z
The entry-number must be globally unique and cannot be used on another interface; otherwise, the
operation fails.
z
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.
z
You can create up to 100 history entries for the device.
z
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 will be created. However, the validated
value of the buckets number argument corresponding to the entry is the history table size
supported by the device.
Configuring the RMON Alarm Function
Configuration Prerequisites
z
If you need to configure that the managed devices send traps 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.
z
If the alarm variable is the MIB variable defined in the history group or the Ethernet 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; otherwise, the creation of the alarm
entry fails, and no alarm event is triggered.
Configuration Procedure
Follow these steps to configure the RMON alarm function:

Create an event entry in the event
