Chapter 9 Jumbo Configuration
9.1 Introduction to Jumbo
So far the Jumbo (Jumbo Frame) has not reach a determined standard in the industry (including the format
and length of the frame). Normally frames sized within 1519-9000 should be considered jumbo frame.
Networks with jumbo frames will increase the speed of the whole network by 2% to 5%. Technically the Jumbo
is just a lengthened frame sent and received by the switch. However considering the length of Jumbo frames,
they will not be sent to CPU. We discarded the Jumbo frames sent to CPU in the packet receiving process.
