We have a network not unlike the one on the picture. It has 3 cisco 3550 switches with 5 subnets (one of them is voice vlan/subnet)

One of the switch ports on the 24-port switch is configured as a router port. The fibre gbics "trunks" between the switches. The others are "standard" switchports (some connecting to cisco sip phones with POE)

I want the following:
(example, just to make things "easy" to explain)

minimum 15% bw to vlan2 (192.168.2.0 0.0.0.255)
minimum 10% bw to vlan3 (192.168.3.0 0.0.0.255)
minimum 10% bw to vlan4 (192.168.4.0 0.0.0.255)
minimum 20% bw to vlan5 (192.168.5.0 0.0.0.255)
minimum 15% bw to vlan10 (voice) (192.168.10.0 0.0.0.255)

The bw over the trunks etc is not so important (for now). The important thing is bw to the ISP (4 Mbit/s)

How to configure this? I have looked at policy-maps with a certain percent of the bw of the interface etc.. But what if the "actual" bw is only 4 Mb/s ?

A complete example config would be GREAT!!
