Is it possible to use a 5500 WLC and a 2500 WLC as failover?

I am curious to know if there are any technical issues with this design. The 5500 WLC would be the primary and 2500 WLC would be the secondary. The only need for the secondary would be in the event of failure of the primary, and support needs when doing maintenance such as code upgrades.


We would use the same version of code on each controller and apply the necessary amount of AP licenses on each. The controllers would have identical configurations and host multiple SSID's, including offering guest services. Does the 2500 support guest network services?

Correct Answer by Stephen Rodriguez about 5 years 5 months ago

you could do that. The 2500 can do wireless guest, but not wired, and it can't be the anchor for a guest network.


How many AP are you going to have? The 2500 only goes up to 50.

Thanks for the fast response Stephen!


The 2500 would host no more than 25 AP's at a facility. For larger sites, I would deploy multiple 5500 WLC's. We intend to use 3600 series AP's globally.

Steve,


Isnt multicast handled differently on the 2500 vs the 5508 ?

Yeah, believe the 2500 only does multicast-multicast mode.  Which isn't that big of a deal usually.  MM being the preferred method.


the 2504 also has that 300M backplane limitation.  SO if you are going to use the 2504 I would recommend HREAP so you don't have to worry about that.


Not supported on 2504.

•Support for wired guest access.

•Cisco 2500 Series Controller cannot be configured as an auto anchor controller. However you can configure it as a foreign controller.

•Supports only multicast-multicast mode.

•Bandwidth Contract feature is unsupported.

•Access points plugged directly into the WLC.

•Service port support

•Apple Talk Bridging

•LAG

•Wired Guest
