Subject: CBWFQ Question
The following paragraphs are from CCO.
The sum of all bandwidth allocation on an interface cannot exceed 75 percent
of the total available
interface bandwidth. The remaining 25 percent is used for other overhead,
including Layer 2 overhead,
routing traffic, and best-effort traffic. Bandwidth for the CBWFQ
class-default class, for instance, is
taken from the remaining 25 percent.
If a default class is configured with the bandwidth policy-map class
configuration command, all
unclassified traffic is put into a single queue and given treatment
according to the configured bandwidth.
If I assign 30% of bandwidth to the default class using the bandwidth
command, that would leave 45% of bandwidth for the rest of the classes.
Since the remaining 25% is always guranteed for the default class, does that
mean the default class gets 55% of the total bandwidth ?
