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:
