Command Mode 
The management interface of Ruijie network devices falls into multiple modes. The command 
mode you are working with determines the commands you can use. 
To list the usable commands in each mode, enter a question mark (?) at the command prompt. 
After setting up a session connection to the network device management interface, you enter in 
the user EXEC mode first. In the user EXEC mode, only a few commands are usable with 
limited functions, for example, command show. The command results are also not saved. 
To use all commands, enter the privileged EXEC mode with the privileged password. Then you 
can use all privileged commands and enter the global configuration mode. 
Using  commands  in  a  configuration  mode  (for  instance,  global  configuration  or  interface 
configuration)  will  influence  the  current  configuration.  If  you  have  saved  the  configuration 
information, these commands will be saved and executed when the system restarts. To enter 
any of the configuration modes, first enter the global configuration mode. 
The following table lists the command modes, access methods, prompts, and exit methods. 
Suppose the equipment is named "Ruijie" by default.
