Switching

Hello,

I'm hoping someone can share some ideas on what might be causing this issue. I am trying to modify the configuration of an EX2200 switch to setup an aggregated link with 3 interfaces (ae0), which it's working fine. The only problem is that I cannot longer set any interface to a defined Schedulers for QoS.

When ever I try to add the following config:

class-of-service {
   interfaces {     
        ae0 {
            scheduler-map network-port-sched;
            unit * {
                classifiers {
                    dscp dscp_ba;
                }
                rewrite-rules {
                    dscp rewrite-dscp;
                }
            }
        }
    }
}


When I commit the changes, I get the following error:

               scheduler map "network-port-sched" has conflicts


The same occurs when I try to assign any custom Scheduler to any other interface.

I have attached a copy of the entire configuration.

Hello,

 I believe your problem is not related with schedulers configuration but to the fact that both control and voice are mapped to the same queue #7. (there should be a log message in 'messages' file, too).

 I'd move one class to a different number and try again.

 Cheers,

That was the problem!

Thank you!

I should've checked that before. I was using a bad cofig copy of a production switch.

Anyways, I'm posting the working config for anyone interested on setting up QoS.
