+
+
+Confirm
+^^^^^^^
+
+The ``confirm`` command confirms the prior ``commit-confirm``.
+
+Comment
+^^^^^^^
+
+The ``comment`` commands allow you to insert a comment above the current configuration section.
+The command cannot be used at the top of the configuration hierarchy, only on subsections. Comments needs to be commited, just like other config changes.
+
+To add a comment to a section, while being already at the proper section level:
+
+.. code-block:: sh
+
+  [edit <section>]
+  vyos@vyos# comment "Type Comment Here"
+
+To add a comment directly to a section, from the top or a higher section:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# comment <section> "Type Comment Here"
+
+To remove a comment, add a blank comment to overwrite:
+
+.. code-block:: sh
+
+  [edit <section>]
+  vyos@vyos# comment ""
+
+Examples
+********
+
+To add a comment to the "interfaces" section:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# edit interfaces
+  [edit interfaces]
+  vyos@vyos# comment "Here is a comment"
+  [edit interfaces]
+  vyos@vyos# commit
+
+The comment would then appear like this:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# show
+   /* Here is a comment */
+    interfaces {
+        ethernet eth0 {
+    [...]
+
+
+An important thing to note is that since the comment is added on top of the section, it will not appear if the ``show <section>`` command is used. With the above example, the ``show interfaces`` command would return starting after the "interfaces {" line, hiding the comment:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# show interfaces
+   ethernet eth0 {
+  [...]
+
+
+To add a comment to the interfaces section from the top:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# comment interfaces "test"
+
+
+The comment can be added to any node that already exists, even if it's multiple levels lower:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# comment interfaces ethernet eth0 vif 222 address "Far down comment"
+
+
+Commit
+^^^^^^
+
+The ``commit`` command commits the proposed changes to the configuration file.
+Every changes done in the configuration session is only applied when the configuration is committed. To view the changes that will be applied, use the show command.
+To discard the changes without committing, use the ``discard`` command. The ``commit`` command doesn't save the configuration, you need to manually use the ``save`` command.
+
+The confirm keyword can be added, see ``commit-confirm``. A comment can be entered, it will appear in the commit log.
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# commit
+  Possible completions:
+    <Enter>       Commit working configuration
+    comment       Comment for commit log
+
+Commit-confirm
+^^^^^^^^^^^^^^
+
+The ``commit-confirm`` command commits the proposed changes to the configuration file and starts a timer.
+If the ``confirm`` command is not entered before the timer expiration, the configuration will be rolled back and VyOS will reboot.
+The default timer value is 10 minutes, but a custom value can be entered.
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# commit-confirm
+  Possible completions:
+    <Enter>       Commit, rollback/reboot in 10 minutes if no confirm
+    <N>           Commit, rollback/reboot in N minutes if no confirm
+    comment       Comment for commit log
+
+
+Compare
+^^^^^^^
+
+VyOS maintains backups of previous configurations. To compare configuration revisions in configuration mode, use the compare command:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# compare
+  Possible completions:
+    <Enter>	Compare working & active configurations
+    saved		Compare working & saved configurations
+    <N>		Compare working with revision N
+    <N> <M>	Compare revision N with M
+

