Au contraire, mon frere. The MAC SDU is simply a fancy architectural
term for the MAC payload, whether it be for a bridge function client, or
a Network layer protocol client.

Ethernet does not support source routed frames. Please see earlier
postings about obtaining appropriate reference material and
self-education.

Sir
my question is continued in transparent and source-routed frame

How the frame's nature is changed
means when a frame is said to be transparent frame and when a frame
is said to be source - routed frame

Is there any programming requirment for changing a frame either from
transparent to source - routed and vice - versa.
or the changing of frame is done automatically .....

Thanks

Vikrant

Again, you are looking at portions of the standard related to
internetworking between 802.5 Token Ring, FDDI, and Ethernet. Source
Routing was a bridging mechanism supported on 802.5 Token Ring and FDDI,
but is no longer used.

This topic (as well as most of the questions you have been raising
lately) is discussed in Chapter 3 and 6 of "The Switch Book". I strongly
suggest you obtain a copy and read it before throwing questions out
"into the aether" for others to educate you.
