Command Reference RMON Commands
2 RMON Commands
2.1 rmon alarm
Use this command to monitor a MIB variable. Use the no form of this command to remove the
alarm entry.
rmon alarm number variable interval {absolute | delta } rising-threshold value [event-number]
falling-threshold value [event-number] [owner ownername]
no rmon alarm number
Alarm number. The value ranges from 1-65,535.
Alarm variable. The value is a character string consisting of 1 to 255
characters in OID dotted format (the format is entry.integer.instance or a
leaf node named .instance, for example. 1.3.6.1.2.1.2.1.10.1).
Sampling interval. The valye ranges from 1 to 2,147,483,647 in the unit of
second.
Absolute sampling. In this mode, when the sampling time arrives, the
system directly invokes the variable value.
Delta sampling. In this mode, when the sampling time arrives, the system
invokes the delta value of the variable within the sampling interval.
Rising threshold and the corresponding event number when the threshold is
reached. The threshold ranges from -2,147,483,648 to +2,147,483,647.
The event number ranges from 1 to 65,535.
Falling threshold and the corresponding event number when the threshold is
reached. The threshold ranges from -2,147,483,648 to +2,147,483,647
Owner of an entry. The value is a character string consisting of 1 to 63
characters that are case sensitive.
Global configuration mode.
The RGOS allows you to modify the configured history information of the Ethernet network,
including variable, absolute/delta, owner, rising-threshold/falling-threshold, and the
corresponding events. However, the modification does not take effect immediately until the
system triggers the monitoring event at the next time.
The example below monitors the MIB variable instance ifInNUcastPkts.6.
Ruijie(config)# rmon alarm 10 1.3.6.1.2.1.2.2.1.12.6 30 delta
