I've just replaced an older 5508 with two new 5508 controllers that we wanted to run in redundancy mode. I've followed the directions here: to configure my units. at this time i have my management, and redundancy management IP addresses configured in the same vlan on both units, also the service port addresses are in the same vlan, and the virtual interface is the same on both units. I setup the mirrored reference in the redundancy global configuration for redundancy mgmt IP and Peer redundancy mgmt IP on both units. I have designated the primary and the secondary units. after doing all of this i connected (with a patch cable) the RP ports on both units. On either unit i enable the SSO option and get the following message:
"Please configure Redundancy Management VLAN before enabling redundancy"
Clicking OK on this disables the option and returns me to the redundancy global configuration page. I have searched all over and have been unable to find a working resolution for this problem. I'm not finding much reference to this at all actually.
Thanks in advance.
