Hi,
I think it should be like this:

a) Traffic from 1.1.1.0 at rate less than 10Mbps go through and anything
more will be dropped.
b) Traffic from 2.2.2.0 at rate less than 20Mbps ( i.e within contract) will
go through after getting precedence remarked to 5.
Traffic out of contract ie above 20M will be dropped.
c)Remaining traffic at rate less than 8 Mbps ( i,e within contract)
will go throught after remarked to precedence 5 and out of contract will be
dropped.

hope this helps
madhu

Hi Dave:

COMBINED
>any amount over is dropped.

Do you mean all users on 1.1.1.0 can only have combined 10M? Or each
individual user will have 10M?

tks
Alan
