Management and Configuration Guide K/KA/KB.15.15

The RMON agent automatically runs in the switch. Use the RMON management station on your
network to enable or disable specific RMON traps and events. Note that you can access the
Ethernet statistics, Alarm, and Event groups from the HP Switch Manager network management
software. For more information on PCM+, see the HP Networking web site at
www.hp.com/networking
From the Products menu, select Network Management. Then click on PCM+ Network
Management under the HP Network Management bar.
The CLI supports the configuration of RMON alarm threshold settings. The settings can be saved
in the configuration file.
Syntax
[no] rmon alarm entry number alarm-variable sampling-interval absolute
| delta rising-threshold threshold-value1 falling-threshold2
threshold-value2 owner string
This command configures RMON sampling periods and threshold parameters. The no option
removes the alarm entry.
entry number <1-65535>: An alarm number that uniquely identifies the alarm threshold entry.
alarm-variable <object-string>: Object identifier of the particular variable to be sampled. Variables
must be of type Integer in order to be sampled.
sampling-interval <5-65535>: Time interval in seconds over which data is sampled and compared
with the rising-threshold and the falling-threshold.
absolute: The value of the selected variable is compared directly with the thresholds
at the end of the sampling interval.
NOTE: If the absolute option is used for alarm variables of counter-type, an RMON
trap is generated only once, when the threshold limit is reached. The RMON trap
is never generated again.
It is recommended that you use the delta option instead when using a counter-type
alarm variable.
delta: The value of the selected variable at the last sample is subtracted from the
current value, and the difference is compared with the thresholds.
rising-threshold <threshold-value1>:An integer value for the upper threshold for the sampled statistic.
A single event is generated when the current sampled value of the specified statistic becomes
greater than or equal to this threshold, and if the value at the last sampling intervals was less than
this threshold.
NOTE: The value of the rising-threshold must be greater than the value of the falling-threshold.
falling-threshold <threshold-value2>: An integer value for the lower threshold for the sampled
statistic. A single event is generated when the current sampled value of the specified statistic
becomes less than or equal to this threshold, and if the value at the last sampling interval was
greater than this threshold.
owner <string>: The name of the owner of this alarm.
