Introduction
This chapter provides information about the Trigger facility on this switch. For specific

Chapter 76, Triggers Configuration . For detailed
descriptions of the commands used to configure triggers, see Chapter 77, Trigger
Commands .
Trigger Facility
The Trigger facility provides a powerful mechanism for automatic and timed management
of your device by automating the execution of commands in response to certain events.
For example, you can use triggers to deactivate a service during the weekends, or to
collect diagnostic information when the CPU usage is high.
A trigger is an ordered sequence of scripts that is executed when a certain event occurs. A
script is a sequence of commands stored as a plaintext file on a file subsystem accessible
to the device, such as Flash memory. Each trigger may reference multiple scripts and any
script may be used by any trigger. When an event activates a trigger, the trigger executes
the scripts associated with it in sequence. One script is executed completely before the
next script begins. Various types of triggers are supported, each activated in a different
way.
Configuring a Trigger
The following describes the general steps to configure a trigger. For specific configuration
examples, see
Chapter 76, Triggers Configuration .
Step 1: Create a configuration script
Create a configuration script with the commands you would like executed when the
trigger conditions are met. To create the configuration script using the CLI, use the
command:
Alternatively, you can create a script on a PC then load it onto your device using the
copy (URL) command.
Step 2: Enter the trigger configuration mode
You must be in the Global Configuration mode to reach the Trigger Configuration
mode. Use the command:
To create a trigger, and enter its configuration mode, use the command:
awplus# edit [<filename>]
awplus# configure terminal
awplus(config)# trigger <1-250>
