■

■

Local or remote configuration via Telnet.

■

Remote configuration through dialing with modem via the AUX port.

■

environments of user interface (language-mode) and the telnet command. 
The operation of saving configuration file is not allowed on this level of 
commands.

■

Monitoring level: Commands of this level, including the display command and 
the debugging command, are used to system maintenance, service fault 
diagnosis, etc. The operation of saving configuration file is not allowed on this 
level of commands.
