DNA Center and WLC 9800: Missing Netconf Port

[Bothwalker]

Hello,

i have problems connecting my DNA Center Version 2.1.2.6 to my WLC 9800 Version 17.3.3.

I configured Netconf Port 830 in the WLC and added the Port 830 in the DNA discovery.

I also checked via ssh if the port 830 is accessible. It worked.

However, if i try to connect the WLC to DNA, i get an error because of netconf: Missing Netconf Port

But when i look into my WLC log, i see:

May 11 15:55:04.725 MEST: %DMI-5-AUTH_PASSED: Chassis 2 R0/0: dmiauthd: User 'dna' authenticated successfully from x.x.x.x:37774 and was authorized for netconf over ssh. External groups: PRIV15

Does anyone have an idea what the problem is here?

Try re-discovering the 9800 and putting in the netconf port as part of the discovery.

tried to re-discover but found same issue.

My DNAC instance constantly had issues with Netconf on the 9800s. It would work, then one day it would stop working.

DNAC 2.2.3.3 seems to have cleared this up.

I have a mix of 17.3.3 or 17.3.4 on my controllers.
