The purpose of Jumbo Frame is to increase the transmission rate for the packets coming from
LAN via enlarging data size.
MTU (Max Transmit Unit) determines the largest size of a packet. When a packet with large
size is transmitted through Vigor router, the router will cut it into several segments to
facilitate the transmission. It always takes a lot of time. To reduce the sending number of
times, wasted bandwidth and transmission time, use Jumbo Frame to enlarge the size of the
data and speed up the transmission rate for packets coming from LAN.
