RMON configuration task list
Configuring the RMON statistics function
RMON statistics function can be implemented by either the statistics group or the history group, but the
objects of the statistics are different. You can choose to configure a statistics group or a history group
accordingly.
• A statistics object of the statistics group is a variable defined in the Ethernet statistics table, and the
recorded content is a cumulative sum of the variable from the time the statistics entry is created to
the current time. Perform the tasks in Table 20 to configure RMON Ethernet statistics function.
• 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
Configuring 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 various traffic
statistics on the interface, including network collisions, CRC alignment errors,
undersize/oversize packets, broadcasts, multicasts, bytes received, and packets
received. The statistics are cleared at a reboot.
IMPORTANT:
Only one statistics entry can be created for 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.
Perform the tasks in
Table 22 to configure RMON alarm function.
