Hi ,@LolleQ 

Thank you for posting on our Business forum.
 

To help us properly investigate your issue, could you please share the following details with us:

• Could you provide the full details of your specific network topology?
• Could you please give a detailed description of the issue you are encountering? Are you experiencing abnormal traffic display on your dashboard? For instance, based on the screenshot you shared, both wireless and wired traffic readings dropped to zero – is this the exact problem you are facing?
• Does your overall network deployment include any wireless devices?
• Did you make any configuration changes to your network around the time when the wired traffic dropped to zero?
• Could you let us know the type and software/firmware version of the controller you are using?

Thank you very much for your cooperation, and we will follow up promptly once we receive your reply.
