Telnet Runbook
A Telnet runbook sends commands over Telnet to legacy devices that do not support SSH, and shows the raw response on the result screen.
When to Use
Use Telnet only when the target device cannot be reached over SSH. Telnet transmits credentials and output in cleartext, so prefer SSH whenever the device supports it.
