Parameters
entry-number: Specifies an alarm entry index in the range of 1 to 65535.
alarm-variable: Alarm variable, a string of 1 to 256 characters. It can be in dotted object identifier (OID)
format (in the format of entry.integer.instance or leaf node name.instance, for example,
1.3.6.1.2.1.2.1.10.1), or a node name like ifInOctets.1. Only variables that can be parsed into INTEGER
(INTEGER, Counter, Gauge, or Time Ticks) in the ASN.1 can be used for the alarm-variable argument,
such as the instance of the leaf node (like etherStatsOctets, etherStatsPkts, etherStatsBroadcastPkts, and
so on) of the etherStatsEntry entry, the instance of the leaf node (like ifInOctets, ifInUcastPkts,
ifInNUcastPkts, and so on) of the ifEntry entry.
sampling-interval: Sets the sampling interval in the range of 5 to 65535 seconds.
absolute: Sets the sampling type to absolute. The system obtains the value of the variable when the
sampling time is reached.
delta: Sets the sampling type to delta. The system obtains the variation value of the variable during the
sampling interval when the sampling time is reached.
rising-threshold threshold-value1 event-entry1: Sets the rising threshold, where threshold-value1
represents the rising threshold in the range of –2147483648 to +2147483647, and event-entry1
represents the index of the event triggered when the rising threshold is reached. The value range for the
event-entry1 argument is 0 to 65535. If 0 is specified, the alarm does not trigger any event.
falling-threshold threshold-value2 event-entry2: Sets the falling threshold, where threshold-value2
represents the falling threshold in the range of –2147483648 to +2147483647 and event-entry2
represents the index of the event triggered when the falling threshold is reached. The value range for the
event-entry2 argument is 1 to 65535. If 0 is specified, the alarm does not trigger any event.
owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters that can contain
spaces.
Usage guidelines
You can create up to 60 alarm entries.
To make sure an alarm entry can take effect:
• Before creating an alarm entry, use the rmon event command to define the events to be referenced.
Otherwise, the alarm entry cannot trigger events, even if it can be created.
If the alarm variable is an instance of the leaf node of the Ethernet statistics table etherStatsEntry
•
with the OID of 1.3.6.1.2.1.16.1.1.1, use the rmon statistics command to create a statistics entry on the
monitored Ethernet interface. If the alarm variable is an instance of the leaf node of the history
record table etherHistoryEntry with the OID of 1.3.6.1.2.1.16.2.2.1, use the rmon history command
to create a history entry on the monitored Ethernet interface. Otherwise, the alarm entry cannot
trigger events, even if it can be created.
• Make sure the alarm entry has different alarm variable (alarm-variable), sampling interval
(sampling-interval), sampling type (absolute or delta), rising threshold (threshold-value1) and
falling threshold (threshold-value2) than any existing alarm entry in the system.
