I know there's quite a few posts on here about what you can and can't do with QoS on a SUP720 but we have a QoS template that I need to deploy (or advise on reconfiguration) for a customer that uses the Priorty command for Voice in the policy.
Taffic is marked at the Access layer in this network so the WAN router just looks at the DSCP markings and the policy just acts on them on the router WAN interface. This is fine when we use traditional WAN routers but in this case we've been asked to use 6500's with SUP720's and the Priority and Bandwidth commands are not supported outbound on the SUP720 gig interfaces.
Can anyone offer some advice on a workaround as we need to Voice placed in the Priority queue and ensure it's policed up to the same CAR as we subscribe to off the carrier at their PE router (in this case 30Mb).?
Here's my QoS policy and interface config. Would appreciated any help. Thanks.....John
