Explanation:

event cli match "zoneset *"
This defines the triggering event for the EEM applet. It detects any execution of a zoneset command and activates the applet.
action 1.0 puts "This Command May Cause Outages"
This prints the warning message to the terminal session. putsis used for displaying text output in EEM scripts.
action 2.0 cli command "enable"
This allows the zoneset command to be executed without blocking it. The EEM applet should not interfere with normal command execution, only alert the user.
