Secure Shell (SSH) is the recommended protocol to securely manage Cisco switches remotely. This FAQ provides concise answers and essential steps to enable SSH on Cisco Catalyst switches, helping you protect your network devices from unauthorized access.

To configure SSH on a Cisco switch and enable secure remote management, you typically need to set up a local user account, configure an IP domain name, generate RSA cryptographic keys, specify the SSH protocol version, and apply these settings to the Virtual Teletype (VTY) lines. This process ensures encrypted communication, protecting sensitive management traffic from eavesdropping and unauthorized access, unlike older, insecure protocols like Telnet.
