NOTE:
•
The
entry-number must be globally unique and cannot be used on another interface; otherwise, the
operation fails.
•
You can configure multiple history entries on one interface, but the values of the
entry-number
arguments must be different, and the values of the
sampling-interval arguments must be different too;
otherwise, the operation fails.
•
Up to 100 history entries can be created for the device.
•
When you create an entry in the history table, if the specified buckets
number argument exceeds the
history table size supported by the device, the entry is created. However, the validated value of the
buckets
number argument that corresponds to the entry is the history table size supported by the device.
Configuring the RMON alarm function
Configuration prerequisites
•
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 variable is the MIB variable defined in the history group or the Ethernet statistics group,
make sure that the RMON Ethernet statistics function or the RMON history statistics function is
configured on the monitored Ethernet interface; otherwise, the creation of the alarm entry fails, and
no alarm event is triggered.
