Note
This is an optional step. Must defines is a section of the policy that tests whether
any EEM environment variables that are required by the policy are defined before
Program the must defines section to
check for each environment variable
that is used in this policy.
Step 5
the recovery actions are taken. The must defines section is not required if the
policy does not use any EEM environment variables. EEM environment variables
for EEM scripts are Tcl global variables that are defined external to the policy
before the policy is run. To define an EEM environment variable, use the EEM
configuration command event manager environment . By convention, all Cisco
EEM environment variables begin with "_" (an underscore). To avoid future
conflict, customers are urged not to define new variables that start with "_".
You can display the Embedded Event Manager environment variables
set on your system by using the show event manager environment
command in EXEC mode.
