need help to configure QoS

Hello,

I would like to configure the qos on a  brocade 2024F router, I proceeded as described in the manual as in the following example:

"In the example below, the DSCP 46 (Voice) is Assigned to high priority queue on ingress port and

goes out of Egress Port without changing the DSCP value in the packet.

Brocade (config) # int e 1/5

Brocade (config-if-e1000-1/5) # qos scheduler strict

Brocade (config-if-e1000-1/5) # int e 1/6

Brocade (config-if-e1000-1/6) # qos scheduler strict

Brocade (config-if-e1000-1/6) # int e 1/13

Brocade (config-if-e1000-1/13) # qos dscp encode-off policy

Brocade (config-if-e1000-1/13) # qos scheduler strict "

I applied the commands to my router interfaces but it does not seem to work . someone would have another solution or know why it does not work?

thank you

Re: need help to configure QoS

What are you seeing that leads you to believe QoS is not working?

Strict priority-based scheduling guarantees that higher-priority traffic is always serviced

before lower priority traffic. The disadvantage of strict priority-based scheduling is that lower-priority traffic can

be starved of any access.

Also, what version of firmware are you using?

Re: need help to configure QoS

hello,

I said that  because by testing with and without QoS I didn't see any difference.

I have limited the port bandwidth  to 200 kBytes / s, without downloading, the call goes well but  when downloading big files, the call was very bad.

Then I applied the QoS on the  router ports and repeating the tests I did not notice any improvement.

I do not remember which version of firmeware, but I know that it is a recent version.

someone can tell me if there is an other way to configure QoS on this router?

thanks.
