Hi Team,

    I met a issue that the mobility tunnel can't be built between WLC3504 and WLC9800-40, their version meet the ICRM requirement, I suspect the issue happens since certificate using  by DTLS, I saw the logging information as follow:

Did you follow the guide on setting up the AireOS and 9800 mobility? There are settings you need to configure before the two can communicate. It’s not just setting up mobility.

Per the guide:

Note: On the 9800 WLC, control plane encryption is always enabled, which means that you need to have secure mobility enabled on the AireOS side.However, data link encryption is optional. If you enable it on the 9800 side, you will need to enable it on AireOS with config mobility group member data-dtls enable.

Yes, I have enabled the secure mobility tunnel and disable the data tunnel encryption, as follow:

[A screenshot of a cell phone Description automatically generated]
Above configuration should be right, I disable the data tunnel encryption in both sides.
