Re: Need some guidance---QOS

Hi Anthony,

Thanks a lot for your inputs, the link provided is very useful. As suggested
I would use the MQC way to configure it.

I would make sure that I allocate some free bandwidth for the remaning
traffic as required.

thanks once again for your time & useful guidance.

Have a pleasant evening.

Regards

Sam
