System view 

2: System level 

entry-number: Alarm entry index, in the range 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: Sampling interval, in the range 5 to 

65,535 seconds. 

absolute: Sets the sampling type to absolute, namely, the system obtains the value of the variable 

when the sampling time is reached. 

delta: Sets the sampling type to delta, namely, 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 –2,147,483,648 to +2,147,483,647, and event-entry1 

represents the index of the event triggered when the rising threshold is reached. event-entry1 ranges 

from 0 to 65,535, with 0 meaning no corresponding event is triggered and no event action is taken when 

an alarm is triggered. 

falling-threshold threshold-value2 event-entry2: Sets the falling threshold, where threshold-value2 

represents the falling threshold, in the range –2,147,483,648 to +2,147,483,647 and event-entry2 

represents the index of the event triggered when the falling threshold is reached. event-entry2 ranges 

from 1 to 65,535. 

owner text: Owner of the entry, a string of 1 to 127 characters. It is case sensitive and space is 

supported. 

Use the rmon alarm command to create an entry in the RMON alarm table. 

Use the undo rmon alarm command to remove a specified entry from the RMON alarm table. 

This command defines an alarm entry, so as to trigger the specified event when abnormity occurs. The 

event defines how to deal with the abnormity. 

The following is how the system handles alarm entries:
