Hello,
I have question regarding N+1 redundancy with 2504-HA WLC.
Can I use 2504-HA unit for H+1 redundancy? SSO is not needed
I have two wireless network:
I plan to use two 2504-HA units for backups, one for network with WLC5508 and second for network with WLC2504.
In case N+1 redundancy is management with Prime mandatory ?
Solved! Go to Solution.

Hi,
Better to use same model and same software.
Case1: You have 5508WLC
Solution from my side: You must buy a another WLC with HA SKU license(Zero AP license). This wlc can work as N+1 and AP SSO as well as Client SSO but with higher version of code(7.5 or higher).
Case2: You have 2504 WLC
Solution: You must buy a another 2504 HA WLC: AIR-CT2504-HA-K9, that only supports N+1(No AP SSO and NO Client SSO)

Just to add.... since you have WLC's with different regulatory domains, you should by separate WLC's HA's for each. Can you use a 2504 HA wlc to backup a 5508 wlc... sure you can, I have a few customers who went that route because of cost... it will work, you just have to remember that there are features that a 5508 can do and the 2504 can't do, like QoS bandwidth limits, etc. This you will have to look and compare before you make a decision.
In the end, I would get an HA for the 5508 and a HA for the 2504.
Thanks,
Scott

Yes you can, but there are features that a 5508 can do that a 2504 can't do.... If this isn't a limitation to you, then you can use a 2504 HA to backup a 5508 WLC.

Yes, You can take another mode l for N+1. But as scott mentioned many feature will not be avilable with 2540 WLC, so its better to buy 5508. I know 2504 is cheaper but for future prospects 5500 series will be good.

Hello,
For the first Case, as i know from documentation, for N+1 redundancy it is not mandatory for HA model to be same, as primary ?
So can I take 2504-HA model for existing 5508 redundancy ?
