LevelOne FNS-5000B user manual Jumbo Frame Setting MTU

Jumbo Frame Setting (MTU)

"Jumbo frames" refer to Ethernet frames that are larger than 1500 bytes. It is designed to enhance Ethernet networking throughput and reduce the CPU utilization of large file transfers by enabling more efficient larger payloads per packet.

Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet that a given layer of a communications protocol can transmit.

FNS-5000B uses standard Ethernet frames: 1500 bytes by default. If your network appliances support jumbo frame setting, select the appropriate MTU value for your network environment. FNS-5000B supports 4074 and 7418 bytes for MTU.

Note: Jumbo frame setting is valid in Gigabit network environment only. Besides, all network appliances connected must enable jumbo frame and use the same MTU value.
