Configuring the RMON Alarm Function
Configuration Prerequisites
z If you need to configure that the managed ACs send traps to the NMS when it triggers an alarm
event, you should configure the SNMP agent as described in SNMP 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.
Configuration Procedure
Follow these steps to configure the RMON alarm function:
To do… Use the command… Remarks
Enter system view system-view —
Create an event entry in
the event table
rmon event entry-number [ description string ] { log |
log-trap log-trapcommunity | none | trap trap-community }
[ owner text ]
Optional
Create an entry in the
alarm table
rmon alarm entry-number alarm-variable
sampling-interval { absolute | delta } rising-threshold
threshold-value1 event-entry1 falling-threshold
threshold-value2 event-entry2 [ owner text ]
Create an entry in the
private alarm table
rmon prialarm entry-number prialarm-formula
prialarm-des sampling-interval { absolute | changeratio |
delta } rising-threshold threshold-value1 event-entry1
falling-threshold threshold-value2 event-entry2
entrytype { forever | cycle cycle-period } [ owner text ]
Required
Use at least one
command.
z A new entry cannot be created if its parameters are identical with the corresponding parameters of
an existing entry. See Table 9-1 for the parameters to be compared for different entries.
z The system limits the total number of each type of entries (See Table 9-1 for the detailed numbers).
When the total number of an entry reaches the maximum number of entries that can be created,
the creation fails.

created
Event
Event description (description string), event type (log, trap,
logtrap or none) and community name (trap-community or
log-trapcommunity)
