Controlling Telnet or FTP Access
The FrameSaver unit provides several methods for limiting access via a Telnet or
FTP session. Telnet or FTP access can be on a standard management link or on a
service provider’s troubleshooting (TS) management link.
Limiting Telnet Access
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.
Disabling TS Access Management Link access.
To limit Telnet access via a service provider’s troubleshooting management link,
see
Limiting Telnet or FTP Access Over the TS Access Management Link
on
page 6-8.

Assign an access level Session Access Level to Level-2 or Level-3.
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
a user has a Level-1 login and Level-2 telnet access
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.
