I'm in the process of renewing my CCNA and figured I would go through the CCENT and CCNA videos as a quick refresher before sitting the exam. In watching the first few videos in the CCENT series, I noticed that on a couple occasions, when discussing the various password security methods, you mentioned that the 'enable password' password, the little-to-no encrypted password method, would still work if used in conjunction with the stronger 'enable secret' method. Basically, it was said that both would work. I do not believe this is the case.
Once you set the 'enable secret', it effectively disables the 'enable password' password from working any longer to grant priv-exec mode. I believe the only exception would be on very old versions of IOS (but that wouldn't really be relevant for the tests). The 'enable password' is only still present for backwards compatibility but will likely be phased out soon since no one really uses it anymore. This is why it warns you about setting the same password for both -- if you do, even though the 'enable password' won't actually work, it would allow someone to see what the valid 'enable secret' password is and gain access.
So basically, as long as you have the 'enable secret' set, which is what should be used, the 'enable password' can be anything else without concern -- though it should just be disabled.
Unless I'm missing something.
