Re: Understanding Question - FRTS or MQC or Both

As always Garry, you are the man; above and beyond! Thanks.

Ok ... so the map-class is there to call out the service policy... check.

AND ... the service policy is nested to provide prioritization to traffic

This helps Garry, thanks for the example and links. Appreciate this.
