WLC Redundancy

[naive.naive]

Hi,

I will be deploying 2 units of WLC4402, which run as active-passive (all the LAP will be registered to the primary WLC, the secondary WLC will only come up when the primary WLC fails).

Since I will be creating multiple VLAN to be associated to the WLAN(SSID) on both WLC,

1) May I know the VLAN IP address of the 2 WLC are the same or it must be different?

ANd we plan to have the LAP and WLC to be in the same subnet, does that means I will be running on Layer 2?

2) and if this is the case, I do not need DHCP option 45, right?

I'm new to the Unified wireless, and I can't seems to find the answer anywhere..or maybe I'm in the wrong URL..

Thanks in advance.

Hi Raj,

Your config and output makes me believe your mobility should work fine. Is your AP fallback not working?

Initial discovery of a controller is required for an AP to associate to a controller. After that, the AP learns the location of controllers within the mobility group. Maybe I was a little confusing there.

Thanks Dennis and Ankur... after restarting all the APs once again, it worked. i tested both the way, its working fine. Thank you for helping me.
