What is jumbo frame?

In computer networking, jumbo frames or jumbos are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard.[1] Conventionally, jumbo frames can carry up to 9000 bytes of payload, but variations exist and some care must be taken using the term. Many Gigabit Ethernet switches and Gigabit Ethernet network interface cards can support jumbo frames. Some Fast Ethernet switches and Fast Ethernet network interface cards can also support jumbo frames. (Wiki)
