Replace Primary WLC in SSO Deployment.


I have 2 WLC's running in SSO mode, and I need to replace the Primary Box.

  • I have the Redundancy Ports directly connected with a Ethernet Cable
  • I made a backup of the Primary WLC.
  • And enabled SSO, with the same IP Addresses I have used on the Primary

As soon as the Primary reboot (after enabling SSO), it comes up, but does not "see" the neighbor, and after 120 sec go into Service Mode.


Any Ideas why it would not see the redundancy neigbor ?  or what to do ?
