Ok well I got that far (thanks to you). Here are some things I'm noticing...
On my 6700 under EPST the Security entries HDR AN AUTH Password and PPP Password both have this funky formatted string (the hex).
In my 6900, after I did the edits in this post (and puti n the HEX from 6700 for AAA), the SAME funky formatted string is showing and is showing as AAA Shared Secret under M.IP Default Profile. However, in the Security entries the string isn't showing in HDR AN AUTH Password and PPP Password like it was on the 6700 (both fields are just blank, with
my#@vzw3g.com as the usernames above both respective fields).
In fact on the 6700 the AAA Shared Secret and 6900 AAA Shared Secret the values are completely different. The only thing consistent is that the AAA Shared Secret on the 6900 matches up with the HDR AN AUTH Password and PPP Password fields under Security on the 6700.
Any clues?
