Have you ever found yourself navigating the complexities of Firepower Threat Defense, only to realize that troubleshooting an issue is a daunting task? Fear not, as there is still a way to access the old ASA CLI.
When you first SSH to an ASA running Threat Defense, you are greeted with the new CLI. However, by entering the command system support diagnostic-cli, you can unlock the hidden CLI.
Please note that there is a limitation: only one user can access the diagnostic CLI at a time. If someone else is already connected, you will need to wait for their session to end. Once you gain access, you will find yourself in enable mode, having already authenticated.
