The CBQ Class object which controls the allocation of bandwidth to
immediate children of AutoClasses. Each dynamically created child
will be allocated a maximum value of bandwidth specified
by xtmClassAutoClassChildMaxBwAlloc, as resources permit. For example,
if an AutoClass has a bandiwth allocation of 10M/s, and the
xtmClassAutoClassChildMaxBwAlloc should be greater than or equal to
10M/s if xtmClassAutoClassChildBounded is false(2).
