QoS on C3750G switch

QoS on C3750G switch
Hi,

We have a head office that connects to the branch offices. The branch offices connect to the head office for cirtix, internet, file sharing etc. One of the branch office is facing problem while accessing citrix from the head office. On monitoring the traffic, it was observed that internet traffic was congesting the bandwidth when users were trying to access citrix.

I do not have access to the branch or head office router as they are managed by service provider. However I was thinking of configuring QoS on the branch switch that connects to the branch router. Below is the configuration:

class-map CITRIX
match access-group name CITRIX
!
class-map OTHERAPPS
match access-group name OTHERAPPS
!
policy-map ControlCitrix
class CITRIX
bandwidth percent 40
class OTHERAPPS
bandwidth percent 60
!
ip access-list extended CITRIX
permit tcp any any eq 1494
ip access-list extended OTHERAPPS
permit ip any any
!

interface gigabitethernet 0/1
service-policy in ControlCitrix
I would like to know if it will be effective as configuring QoS on branch router.

PS:- the bandwidth command is not allowed under the policy-map.
