Entering and Exiting Configuration Mode

You configure the JUNOS software by entering configuration mode and creating a hierarchy of configuration mode statements.

• To enter configuration mode, use the configure command.

  When you enter configuration mode, the following configuration mode commands are available:

  user@host> configure

  entering configuration mode

  [edit]

  user@host# ?

  Possible completions:

  <[Enter]> Execute this commandactivate Remove the inactive tag from a statementannotate Annotate the statement with a commentcommit Commit current set of changescopy Copy a statementdeactivate Add the inactive tag to a statementdelete Delete a data elementedit Edit a sub-elementexit Exit from this levelhelp Provide help informationinsert Insert a new ordered data elementload Load configuration from an ASCII filequit Quit from this levelrename Rename a statementrollback Roll back database to last committed versionrun Run an operational-mode commandsave Save configuration to an ASCII fileset Set a parametershow Show a parameterstatus Display database user status top Exit to top level of configurationup Exit one level of configuration

  Users must have configure permission to view and use the configure command. When in configuration mode, a user can view and modify only those statements for which they have access privileges set. For more information, see the JUNOS System Basics Configuration Guide.

• If you enter configuration mode and another user is also in configuration mode, a message shows the user’s name and what part of the configuration the user is viewing or editing:

  user@host> configure

  Entering configuration mode

  Current configuration users:

  root terminal p3 (pid 1088) on since 1999-05-13 01:03:27 EDT

  [edit interfaces so-3/0/0 unit 0 family inet]

  The configuration has been changed but not committed

  [edit]

  user@host#

  Up to 32 users can be in configuration mode simultaneously, and they all can make changes to the configuration at the same time. For more information, see When Multiple Users Configure the Software.

• To exit configuration mode, use the exit configuration-mode configuration mode command from any level, or use the exit command from the top level. For example:

  [edit protocols ospf area 0.0.0.0 interface so-0/0/0]

  user@host# exit configuration-mode

  exiting configuration mode

  user@host>

  [edit]

  user@host# exit

  exiting configuration mode

  user@host>

  If you try to exit from configuration mode using the exit command and the configuration contains changes that have not been committed, you see a message and prompt:

  [edit]

  user@host# exit

  The configuration has been changed but not committed

  Exit with uncommitted changes? [yes,no] (yes) <Enter>

  Exiting configuration mode

  user@host>

• To exit with uncommitted changes without having to respond to a prompt, use the exit configuration-mode command. This command is useful when you are using scripts to perform remote configuration.

  [edit]

  user@host# exit configuration-mode

  The configuration has been changed but not committed

  Exiting configuration mode
