question regarding queueing on Catalyst

Hi Group,

I have a question regarding queueing on the switches, for example on a 3560.
If I have a FastEthernet port and I enable srr-queueing as below:

mls qos
Int Fa0/15
  srr-queue bandwidth share 40 10 20 30

The configured values, reflect the percentage which the queue in case of
congestion is allocated. Which bandwidth value does the switch take to
calculate the real values? The Interface bandwidth, in our case 100Mb? If
I configure for example bandwidth 10, are the calculations based on 10Mb? So
the switch will start already start queueing (think that he is concested)
when traffic reaches 10Mb?

many thanks in advance

Roger
