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:
H Disabling Telnet access completely.
H Requiring a login for Telnet sessions that are not on the TS Management
Link.
H Assigning an access level for Telnet sessions.
H Disabling TS Management Link access.
