Traffic shaping / policing inbound traffic

I have a host with a 20mb mpls connection, with several remotes all with single T1 MPLS connections.

I have my interesting traffic being tagged with my desired DSCP values. (i can cofirm this with show policy-map int ...) Currently I'm only tagging my citrix traffic EF, AF41, AF42, 21, my management (ssh, telnet, tftp,) into 21 and allowing most everything else to fall into the default-class

The issue I am running into is from a remote site, if i download a file from my host it completely saturates my T1 and my traffic tagged EF or AF41 and AF42 suffers. My file transfer is being tagged as default-class. If i send the file out to my host, the shaping works as expected and my higher priority traffic isn't affected.

Most of the examples i've found are for two locaitons with the same speed, and traffic shaping seems like it would work much easier, but because my host has so much more bandwidth, it never even slows down. Is policing the correct thing to do at each remote, give my default class a very low CIR, but allow  BE to the full T1 bandwidth? Or is there something more graceful since this is a private MPLS connection

Thanks for the help!

Hello,

Sounds like you also need to apply some egress shaping/policing from the host towards the spokes.

I have attached a  good example from Ask the expert.

Creating a class-map for each location was the only other thing i could think of, i was just hoping there was a more elegant solution. Thanks for the example as well!
