I?m running two WLC 4402 with software version 18.104.22.168 which control 20 AIR-AP1242AG access points.
I configured on both WLCs the same mobility group and added the other WLC with IP and MAC address.
After that I configured every AP with a primary and secondary controller (sysName).
Fail-over and fall-back seem to work.
Is there any function that synchronizes the configuration of both controllers (e.g. WLANs, LocalNetUsers) and are there any useful commands (CLI) to check if the controllers "know" about the Mobility Group and the members?
If there is no syncronization of the configs and with WCS I can only push templates to the WLCs there is no way to create LocalNetUsers (via LobbyAdmin) that are known on all WLCs in the Mobility Group? Then I would have to use RADIUS for centralized Web-Auth which makes the LobbyAdmin role useless. Is that right or do I miss anything?
The output of the "show mobility summary" tells me which controllers are configured in the Mobility Group like on the Web-Interface. But it does not show "if it works", e.g. are the WLCs connected/associated. The Mobility Group feature is like a Black Box for me and I would like to see if and how it works...
Does anyone know other commands to have a deeper look on this functions?
I have two WLC 4402-12 running software version 22.214.171.124 in the same Mobility Group. The LWAPP transport mode is L3. Both WLCs are connected to the same subnets on the wired LAN; thus L2 inter-controller roaming.
All the APs are configured with a primary and secondary controller. AP Fallback is enabled on both WLCs.
When one of the WLCs is shutdown, its joined APs took around 40 seconds to successfully join to their secondary controller. When the original WLC is back online, the APs took around 20 seconds to fallback.
Is this normal? I understand the AP sends LWAPP heartbeat to its primary controller every 30 seconds. Is this timer tunable? Is it recommended to lower its value so as to speed up the failover of APs?

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
