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
0	Access all parameters including passwords
1	Access all parameters except passwords
2	Access all parameters except passwords and
	authentication methods
3	Access all parameters except passwords,
	authentication methods, and ISDN parameters
4	Access only test and status menus
5	Access status menus only
