RMON configuration task list

Configuring the RMON statistics function

The RMON statistics function can be implemented by either the Ethernet statistics group or the history group, but the objects of the statistics are different, as follows:

•A statistics object of the Ethernet 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.

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

To send traps to the NMS when an alarm is triggered, configure the SNMP agent as described in "Configuring SNMP" before configuring the RMON alarm function.

Perform the tasks in Table 22 to configure RMON alarm function.
