Most managed network devices have a command line interface that is accessible through telnet or ssh because it is powerful, flexible, and minimizes the resources required. I have attached version 3. Telnet or SSH for direct connections if the Telnet and SSH services are enabled in the selected Security Profile. This article is all about telnet configuration on Cisco switches. In this video, Todd Lammle demonstrates both Telnet and Secure Shell (SSH). Deny all other traffic and log the denied attempted connections. The Telnet is an old and non-secure application protocol for remote control services. This is done by usually saying privilege level 15 when setting up a user account on the router or switch.
