3750 ME traffic shaping down stream traffic

I am trying to come up with the best way to traffic shape traffic with 3750 Me switches.  the traffic will be coming from a 6504 Sup-7203b downstream and going out the wan.  Core---L3---->6504--intvlan80--trunkport to--->3750Me---g/1/1/1-trunkport to---MetroE network--->int f0/0.80--branch router.  The idea is to use the 3750 to traffic shape the traffic going towards the wan/branch to 500 to match the contracted rate and then to use qos on shaped rate.  I tried to apply it to g1/1/1 using port based policies but it did not shape the traffic.  I changed everything to IP interfaces and it worked.  I need to break up the metroe into different vlans so I can bring branch offices in on different vlans.

Hi Jamie


cisoc 3750 Metro Series switches with the Hierarchical

Queuing Framework features on the Enhanced Service ports is

able to deliver traffic shaping, 2 rates 3 colors policers, and other

advance QoS features on its 8000 queues. With the set of rich

features and flexibility, the Service Providers will be able to

offers differentiated services to multiple customers serviced by a

Catalyst 3750 Metro Series switch.

3750 ME traffic shaping down stream traffic

Will traffic shaping with the vlan still work if the vlan interfaces are on the 6504 not the 3750me.  The 6504 will peer with the branch offices not the 3750me.  The traffic will traverse the 3750me and egress to the wan and hopefully it will shape the traffic.





Re: 3750 ME traffic shaping down stream traffic

Only the 3750ME can do shaping

Shape same to the example then u can shape per vlan on the wan edge 3750
