Redirect Policy Commands
The shutdown command administratively downs an entity. Administratively downing an entity
changes the operational state of the entity to down.
Unlike other commands and parameters where the default state will not be indicated in the
configuration file, shutdown and no shutdown are always indicated in system generated
configuration files.
The no form of the command puts an entity into the administratively enabled state.
Default no shutdown
