Hello,
Thank you. I now have more understandings on BE.
So, if the requirement said ensure web traffic have
300 kbps.........,
then I should use policy-map, right?
Also, I have seen examples that the policy-map is
applied under the
"map-class frame xxx" which is then applied under the
interface as "frame
class xxx". Is this the only way?
Could I apply the policy directly to the frame
interface?
By the way, in CBWFQ or LLQ, the bandwidth and the
priority command will take effect only when
congestion, right? So, if no congestion, the specified
traffic can use more bandwidth?
Thank you very much.
