Sample EEM Policies

Cisco IOS XR Software contains some sample policies in the images that contain the EEM. Developers of
EEM policies may modify these policies by customizing the event for which the policy is to be run and the
options associated with logging and responding to the event. In addition, developers may select the actions
to be implemented when the policy runs.
The Cisco IOS XR Software includes a set of sample policies (see Sample EEM Policy Descriptions table).
The sample policies can be copied to a user directory and then modified. Tcl is currently the only scripting
language supported by Cisco for policy creation. Tcl policies can be modified using a text editor such as
Emacs. Policies must execute within a defined number of seconds of elapsed time, and the time variable can
be configured within a policy. The default is 20 seconds.
Sample EEM policies can be seen on the router using the CLI

Purpose
• Use the path argument to specify the absolute pathname
to the user directory.
Purpose
Displays the reliability metric data for processes. The system
keeps a record of when processes start and end, and this data
is used as the basis for reliability analysis.
