Hi Diment,
Thanks a lot.
i have some more question.
What is the difference among traffic-shape rate in frame-relay main
interface, frame-relay traffic-rate and frame-relay cir ,bc,be etc. in
map-class frame-relay beda.
what is the difference when i put custom-queue-list in frame-relay main
interface and in map-class frame-relay beda.
when i should use cbwfq and when custom queue for 50% bandwidth for certain
trafic.
Thanks again.
I see your fundamental is very clear. you are great.
