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
in the Network Management and Monitoring Configuration Guide 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.
