QOS to manage outbound bandwidth to DSL

Setup:

Cisco Catalyst 2970G 28Port Gigabit Switch WS-C2970G-24TS-E

GigabitEthernet0/1 connected to DSL equipement connecting to the Internet

GigabitEthernet0/9 connected to the network that is to limit its equipments outbound Internet speed.

This is what I have configured so far:

access-list 101 deny   ip 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255

access-list 101 permit ip any any

mls qos srr-queue output dscp-map queue 2 threshold 1  38

this puts anything marked with DSCP decimal 38 into queue 2

policy-map intg09

  class intg0

   set ip dscp af43

this assigned to g0/9 sets traffic as per the ACL to be DSCP af43 (decimal 38)

interface GigabitEthernet0/9

service-policy input intg09

!

this shows the policy applied to the interface

interface GigabitEthernet0/1

srr-queue bandwidth share 10 1 1 1

priority-queue out

This gives queue 1 priority over everything and ten times more packets serviced than queues 2/3/4

Queue 1 would be everything other than traffic from Gi0/9

Queries:

Overall it does not appear to be working, as traffic from say Gi0/9 and Gi0/10 equally share the outbound bandwidth to the internet

It appears that any traffic from equipment on GigabitEthernet0/9 even if it is not destined for the Internet (GigabitEthernet0/1) is limiting its LAN speeds.

Something that might be related to the above, is that I am monitoring the Traffic on (GigabitEthernet0/1) via:

monitor session 1 source interface Gi0/1

monitor session 1 destination interface Gi0/3

but am seeing a lot of non Internet related traffic on Gi0/1, via its SPAN on Port 3.

ie/ Traffic from a Host on Gi0/15 to a Host on Gi0/16 or Hosts on Gi0/09(with the above QOS) to a Host on Gi0/16

Any ideas of my issues?

Regards,

Alby
