Cisco Tech Talk: Disable Weak Ciphers via CLI on C1200 and C1300 Switches
Securing remote access to your network devices is a fundamental requirement for any robust security strategy. In this episode of Cisco Tech Talk, we demonstrate how to view and fine-tune Secure Shell (SSH) encryption ciphers on your Cisco Catalyst 1200 and 1300 series switches using the Command Line Interface (CLI).
With the release of firmware version 4.1.7, you now have granular control over the encryption, host key, key-exchange (KEX), and message authentication code (MAC) algorithms supported by your switch. Whether you are aiming to meet strict compliance standards or simply want to disable older, less secure ciphers, this video provides the step-by-step guidance needed to strengthen your network’s defenses.
What You Will Learn in This Video:
-How to use CLI commands to view currently supported SSH algorithms and active sessions.
-The difference between configuring SSH ciphers for the switch as an SSH Server versus an SSH Client.
-How to manually select and restrict encryption, host key, KEX, and MAC algorithms to enhance security.
-The importance of choosing stronger, modern algorithms like GCM and RSA-SHA2.
-Best practices for verifying your configuration changes and understanding the implications of firmware downgrades.
