Secure Telnet Sessions

It's recommended to disable access through Telnet. However, if you do require Telnet and your management software provides a secure Telnet application, then use a secured Telnet connection (i.e., TLS). TLS protects Telnet traffic from network sniffing.

To secure Telnet:
1. Open the CLI Settings page (Setup menu > Administration tab > WEB & CLI folder > CLI Settings).
2. From the 'Enable Telnet Server' drop-down list, select Enable Secured:
