Hi,

can someone please explain how and where jumbo frames are generated. I know
that jumbo frames help increase throughput on gig links, but where and how are
these jumbo frames created. Surely there is no point in enabling jumbo frames
on ports, when there are no jumbo frames traversing the network in the first
place.

For example if an application is sending data across the network, does the
application have to generate jumbo frames, or can smaller frames be
consolidated into jumbo frames on the distribution and core switches and then
broken down into the small frames down at the access.. If so how do you
configure this.

Please can someone clearify..

Thanks in advance
