My questions are below the following example:
>
> class-map voice
> match access-group 101
> !
> class-map immediate-data
> match access-group 102
> !
> class-map priority-data
> match access-group 103
> !
> access-list 101 permit udp any any range 16384 32767
> access-list 102 permit ip any any precedence immediate
> access-list 103 permit ip any any precedence priority
> !
> policy-map mypolicy
> class voice
> priority 16
> class immediate-data
> bandwidth 32
> class priority-data
> bandwidth 16
> class class-default
> fair-queue 64
> queue-limit 20
> !
> map-class frame-relay fragment
> frame-relay cir 64000
> frame-relay mincir 64000
> frame-relay bc 640
> frame-relay fragment 50
> service-policy output mypolicy
