Configuring Variable Logic for EEM Applets

The Variable Logic for EEM Applets feature adds the ability to apply conditional logic within EEM applets.
Before variable logic is introduced, applets have a linear structure where each action is executed in the order
in which they are configured when the event is triggered. Conditional logic introduces a control structure that
can change the flow of actions within applets depending on conditional expressions. Each control structure
can contain a list of applet actions including looping and if/else actions which determine if the structure is
executed or not.
The information in applet configuration mode is presented as background to set the context for the action
commands.
To provide a consistent user interface between the Tool Command Language (Tcl) and the applet (CLI) based
EEM policies, the following criteria are followed:
• Event specification criteria are written in Tcl in the Tcl based implementation.
• Event specification data is written using the CLI applet submode configuration statements in the
Consolidated Platform Configuration Guide, Cisco IOS Release 15.2(4)E (Catalyst 2960-X Switches)

applet-based implementation.
Purpose
Generates an SNMP inform request when the EEM
applet is triggered.
• In this example, the inform request is generated
for the sysUpTime.0 variable.
Exits global configuration mode and returns to privileged
mode.