+
+
+Copy
+^^^^
+
+The ``copy`` command allows you to copy a configuration object.
+
+Copy the configuration entrys from a firewall name WAN rule 1 to rule 2.
+
+.. code-block:: sh
+
+  [edit firewall name WAN]
+  vyos@vyos# show
+   rule 1 {
+       action accept
+       source {
+           address 10.1.0.0/24
+       }
+   }
+  [edit firewall name WAN]
+  vyos@vyos# copy rule 1 to rule 2
+  [edit firewall name WAN]
+  vyos@vyos# show
+   rule 1 {
+       action accept
+       source {
+           address 10.1.0.0/24
+       }
+   }
+  +rule 2 {
+  +    action accept
+  +    source {
+  +        address 10.1.0.0/24
+  +    }
+  +}
+
+Delete
+^^^^^^
+
+The ``delte`` command is to delete a configuration entry.
+
+This Example delete the hole ``service tftp-server`` section.
+
+.. code-block:: sh
+
+  delete service tftp-server
+
+Discard
+^^^^^^^
+
+The ``discard`` command removes all pending configuration changes.
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# discard
+  
+    Changes have been discarded
+
+Edit
+^^^^
+
+The ``edit`` command allows you to navigate down into the configuration tree.
+To get back to an upper level, use the ``up`` command or use the ``top`` command to get back to the upper most level.
+The ``[edit]`` text displays where the user is located in the configuration tree.
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# edit interfaces
+  [edit interfaces]
+  vyos@vyos# edit ethernet eth0
+  [edit interfaces ethernet eth0]
+
+Exit
+^^^^
+
+The ``exit`` command exits the current configuration mode. If the current configuration level isn't the top-most, then the configuration level is put back to the top-most level.
+If the configuration level is at the top-most level, then it exits the configuration mode and returns to operational mode.
+The ``exit`` command cannot be used if uncommitted changes exists in the configuration file. To exit with uncommitted changes, you either need to use the ``exit discard`` command or you need to commit the changes before exiting.
+The ``exit`` command doesn't save the configuration, only the ``save`` command does. A warning will be given when exiting with unsaved changes. Using the ``exit`` command in operational mode will logout the session.
+
+
+Exiting from a configuration level:
+
+
+.. code-block:: sh
+
+  [edit interfaces ethernet eth0]
+  vyos@vyos# exit
+  [edit]
+  vyos@vyos#
+
+Exiting from configuration mode:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# exit
+  exit
+  vyos@vyos:~$
+
+Exiting from operational mode:
+
+.. code-block:: sh
+
+  vyos@vyos:~$ exit
+  logout
+
+Error message when trying to exit with uncommitted changes:
+
+.. code-block:: sh
+
+  vyos@vyos# exit
+  Cannot exit: configuration modified.
+  Use 'exit discard' to discard the changes and exit.
+  [edit]
+  vyos@vyos#
+
+
+Warning message when exiting with unsaved changes:
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# exit
+  Warning: configuration changes have not been saved.
+  exit
+  vyos@vyos:~$
+
+Load
+^^^^
+
+The ``load`` command load a configuration from a local or remote file. You have to be use ``commit`` to make the change active
+
+.. code-block:: sh
+
+  <Enter>				Load from system config file
+  <file>				Load from file on local machine
+  scp://<user>:<passwd>@<host>/<file>	Load from file on remote machine
+  sftp://<user>:<passwd>@<host>/<file>	Load from file on remote machine

+
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# load
+  Loading configuration from '/config/config.boot'...
+
+  Load complete.  Use 'commit' to make changes active.
+
+
+Loadkey
+^^^^^^^^
+
+Copies the content of a public key to the ~/.ssh/authorized_keys file.
+
+.. code-block:: sh
+
+  loadkey <username> [tab]
+
+  <file>                      Load from file on local machine
+  scp://<user>@<host>/<file>  Load from file on remote machine
+  sftp://<user>@<host>/<file> Load from file on remote machine
+  ftp://<user>@<host>/<file>  Load from file on remote machine
+  http://<host>/<file>        Load from file on remote machine
+  tftp://<host>/<file>        Load from file on remote machine
+
+Merge
+^^^^^
+
+The ``merge`` command merge the config from a local or remote file with the running config.
+
+In the example below exist a ``default-firewall.config`` file with some common firewall rules you saved earlier.
+
+.. code-block:: sh
+
+  [edit]
+  vyos@vyos# show firewall
+  Configuration under specified path is empty
+  [edit]
+  vyos@vyos# merge default-firewall.config
+  Loading configuration from '/config/default-firewall.config'...

+  +        action accept
+  +        source {
+  +            address 10.1.0.0/24
+  +        }
+  ......
+
+
+Rename
+^^^^^^
+
+The ``rename`` command allows you to rename or move a configuration object.
+
+See here how to move the configuration entrys from vlanid 3 to 2
+
+.. code-block:: sh
+
+  [edit interfaces ethernet eth1]
+  vyos@vyos# show
+   duplex auto
+   hw-id 08:00:27:81:c6:59
+   smp-affinity auto
+   speed auto
+   vif 3 {
+       address 10.4.4.4/32

+  +}
+  -vif 3 {
+  -    address 10.4.4.4/32
+  -}
+  [edit interfaces ethernet eth1]
+  vyos@vyos#
+
+
+Rollback
+^^^^^^^^
+
+You can ``rollback`` configuration using the rollback command, however this command will currently trigger a system reboot.
+Use the compare command to verify the configuration you want to rollback to.
+
+.. code-block:: sh
+
+  vyos@vyos# compare 1
+  [edit system]
+  >host-name vyos-1
+  [edit]
+  vyos@vyos# rollback 1
+  Proceed with reboot? [confirm][y]
+  
+  Broadcast message from root@vyos-1 (pts/0) (Tue Dec 17 21:07:45 2018):

+  [edit]
+  vyos@vyos#
+
+Run
+^^^
+
+The ``run`` command allows you to execute any operational mode commands without exiting the configuration session.
+
+.. code-block:: sh

+
+
+Save
+^^^^
+
+The ``save`` command saves the current configuration to non-volatile storage. VyOS also supports saving and loading configuration remotely using SCP, FTP, or TFTP.
+
+.. code-block:: sh
+
+  <Enter>				Save to system config file
+  <file>				Save to file on local machine
+  scp://<user>:<passwd>@<host>/<file>	Save to file on remote machine
+  sftp://<user>:<passwd>@<host>/<file>	Save to file on remote machine
