rmon
Syntax rmon
Context config>system>thresholds
Description This command enables the context to configure generic RMON alarms and events.
Generic RMON alarms can be created on any SNMP object-ID that is valid for RMON
monitoring (for example, an integer-based datatype).
The configuration of an event controls the generation and notification of threshold crossing
events configured with the alarm command.

Context config>system>thresholds>rmon
Description The alarm command configures an entry in the RMON-MIB alarm table. The alarm command
controls the monitoring and triggering of threshold crossing events. In order for notification or
logging of a threshold crossing event to occur, there must be at least one associated
rmon>event configured.
The agent periodically takes statistical sample values from the MIB variable specified for
monitoring and compares them to thresholds that have been configured with the alarm
command. The alarm command configures the MIB variable to be monitored, the polling
period (interval), sampling type (absolute or delta value), and rising and falling threshold
parameters. If a sample has crossed a threshold value, the associated event is generated.
Use the no form of this command to remove an rmon-alarm-id from the configuration.
Parameters rmon-alarm-id — a numerical identifier for the alarm being configured. The number of
alarms that can be created is limited to 1200.
Values 1 to 65535
Default n/a
oid-string — the SNMP object identifier of the particular variable to be sampled. Only
SNMP variables that resolve to an ASN.1 primitive type of integer (integer, Integer32,
Counter32, Counter64, Gauge, or TimeTicks) may be sampled. The oid-string may
be expressed using either the dotted string notation or as object name plus dotted
instance identifier. For example, “1.3.6.1.2.1.2.2.1.10.184582144” or
“ifInOctets.184582144”.
