[c-nsp] 7600 QOS Per Sub-interface

[ar]

  Hi.

I know 7600 QOS is PFC based.

But here's the setup.

1 GE interface has multiple sub-interfaces for different customers. Each sub-interface has to be assigned different bandwidth.
And that bandwidth has to be divided into voice, network management, critical data and Best effort.

Example, GigabitEthernet 1/9.100
               Sub-interface limit should be 10Mbps
                         - 60% priority for voice
                         - 5% remaining BW for Network management
                         - 20% remaining BW for critical date
                        - the rest will be for class-default

Another sub-interface will have a separate policy....

Is this achievable on 7600? If not, what will be the options using PFC-based QOS? wrr-queue seems to be applicable on the main interface only.


Need expert opinions.....


thanks
