1.RMON statistics group configuration task list
TaskRemarks
Configuring a statistics entry
Required
You can create up to 100 statistics entries for 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.
2.RMON history group configuration task list
TaskRemarks
Configuring a history entry
Required
You can create up to 100 history entries for 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 the configurations identical and the creation fails.
Configuring the RMON alarm function
∙To enable the managed devices to send traps to the NMS when the NMS triggers an alarm event, configure the SNMP agent as described in the chapter “SNMP configuration” before configuring the RMON alarm function.
∙If the alarm variables that can be configured through the web interface are MIB variables defined in the history group or the statistics group, 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 1 to configure RMON alarm function.
