Jumbo frame problem when using switch I have two GigE `cameras`. I use 4 frame per second for capturing. Each frame of first camera is 2.3MB. Each frame of second camera is 1.8MB. So in a second I use 4 * 4.1 = `16.4 MB = 131 Mb of bandwidth`. When I connect each of camera to a computer they work correctly while `jumbo frame` is enabled. When I use a `cisco` switch (SG110D-8) between my cameras and computer, cameras say that maximum packet frame is `1440`. What is the problem? I read data sheet of the switch. It supports jumbo frame. I note that because of `processing time`, it is recommended that to use jumbo frame (9K).

According to the data sheet the 110 series supports a fixed jumbo size of 9216 bytes.

However, jumbo frames are non-standard and there's no real guarantee that they work. Possibly the camera is simply failing to detect the switch's size. If you can't force the size on the cam or if you do and it doesn't work there's little you can do short of trying another switch.

As a solution to your problem, connect the computer with a dedicated NIC for each camera and you're good. Alternatively, get a 10G switch and a NIC for the computer.
