Triggers
The Trigger Facility can be used to automatically run specified command
scripts when particular triggers are activated. When a trigger is activated by an
event, global parameters and parameters specific to the event are passed to the
script that is run. For a full description of the Trigger Facility, see the Trigger
Facility chapter in the Rapier Switch Software Reference.
The switch can generate triggers to activate scripts when a fibre uplink port
loses or gains coherent light. To create or modify a switch trigger, use the
commands:
CREATE TRIGGER=trigger-id MODULE=SWITCH
EVENT={LIGHTOFF|LIGHTON} PORT=port [AFTER=hh:mm]
[BEFORE=hh:mm] [DATE=date|DAYS=day-list] [NAME=name]
[REPEAT={YES|NO|ONCE|FOREVER|count}] [SCRIPT=filename...]
[STATE={ENABLED|DISABLED}] [TEST={YES|NO|ON|OFF}]
SET TRIGGER=trigger-id PORTS={port-list|ALL} [AFTER=hh:mm]
[BEFORE=hh:mm] [DATE=date|DAYS=day-list] [NAME=name]
[REPEAT={YES|NO|ONCE|FOREVER|count}]
[TEST={YES|NO|ON|OFF}]
The following sections list the events that may be specified for the EVENT
parameter, the parameters that may be specified as module-specific-parameters,
and the arguments passed to the script activated by the trigger.
