HA SSO over WAN

[marstoyanoff]

Hi all,

Yesterday, I was asked a very interesting queistion. Can I configure HA over the WAN connection b/n our HQ and DR? Each location has a  WLC 5508. My first answer was NO based on the HA (AP SSO) Deployment Guide; however, I wanted bring this topic to the community and find if someone has any ideas of a better design to recomend. Flexconnect is an option but it has its on pros and cons.

Thank you,

MS

AP SSO isnt supported across a WAN as a physical connection is needed based on the deployment guide. You can still do traditional ap failover.

Thanks marstoyanoff for the information but I have some more queries

I have purchased the 1 license of 100 AP. So if I go for N+1 design then should I need to purchase separate license of 100 AP for secondary WLC.

Also how I able to create VLAN 2 connectivity over WAN.

George is correct on this. One thing you can do that is stable is using v7.4 and N+1 design. Thus does not perform AP SSO but is something you can implement if you have a HA sku WLC.
