Cisco DNA - WLC HA error

[AK002]

Hi Team,

With two Cisco WLC’s added to Cisco DNA, Both WLC’s read as reachable / Managed & compliant. But every time we configure them as a HA pair the WLC always displays as Non-Compliant within DNA. How can we make the HA configuration compliant.

Error message attached.

 - Check controller(s) versus DNA compatibility info's here :

                              Also pay attention to the required software versions mentioned per device

What WLC controller model and what Code it running.

[AK002]

Hello, 

Below are the versions. 

DNA System version 1.5.255 & Cisco WLC 9800-CL version 17.4.1.

After configuring HA from DNAC the WLC seems complilant for few minutes but after the compliance check it went on to the Non-Compilant state.

From WLC side HA config seems fine and HA formed sucessfully with all the config pushed by DNAC. 

Regards,
AK

The screenshot not help much to figure out what went wrong : ( you need to provide the WLC information on DNAC)

WLC # show wireless fabric summary   - give you some information.

look at the video may help you -

 Hello,

I followed the video already and Provisioned the HA from DNA to the WLC but it became Non-Compilant after few minutes.

vWLC#Show wireless fabric summary

Thank you for the input, Time for TAC and investigate and help you, under the hood of DNAC?

So I guess you decided to ignore @marce1000 advice?

Anyway you do need to check supported versions.  I don't see any mention of DNA Center 1.5.255 but the 2.1.2.5 release notes https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/2-1-2/release_notes/b_cisco_dna_center_rn_2_1_2.html#id_80742 show system module 1.5.255 so I guess you're using v2.1.2.5?

Anyway the compatibility spreadsheet @marce1000 pointed you to and https://www.cisco.com/c/dam/en/us/td/docs/Website/enterprise/sda_compatibility_matrix/index.html have the required info.  The latest supported (and recommended) version of IOS-XE on 9800 is 17.3.2a so 17.4.1 is not supported.  So you're on your own - unsupported means it's untested or they've tested it and can't support it because it's broken.

You should also refer to the open bugs in the release notes https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/2-1-2/release_notes/b_cisco_dna_center_rn_2_1_2.html#Cisco_Reference.dita_f84af2d3-e1d5-4891-a917-9098f7156907

If you're running a supported version and encounter a problem which isn't already a known bug then you'll need to open a TAC case, TAC will then raise a bug for it and it will (hopefully depending on severity) get fixed in a future release.  That's how these things work.  They're both new products evolving rapidly so you can always expect some bugs when using the latest releases.

1. Yes DNAC will be running using v2.1.2.5 version.
2. We have seen the same issue on version 16.12.4a & 17.3.2a of the WLC as well during our testing.

3. I could see a bug for 2.1.3 version but not sure they referes WLC HA or DNAC HA.

May be as you said this can be esclated to TAC due to the latest codes and releases.

Many thanks for your help.
