[c-nsp] 3560 egress queue buffers

Is it possible to determine the number of buffers allocated to a 3560
egress queue?  The configuration guide tells us that buffer space can be
allocated among the 4 queues, using a queue-set, as follows:

mls qos queue-set output 1 buffers  A B C D

Were A, B, C and D are percentage values that must total 100.  My
question is "percentage of what number?"  The same question could be
asked about the Weighted Tail Drop thresholds.  Is it possible to
determine the absolute value of the buffer space allocated in packets or
bytes?

With the 3550 you can define buffer depth, in packets, using the reserve
levels, but I see no analog in the 3560.

Any input appreciated!
