I have been trying to set up WLC SSO between two 5508 units .
After completing all the necessary steps , when i try and enable SSO ( from GUI or from the Command line ) - i get an error mentioned below (command line version ) :
"Mandatory parameters to make redundancy are not configured.
Untagging of Management VLAN is not supported with redundancy. Please configure Management VLAN before enabling redundancy."
I realize this is a bug with 7.5 or 7.6 OS.
I looked up at the bug tracking tool and it seems this has been fixed after 8.0 .
I am running 8.0.121 on my controllers . Still seem to be present and preventing SSO from happening .
Any idea if its something that i am doing wrong - or is the bug still left unfixed ?
