

IMPORTANT:

Only one statistics entry can be created on one interface.

Table 21 RMON history group configuration task list

Task Remarks

Configuring a history
entry

Required
You can create up to 100 history entries in a history table.
After an entry is created, the system periodically samples the number of packets
received/sent on the current interface, and saves the statistics as an instance under

the leaf node of the etherHistoryEntry table.

IMPORTANT:

When you create an entry, if the value of the specified sampling interval is identical

to that of the existing history entry, the system considers their configurations are the
same and the creation fails.

Configuring the RMON alarm function

If you need to configure that the managed device sends a trap to the NMS when it triggers an alarm

event, you should configure the SNMP agent as described in SNMP Configuration before

configuring the RMON alarm function.

As the alarm variables that can be configured through Web network management are MIB
variables that defined in the history group or the statistics group, you must make sure that the

RMON Ethernet statistics function or the RMON history statistics function is configured on the
monitored Ethernet interface.

Perform the tasks in

Table 22

to configure RMON alarm function.
