recommended to split 100—which is interpreted as 100%—among all available source classes, e.g.
with 20, 30 and 50 as value for the respective share commands, which represent 20%, 30% and 50%.

15.8.2 Defining the Bit-Rate
The command
rate
is used with shaper link arbitration to assign the (average) bit-rate to the selected
source. When enough bandwidth is available each source will exactly receive this bandwidth (but
never more), when overloaded the shaper will behave like a wfq arbiter. Bit-rate specification for
shaper (kilobits)

15.8.3 Defining Absolute Priority
This command
priority
can only be applied to classes, but not to lower level polices. The class is
given absolute priority effectively bypassing the link arbiter. Care should be taken, as traffic of this
class may block all other traffic. The packets given “priority” are taken into account by the “rate-
limit”. Use the command
police
to control the amount of “priority” traffic.
