Chapter 3: Terminal Menu Operation and Structure
Security Levels
Each menu item on the configuration screens has an associated security level. The security level ranges from 0 (highest security level) to 5 (lowest security level). This level determines whether a Telnet session can access that menu item. The Telnet session is assigned a security level set by the user. Passwords can only be accessed as security level 0. The maintenance port is always at se- curity level 0.
The security levels are assigned as follows:
Level
0Access all parameters including passwords
1Access all parameters except passwords
2Access all parameters except passwords and authentication methods
3Access all parameters except passwords, authentication methods, and ISDN parameters
4Access only test and status menus
5Access status menus only
