Nested QOS; Router syntax to Switch syntax

Hi All,

I'm putting together a new QoS policy for a link and after I got it put together, i realized I was using syntax for a router, but I need to accomplish the below on a 4507R; SUP-IV switch.

Setup:

4507R connected via 55mbps MPLS WAN; IP address is placed on VLAN interface.

18x branches connecting to MPLS WAN via T1s

Goal:

Shape ALL traffic to 55mbps

Shape traffic to each individual branch to T1 speed

Of that T1 speed, carve out certain Bandwidth alottments for various traffic types. Line of Business App, VoIP, VoIP Control etc.

I came up with the below policy which uses nested QOS policies to achieve what I want (I think), but it's in the wrong syntax.

A. Can someone confirm that this policy will do what I am intending

B. How can I convert it to somthing I can configure on my 4507R. I can't seem to find any decent information regardin shaping other than shaping on the 4 outbound Tx-queues on the interface. I don't think doing that would accomplish what I want to do.

You are very limited on the 4500 switch unless you replace the SupIV with a Sup6E. Shaping isn't supported on your current hardware.

Ok Thanks, that's what I was afraid of. Can a 6500 with Sup-720 do this?

Yes, but you need WAN modules (SIP/SPA). It is not supported on regular LAN modules.
