3550 / Policy-Map QoS

Hello All -

I'm trying to limit available upload bandwidth on one of our Ethernet Customers off a 3550 switch running 12.2 .I recently tried applying a service-policy input to an interface, but it doesn't seem to limit the upload bandwidth.  I was able to limit the download with service-policy output on the vlan interface on our 6509 Router.  The customer is getting 7.5MB down and 68MB up. I'd like to lower it to 7.5 for the upload.

Any ideas?



Here is the quick config of the 3550 -

mls qos map cos-dscp 0 8 16 24 32 46 48 56

mls qos min-reserve 5 170

mls qos min-reserve 6 85

mls qos min-reserve 7 51

mls qos min-reserve 8 34

3550 / Policy-Map QoS

Have you tried applying 'service-policy output UPLOAD' to both your egress and ingress interfaces?

3550 / Policy-Map QoS

I applied the service policy output UPLOAD to the VLAN interface on the 6509.  This is helping rate limit the download on this customer's interface.
