HI @randy-reed ,In IOS XE 17.x, Password 6 encryption isn’t supported for user secrets anymore, which is why you’re seeing the "Invalid encryption type: 6" error. Cisco moved away from Password 6 in favor of more secure methods like type 9 (scrypt), ...

If your Cisco Catalyst 9200L 48PXG switch is stuck in ROMmon mode, it usually means the switch failed to load the IOS software during boot. This can happen due to a corrupt IOS image, missing boot variables, or hardware issues.
