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 is the wiser.

Subject: switch flow control
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?
