[c-nsp] EEM applet for Vlan for switches

[amir agha]

Hi 
In routers for writing EEM applet through Cisco IOS Cli we normally use following command
event manager applet (name) trap
 
Does anyone has idea or suggestion that which command is used on Switches to write EEM applet through Cisco IOS Cli as the above mentioned command is not working on switches. What is the syntax??????
 
Any solid and concrete suggestion.?????????????????
