Hii, thanks for making this video. I need your help. currently, i have plan wireless deployment HA SSO on DC and DRC. WLC 1 on site A and WLC 2 on site B. Is possible we deploy HA SSO with different site ? Because RP need only L2 connectivity right ?

I have done all the configuration in one of my WLC 3504 and this one I am going to configure as the primary controller. The second one, what all the configuration to be needed before configuring the HA? If I configure the management IP details and activate the license, then the rest of the configuration will automatically replicate after doing the HA? or we have to do all the configuration in second WLC like the first device before configuring the HA?

Second WLC can be added any time, follow the steps for the secondary device. Make sure you have all the prerequisites are taken care like the Platform type and OS,etc... Once the HA SSO is formed the Primary WLC will push the config and licensing information to the secondary WLC as part of the Bulk sync.

You can always do scripting to do it, but if you are looking for one-time solution then go with Excel. Collect all ap names and use the auto fill in excel to create the CLI for changing the IP. Once you have the CLI for all APs, paste it in WLC CLI.

@@CiscoNetworking I guess I can use Excel since I already have everything in it and this is an ongoing task, we are working on a big size network reclamation stuff, do you have any basic info on WLC CLI command to change IP address of an specific AP name, then I have to figure out on how to automate (auto fill or script) it from Excel.
Configure a static IP address on the access point by entering this command: For IPv4-config ap static-ip enable Cisco_AP ip_address mask gateway For IPv6-config ap static-ip enable Cisco_AP ip_address prefix_length gateway

Hello, thanks for video... I did the same as You on our 3504s, but if I put command "sh int sum" at 10:32 than the command shows that both controller have same management IP addresses... if I do box failover (by using command redundancy force-switchover) to test HA than the standby unit become active ) and the "old active unit" starts rebooting but Im unable to reach new active unit via web browser and after once the old primary unit become alave it starts to be active also so both controllers looks active and Im unable to reach any GUI... in this case I can only reload the system with "reset system" commands on the "old primary unit" but both WLCs reloading automatically... and I have no idea why... any ideas? thaks a lot in advance... regards...

Looks like there is something wrong with the HA keepalive mechanism here. It can be because of the cable issue on the RP port. Please check the cabling and make sure there is nothing wrong on the communication side for Management and RP ports. If the HA keepalive mechanism is working as expected then the duel active state will not happen at any point of time

@@CiscoNetworking at this point the devices are connected to each other by using 30cm long patchcable... I rechecked the Cisco´s official article about SSO and found this "The new architecture for HA is for box-to-box redundancy. In other words, 1:1 where one WLC will be in an Active state and the second WLC will be in a Hot Standby state continuously monitoring the health of the Active WLC via a Redundant Port. Both the WLCs will share the same set of configurations including the IP address of the Management interface." so its ok that both WLCs have same management interface IP... I will test today out of office hours again to do force switchover and I will see what will happen... but I dont think that this is ok as after the reload the old primary unit bot WLCs seems to be primary unit... but thanks for reacting my comment here... I apreciate that...

When WLC runs on HA SSO both WLCs are going to share the same IP. Even though the IP is going to be the same the MAC address will change based on the active WLC MAC. So at any point of time we should not have both WLCs in an active state. This can happen only with a broken HA keepalive mechanism.

@@CiscoNetworking seems like that, but if I connect to management IP of primary-active unit as usual, I can see redundancy statistics under "Monitor/Redundancy/Statistics -> Category: All" and there are "Keepalive Couters"/"Network Latencies (RTT) for the Peer Reachability in microsec" etc and also I can see peer statistics under Monitor/Redundancy/Peer Statistics... under "Redundancy/Summary" I Can see that local state is active, peer state is "standby hot" redundancy state "SSO" "Bulk Sync status: complete"... so I think if there is no connection I wouldn´t see all their statistics...

Hi! I've got a question to you. Which ip address of controllers we should specify on DHCP server in field of 43 option, when SSO is enable, for initial AP deployment. Both ip address of conrollers managment ip - like in your tube lesson - 9.9.9.10 and 9.9.9.12 or just only one - 9.9.9.10 or something else?

After HA is established, the Secondary configuration will be overwritten by the Bulk Sync happens from the primary. After the bulk sync only one IP will be in action and that will be the Primary one. In our case 9.9.9.10 will be the active IP after HA SSO is established.

@@anihzahirah9877 Use the DHCP option 43 to give both WLC IPs so that APs will receive both WLC information with the DHCP Offer. Another option is to keep both the WLCs in to a Mobility Group so that all the APs in both of the WLCs will have the information about the second WLC in the Group. When even one of the WLC failed in a Mobility Group will allow the APs to Fall-Back to the next available WLC in the Mobility Group. Hope one of this method will serve your requirement.
