Chapter 10 Jumbo Configuration
10.1 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
discard the Jumbo frames sent to CPU in the packet receiving process.
