Configuring the RMON alarm function

Configuration prerequisites

Before you configure the RMON alarm function, complete the following tasks:
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 SNMP configuration in the Network Management and
Monitoring Configuration Guide.
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.

Configuration procedure

To configure the RMON alarm function:
To do...
1.
Enter system view.
2.
Create an event entry in the
event table.
3.
Create an entry in the alarm
table.
4.
Create an entry in the private
alarm table.
NOTE:
A new entry cannot be created if its parameters are identical with the parameters of an existing
entry. If the created entry is a history entry, it will only be compared with the existing history entries
on the same interface. See
The system limits the total number of each type of entries (See
When the total number of an entry reaches the maximum number of entries that can be created, the
creation fails.
Use the command...
