Set Config Threshold command
Description Sets the port alarm threshold parameters by which the switch monitors port performance and
generates alarms. The changes you make with this command are not retained when you reset or
power cycle the switch unless you save them using the Config Save command.
Authority Admin session and a Config Edit session
Syntax
set config threshold
This command initiates a configuration session by which to generate and log alarms for selected
events. The system displays each event, its triggers, and sampling window one line at a time and
prompts you for a value. For each parameter, enter a new value or press Enter to accept the current
value shown in brackets. Table 24 describes the port alarm threshold parameters.
Table 24 Set Config Threshold parameters
Parameter Description
Threshold Monitoring Enabled Master enable/disable parameter for all events. Enables (True)
or disables (False) the generation of all enabled event alarms.
The default is False.
CRCErrorsMonitoringEnabled
DecodeErrorsMonitoringEnabled
ISLMonitoringEnabled
LoginMonitoringEnabled
LogoutMonitoringEnabled
LOSMonitoringEnabled
The event type enable/disable parameter. Enables (True) or
disables (False) the generation of alarms for each of the
following events:
• CRC errors
• Decode errors
• ISL connection count
• Device login errors
• Device logout errors
• Loss-of-signal errors
Rising Trigger The event count above which a rising trigger alarm is logged.
The switch will not generate another rising trigger alarm for
that event until the count descends below the falling trigger and
again exceeds the rising trigger.
Falling Trigger The event count below which a falling trigger alarm is logged.
The switch will not generate another falling trigger alarm for
that event until the count exceeds the rising trigger and
descends again below the falling trigger.
Sample Window The period of time in seconds in which to count events
Notes The switch will shut down a port if an alarm condition is not cleared within three consecutive
sampling windows (30 seconds). Reset the port to bring it back online. An alarm is cleared when the
threshold monitoring detects that the error rate has fallen below the falling trigger.
