Whether accessed from the console or by a Telnet session through a TTY port, a router can be placed in several modes. (see Figure) Each mode provides different functions: user EXEC mode -- This is a look-only mode in which the user can view some information about the router, but can change nothing. privileged EXEC mode -- This mode supports the debugging and testing commands, detailed examination of the router, manipulation of configuration files, and access to configuration modes. setup mode -- This mode presents an interactive prompted dialog at the console that helps the new user create a first-time basic configuration. global configuration mode -- This mode implements powerful one-line commands that perform simple configuration tasks. other configuration modes -- These modes provide more detailed multiple-line configurations. RXBOOT mode -- This is the maintenance mode that you can use, among other things, to recover from lost passwords.
