N+1 redundancy with 2504-HA

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:

  • 1.      With WLC 5508 with about 40 AP(1262), all them are A regulatory domain
  • 2.      With WLC 2504, with about 30 Mesh AP(1552), all of them are E regulatory domain

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 ?

N+1 redundancy with 2504-HA

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.

N+1 redundancy with 2504-HA

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 ?
