If you want to allow the triggered event to process any default actions, you must configure the EEM policy
Note
to allow the default action. For example, if you match a CLI command in a match statement, you must
add the event-default action statement to the EEM policy or EEM will 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.
