Registers the EEM policy to be run when the specified event
defined within the policy occurs.
In this example, the sample EEM policy named tm_cli_cmd.tcl is
registered as a system policy.
Configuring and Managing Embedded Event Manager Policies
• The all keyword displays all the EEM environment
variables.
• The environment-name argument displays information about
the specified environment variable.
• The var-name argument is the name assigned to the EEM
environment configuration variable.
• The var-value argument is the series of characters, including
embedded spaces, to be placed in the environment variable
var-name .
• By convention, the names of all environment variables
defined by Cisco begin with an underscore character to set
them apart; for example, _show_cmd.
• Spaces may be used in the var-value argument. The
command interprets everything after the var-name argument
to the end of the line to be part of the var-value argument.
• Use the system keyword to register a system policy defined
by Cisco.
• Use the user keyword to register a user-defined system
policy.
• Use the persist-time keyword to specify the length of time
the username authentication is valid.
