I installed FTDv 6.2.2 on ESXi and want to register it on FMC. But while I SSH to the FTDv, I always put in expert mode (admin@firepower:~$). I tried "exit" and "logout" command and even "CTRL+A then D" keys but all of them just logout me from the CLI and pressing Enter again put me in export mode, so I cannot use "configure manager add" command of FTDv. How can I exit from Expert mode on FTDv and enter to regular diagnostic CLI so being able to register it?
I search the net and found a method of disabling Expert mode completely. but I don't want to do that, because I run it on a lab for learning purpose and I might need it in the future.
