    Using qos map shape command to throttle traffic?

    voicetech00 New Member

      I am attempting to throttle traffic over an MPLS network from one main office to several smaller remote offices. The main office has a 10 Mbps Metro E connection while all but one of the remote sites are connected to the MPLS networks via T1's. I already have a qos map in place to protect and mark voice traffic along with traffic shaping in place on the WAN interface for 10 Mbps. My proposed configuration change is adding a line to the qos map already in place and using the shape average command to hopefully throttle traffic to 1 Mbps to each site that is connected with a T1. Within that line i have a match command referencing an ACL that permits traffic from the main office to each remote office. We believe some remote offices are being sent too much traffic at once and voice packets are being dropped or delayed despite QoS in place. Can anyone review this config and please let me know if you believe this will accomplish my goal?
