RMON C
OMMANDS
RMON ALARM
Default By default, there are no alarms.
Mode Global Configuration
Usage RMON alarms have a rising and falling threshold. Once the alarm monitoring is
operating, you cannot have a falling alarm unless there has been a rising alarm and
vice versa.
However, when you start RMON alarm monitoring, an alarm must be generated
without the other type of alarm having first been triggered. The
alarmstartup
parameter allows this. It is used to say whether RMON can generate a rising alarm
(
1
), a falling alarm (
2
) or either alarm (
3
) as the first alarm.
Note that the SNMP MIB Object Identifier (OID) indicated in the command syntax
with <
oid > must be specified as a dotted decimal value with the form
etherStatsEntry.< field>.<stats-index >, for example, etherStatsEntry.22.5.
Example To configure an alarm to monitor the change per minute in the etherStatsPkt value
for interface 22 (defined by stats-index 22 in the
rmon collection stats command),
to trigger event 2 (defined by the rmon event command) when it reaches the rising
threshold 400, and to trigger event 3 when it reaches the falling threshold 200, and
identify this alarm as belonging to Maria, use the commands:
awplus# configure terminal
awplus(config)# rmon alarm 229 etherStatsEntry.22.5 interval 60
delta rising-threshold 400 event 2 falling-threshold 200 event
3 alarmstartup 3 owner maria

The default is setting 3 (either).
