Description
Use this command to create RMON alarms. RMON alarms monitor the
values of SNMP objects and trigger events when the values of the
monitored objects cross specified thresholds. Here are the guidelines to
this command:
The switch supports up to eight alarms.
An alarm can designate just one RMON statistic.
An alarm can belong to just one port at a time.
The port of an alarm must have an RMON statistics group. You
must create the group before the alarm. For instructions, refer to
“Adding Statistics Groups” on page 1127 or “RMON COLLECTION
STATS” on page 1152.
The port of an alarm is specified indirectly in the command. You
use the STATS_ID parameter to specify the ID number of the
RMON statistics group you added to the port.
The command must include both rising and falling thresholds.
The rising and falling thresholds can have different events or the
same event. The events must already exist.
The OID parameter in the command specifies the OID of the MIB statistic
the alarm is to monitor. The MIB object must be specified by its OID
number. An alarm can have just one MIB object. Table 115 lists the
possible object names and OID numbers. (The STATS_ID variable is the
ID number of a statistics group through which the alarm monitors a port.)
