Hello Community,

I hope you could help to me with the next issue,

I have 2 APs 3800E series and an one virtual WLC with IOS version 8.5.161.0

I will to try to signing the APs to vWLC but in the console port from the AP display me the follow messges:

[*08/16/2021 18:18:29.0003] CAPWAP State: DTLS Setup

[*08/16/2021 18:19:30.7878] Failed to join controller.

In the vWLC I found the DTLS section and I changed the diferent options, the options are:

dtls version: dtls_all, dtls1.0 and dtls1.2

dtls cipher suit: RSA-AES128-SHA, RSA-AES256-SHA, RSA-AES256-SHA256, ECDHE-ECDSA-AES128-GCM-

SHA256, and ECDHE-ECDSA-AES256-GCM-SHA384

But the problem pesist I mean the APs do not joining to the vWLC.

Could you guide me to solve this matters.

Thanks!

in your vWLC, under the interface with the IP of WLC-CIDESI_01' (ip: 10.10.10.101) did you check Enable dynamic AP management is ticked? If not you can enable it and try again. Since you meant is vWLC is believe it is AireOS, not the Catalyst. If it is Catalyst there is only one AP Manager interface and you must follow the below guide to make sure that you have created the certificate required for AP to WLC communication

wireless config vwlc-ssc key-size 2048 signature-algo sha256 password 0 <pwd>

Hello Community,

Thanks for you help!,

I justed solved this issue, I mean I changed the subnetwork in others words the original network it was vlan 200 there's no DHCP so I changed to vlan 210 with DHCP. The APs download information from the vWLC; I guess the new IOS for this APs and then I will return to the vlan 200 and assing the static IP address.

And finally the access points are signing without problem in the vWLC.

Thanks for you support!
