| 6.2.1 | Using router configuration modes
The EXEC mode interprets the commands you type and carries out the corresponding operations. You must log into the router before you can enter an EXEC command. There are two EXEC modes. The EXEC commands available in user mode are a subset of the EXEC commands available in privileged mode. From privileged mode, you can also access global configuration mode and specific configuration modes, some of which are listed here: Interface Subinterface Controller Map-list Map-class Line Router IPX-router Route-map If you type exit, the router will back out one level, eventually allowing you to log out. In general, typing exit from one of the specific configuration modes will return you to global configuration mode. Pressing Ctrl-Z leaves configuration mode completely and returns the router to privileged EXEC mode.
