Security Levels
Each menu item on the configuration screens has an associated se-
curity 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 at se-
curity level 0. The maintenance port is always at security level 0.
The security levels are assigned as follows:
