Registering and Defining an EEM Tcl Script
Perform this task to configure environment variables and register an EEM policy. EEM schedules and runs
policies on the basis of an event specification that is contained within the policy itself. When an EEM policy
is registered, the software examines the policy and registers it to be run when the specified event occurs.
Before You Begin
You must have a policy available that is written in the Tcl scripting language. Sample policies are provided--see
the details in the
Sample EEM Policies, on page 1782 to see which policies are available for the Cisco IOS
release image that you are using--and these sample policies are stored in the system policy directory.
