Guys, this "pause" frame does not appear to have anything whatsoever to do
with flow

Lab any more :- ), and HDLC
Lastly, the issue the original post raised - a switch.
In the reading of the this thread, and the reading of some of the
references, what I am determining is that if there is some kind of
flow control mechanism, it comes probably in the form of
of
'pause' frames . This is actually an annex to the
gigabit spec that defines a means of flow control by
using those pause frames . Like an send/no send
mechanisme . Certainly not all hardware in the Cisco
switches and available NIC's supports this mechanisme.

I believe what everybody is trying to reference is actually the
subspec contained in 802.3x, which is generally dealing with
Full Duplex transmission. An optional subcomponent deals with
flow control using "pause" frames. This appears in these links

It is gigabit ethernet but there are annex that
specify this kind of flow control . I would say that
gigabit ethernet is *only* relevant for trunk ports on
switches

There is one thing that confuses me about switches. If you have a switch
with a 100Mb port and 10Mb port and the 100 starts sending data to the 10
how does the sending station keep from overflowing the buffer on the switch
since there in now flow control at layer 2
As far as I know flow control is one of the functions of many data link
layer protocols, besides framing, error correction, sync and control.

It doesn't. Layer 2 device buffers full = packets dropped.
What should happen is that at the TCP level, the two end devices should
through the TCP flow control mechanisms, agree to a reduced transmission on
the part of the sender. UDP is another story - packets are bit-bucketed and
no one

This is true...sorry. I was reading a cisco document
on the Cat 6000s where they explained flow control as
being 802.3Z flow control. I screwed up...(see
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sft_6_1/configgd/ether.htm#xtocid170110)
Come to think of it...it's called

Come to think of it...it's called 802.1x
(http://www.ieee802.org/1/pages/802.1x.html). Cisco
supports it with some exceptions

Has to do with flow control.
If you say a device to pause , process the buffers and
then release the pause is indeed a minimal form of
flow control .
I never played with set port flowcontrol so I

Hi group
From Cisco Website, there are sample questions for CCIE Qualification Exam.
One of these questions is described below.
I couldn't understand when the answer says :
"Bridges cannot provide any form of flow control".
Flow control is a function of Network Layer.
Is this not
Both there are different kinds of flow control and they can operate at
Data-link Transport and Session layers all performing different kind of flow
control. In the context of that question the answer is dead on.
