Hi All,
I'm a bit unclear on the following quote from documentation CD. Does it mean
that my 4 classes can only have bandwidth added up to link bandwidth (256k in
this case), or should the 4 classes total to 75% of 256k? Or assume the 25%
will go to class-default?
Thanks,
Weihan

"You can configure class policies for as many classes as are defined on the
router, up to the maximum of 64. However, the total amount of bandwidth
allocated for all classes included in a policy map must not exceed 75 percent
of the available bandwidth on the interface. The other 25 percent is used for
control and routing traffic. (To override the 75 percent limitation, use the
max-reserved bandwidth command.) If not all of the bandwidth is allocated, the
remaining bandwidth is proportionally allocated among the classes, based on
their configured bandwidth."
