Telnet access can be limited by:
Disabling Telnet access completely.
Requiring a login for Telnet sessions that are not on the TS Access
Management Link.
Assigning an access level for Telnet sessions.

NOTE:
Regardless of a user’s login access level, a
user cannot operate at a level higher than the
access level specified for the Telnet session (e.g., if

has been set, the Level-1 user can only operate as
a Level-2 user).
If you are going to allow users to configure the unit,
keep the access at Level-1.
