Re: 3560 qos egress queue

Hi there,

As far as i know this configuration will work as follows:
First Shaped mode will override shared mode for queue 1, which means that
queue 1 will be shaped to a maximum of 1/25 of interface bandwidth (1G in
our case) = 1/25 * 1G = 40 Mbps.
Then what happens is the following:
Remaining BW = Total Interface Bandwidth - Shaped Amount for queue 1 = 1 G -
40 Mbps = 960 Mbps
This amount will be divided among the three remaining queues according to
the weights 20/25/25.
Queue 2 will get : 20/65 * (Remaining)
Queue 3 will get : 25/65 *(Remaining)
Queue 4 will get : 25/65 * (Remaining)

This is far as i know.Please correct me if i am wrong.
