Emre
Thanks for the reply. This is exactly what i was
looking for.
So as long as i follow the rationale of percentage.
my Total byte count for all the queues can be
anything.
I guess can it be 20000
then
www gets 50% or 10000
FTP/Telnet get 15 % or 3000
Fast0/0 gets 15% or 3000
Remaining traffic get 20 % 4000
Am i doing it correctly ???
thanks
