There are two modes of operation in the command interface, enabled and normal modes. The enable and disable commands are used to enter and exit the system's enabled mode.
enableAll operations that do not modify the system configuration or display critical (security related) information are permitted in normal mode. In normal mode, the command prompt ends in a ">."
The enable command will prompt for the password, and if successful, the user will be in enabled mode. The command prompt for enabled mode ends with a "#" to indicate that configurations can be modified. To exit enabled mode, use the disable command.
Modified configurations are kept in an edit buffer and will not affect the runtime operation of the router. An enabled session may be terminated or timed out by the system if no user input occurs within 5 minutes. In this case, if a modified configuration buffer exists, it will remain in the system's memory until the system is restarted.
Show commands that display configuration information will display the edited copy while in enabled mode. It is possible to display the currently configured values (stored in non-volatile Flash ROM) by leaving enabled mode and reentering the show command.
If a configuration in the edit buffer has been modified, the command prompt will be preceded by a "*." This occurs whether in enabled mode or not.
The following example shows the enabling of enabled mode. Notice the prompt change after enabling.
Main RISC Router> enable Enter Password: password entered here Main RISC Router#
The following example shows a configuration session in which the system information is displayed, the domain changed, and then both the edited copy and the flash version is displayed.
