Chapter 7 Menus
a) A jumbo frame is a frame larger than the maximum 1514 bytes (not
including FCS) of the standard Ethernet frame. Jumbo frames make it
possible to deliver larger payloads per packet. Since fewer packets need to
be routed, packet processing overhead is lower and network throughput is
potentially improved. (Note that this item is enabled only when LINK
SPEED is set to “1000Mbps”. For it to work, all other devices that handle
packets on the network must also support jumbo frames.)
