WLC HA SSO configuration advice

[ammahend]

Hi community,

I have 2 X7510 controllers and both are managing some part of the wireless network, now we have planned to merge them into an HA SSO pair. below is how I am planning to do it, please advice if you have a better way.

current IPs on controller

controller 1 - X.X.Y.230, manages 900 APs

controller 2 - X.X.Y.231, manages 900 APs

Planned HA IPs

controller 1 - X.X.Y.230, manages 1800 APs (Primary)

controller 1 redundancy IP - X.X.Y.232

controller 2 - X.X.Y.231 (HA)

controller 2 redundancy IP - X.X.Y.233

Planned Steps

1. backup configs on both controllers.

2. shutdown controller 2 (All APs on controller 2 will automatically migrate on controller 1)

3. disable AP fallback on controller 1 (currently there is no primary or secondary configured on the APs so as soon as controller 2 comes back up APs will move back to controller 2)

4. configure redundancy IP, Peer IP, role as primary  on controller 1

5. connect back to back redundancy port

6. boot controller2, configure redundancy IP, Peer IP, role as secondary on controller 2

7. Enable AP SSO on both.

** both controllers are on same code and their are enough licenses**

looking forward to your response.

Hi

 Looks ok. What are you not sure about?

I was sure, but it doesn't hurt to take a second opinion from many experts on this forum, there is always a way to improvise, anyways everything went smooth. 

Thanks.

I'm not sure about your WLC model, but make sure the Primary WLC has those 1800 licenses. As far as I remember they don't add when doing HA-SSO.
