HDMI over Ethernet using VLAN configuration
HDMI over Ethernet using VLAN configuration
Good morning, I bought a HDMI over Ethernet extender that uses TCP/IP (similar to the ones in this link https://amzn.to/2D2VN91). Everything on the devices functions perfectly with no quality or signal issues. The main concern is that when connected and sending data, the network speed drops noticeably. With the devices plugged in, internet speeds fall to about 200mbps when fully connected, but drop to around 80mbps once they’re unplugged. On Speedtest.net, full speed is achieved when the devices are off, but with them on, speeds hover near 110mbps. I tried setting up a VLAN to isolate traffic and even enabled multicast, but the Auto Video-VLAN still didn’t improve performance. Is there something I’m overlooking, or are these results typical for this configuration? Thanks, Richard.
Issue arises because the device floods all ports since it lacks awareness of its counterparts, using a random approach. Adjusting your hub's switch settings: configure the two ports as untagged with their own VLAN (e.g., 200). Keep the remaining ports either tagged or untagged to prevent flooding. Note: For Netgear models, use port-based VLAN for those two ports.
I set up the VLAN just as you outlined, with two untagged ports on separate VLANs. The switch has no other VLAN configurations beyond the one I made. I’ll review my settings again just in case I overlooked something. If not, it looks like @mynameisjuan might be correct—multicast traffic could be overwhelming the switch, which would be a problem.
