When you log on to the system, the system is in operational mode
- Operational mode provides access to operational commands for showing and clearing information and enabling or disabling debugging, as well as commands for configuring terminal settings, loading and saving configuration, and restarting the system.
- Configuration provides access to commands for creating, modifying, deleting, committing and showing configuration information
Operation mode
vyatta@vyatta:~$ <Tab> vyatta@vyatta:~$ show <Tab> vyatta@vyatta:~$ show wan-load-balance status vyatta@vyatta:~$ show version vyatta@vyatta:~$ show configuration vyatta@vyatta:~$ show interfaces
Configure mode
To enter configuration mode type configure, to exit just type exit in operation mode
vyatta@vyatta:~$ configure [edit] vyatta@vyatta# In configuration mode we can also use show to view configure parameter vyatta@vyatta# show interfaces vyatta@vyatta# show load-balancing
When we finish our configuration, we have to commit the change before exit. For example: to Enable https Service.
vyatta@vyatta# set service https [edit] vyatta@vyatta# commit vyatta@vyatta# save vyatta@vyatta# exit
You will notice that which mode you are in by looking at the symbol $ (operation) or # (configure)
