Hello Folks,
For a long time i have tried to get Traffic Shaping work for my 500
Customer setup, but never succeded. I know i have made mistakes which i
ain't able to point out.
I have made a heirarchical setup where in the incoming-outgoing
bandwidth is split into 10 different subnets and i have filters to
divert traffic into these 10 different pipes. Then in each of these
pipes i then have all the clients under those subnets.
Below at the end i have attached the CBQ errors thrown when i
initialise the TC pipes.
Any help and pointers on the same will be appreciated.
Trevor
