I set up VXLAN across 4 Nexus 9k - Most of the VXLAN traffic consists of video camera traffic. We notice that we can not access the cameras via HTTP and HTTPS across the VXLAN - We are able to get pass the loading page but video feed is not loading - Ping is working. We can access the cameras if we do not cross VXLAN.
- We enabled jumbo frame on uplinks of the N9k.
Has anyone else encountered this issue?

Your L3VNI SVI is configured with default MTU. Could you please set it to 9216.
