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 System
Volume 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 ]
Required
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 Refer to Table 1-1 for the parameters to be compared for different entries.
z
The system limits the total number of each type of entries (Refer to Table 1-1 for the detailed
numbers). When the total number of an entry reaches the maximum number of entries that can be
created, the creation fails.
