Try assessing your understanding of Cisco's CBWFQ by looking at the following example: class-map match-all HTTP_R6 match access-group name HTTP_R6 ! policy-map CBWFQ class HTTP_R6 bandwidth remaining percent 5 ! interface Serial 0/1 bandwidth 128 clock rate 128000 service-policy output CBWFQ and answering a question on the imaginable scenario: Two TCP flows (think of them as HTTP file transfers) are going across Serial 0/1 interface. One of the flows matches the class HTTP_R6, and another flow,...
