how can we installe two AIR-WLC2125-K9 at the same network?

Hi,

I have one AIR-WLC2125-K9 installed and controll 25 APs,

Now i want to add some APs, so i have asked my supplier and he propose to add an other AIR-WLC2125-K9, i will have all APs contrlled by 2 x AIR-WLC2125-K9.

I want to know if it's possible???

How can i add the second controller to work with the first one???

Thanks.

Configure controller #2 identical to controller #1 (Same wlans [name/order], same AP-Groups, Same dynamic interfaces) and then all you really have to do is make them mobility aware of each other.

Controller > Mobility Management >   [add the mac address and IP to each other's wlc]

Honestly, if you just take a configuration backup of WLC#1,  change the hostname and ip addresses, and then load it to WLC#2, about the only thing you'll need to do is setup mobility.

Firstly, copy the config of WLC 1 into your TFTP server.  Edit the config files for the IP address.  Copy this config file into WLC 2.  Make sure the WLC 2 switch port is in the same VLAN as WLC 1.

Don't bother with redundancy because it won't work as both are already loaded.

If you want to do redundancy then I'd consider getting a pair of WLC5508 with 100 WAP license.
