Usage Guidelines

If you want to allow the triggered event to process any default actions, you must configure the EEM policy to allow the default action. For example, if you match a CLI command in a match statement, you must add the event-default statement to the EEM policy or EEM does not allow the CLI command to execute. You can use the terminal event-manager bypass command to allow all EEM policies with CLI matches to execute the CLI command.
