Conventional Ethernet frames have a maximum size of about 1518 bytes. Jumbo Frames are special packets with size higher than 1518 bytes, often ranging into several thousands of bytes. Jumbo frames allow Ethernet systems to transfer large chunks of data in a single frame reducing the processor overhead and increasing bandwidth efficiency. DP83561-SP supports Jumbo frames up to 13 KB in 1000-Mbps and 100-Mbps speeds.
