Bandwidth allocation 1

[AMBER12]

We have 7 Cisco 2620 routers connected in a ring topology through a Transfix 2 Mbits/s link.
Connected to each 2620 router is a Cisco 2950 switch

3 Vlans need to be created across this configuration.

Is it possible to configure for each Vlan a dedicated amount of bandwidth across the 2 Mbit/s link by QOS or other means and how can this be done please ?

For example:

access-list 101 permit ip 192.168.0.0 0.0.0.255 any
access-list 102 permit ip 192.168.1.0 0.0.0.255 any
access-list 103 permit ip 192.168.2.0 0.0.0.255 any
!
class-map VLAN10
match access-group 101
!
class-map VLAN20
match access-group 102
!
class-map VLAN30
match access-group 103
!
policy-map policy1
class VLAN10
bandwidth 512
queue-limit 30
class VLAN20
bandwidth 512
queue-limit 30
class VLAN30
bandwidth 1024
queue-limit 30
!
interface f0/0
service-policy output policy1
!

In this case during congestion, 512kbps outbound traffic is guaranteed for VLAN 10 and 20, and 1Mbps outbound traffic for VLAN 30.
