hi group.

I need help in CBWFQ case in the real world.
here it goes:

3 classes A,B,C the first is voice.

I have fast Ethernet interface and I need the limit it to 2M (that's what
the
customer wants to pay).
in 2M I have the police the traffic the A and B will get
0.5M each and C the other 1M.
Now for the problem: I want to be able the allocate the BW of class A if no
packets of voice are arriving and use it
in class B, the same case from B to C.
So, my config file have to give me the option to use the entire BW even if A
and B are empty. I've tried it in few ways (also with the new feature "two-
rate
policer" but no success.
The BW remaining commands cant help here because it define the way the
Allocate the left BW after the classes used the BW. My challenge is to "leak"
BW from class to class and not from the remaining "bank" to the classes

Experts, Any idea??

p.s the version can be 12.3...
