Solved: Application Visibility issues

Karl Wilson · ‎04-13-2022

Hi Guys,

I have 2 switches that are showing CBAR related health issues that i don't know how to resolve.

Image attached, has anyone seen this before?

I have tried to reconfigure the switch\cbar but that doesn't do much at all

I think that first error explains all the rest. Without a valid certificate the switch can't establish the https session to give data to Cisco DNA. Try using the Actions->Telemetry->Update Telemetry Settings workflow in Inventory. Make sure to select "Force configuration Push" in the top of the popup. That will reconfigure the certificate on the switches.

Great! It occurred to me to put, in text, the error we are talking about so that google can find it and provide this advice to others:

"Device never communicated via HTTPS, threshold X minutes. Recommended to check that Cisco DNA Center certificate is installed on the device."
