3560 SRR sharing bandwidth

Hi Group,

I'm trying to clarify my understanding of 3560 SRR shaping and
sharing. If I have both configured, as per below:

Switch(config)# interface
gigabitethernet0/1
Switch(config-if)# srr-queue bandwidth shape 8 0 0 0
Switch(config-if)# srr-queue bandwidth share 4 4 4 4

Will queues 2,3 and 4 be
able to use bandwidth that is reserved for queue 1 if queue 1 doesn't need
it?

I understand that queue 1 will be guaranteed and limited to 1/8 of
1Gbps. But what will be the bandwidth available for 2, 3 and 4? Is it
4/(4+4+4) * interface speed (1Gbps). Or is it 4/(4+4+4) * remaining bandwidth
(1Gbps-125Mbps)?

Best regards,
Marcel
