Hi,

use 7.4.121.0

after you do the upgrade, do the testing with 2 console cables on both units.

I agree go to version 7.4.121.0 I has some strange issues on prior releases. Personally I am running 7.6.120.0 right now but that's mainly due to support for the 3702 access points.

that's a good guide just to double check yourself just in case. -

Hi,

This is  bug with 7.4.100.0 version:

Check here: https://tools.cisco.com/bugsearch/bug/CSCue17421

You must upgrade to 7.4.121.0, its pretty stable version and then try again.
