Hi Everyone,
I have tried to enable CoS using the ezqos config provided on the EX 4200 switch.
I did not want to use the groups as I like the configuration to be nicely layed out. Anyway, I copied the config in using the "load merge terminal" and all looked well.
I have also done the following:
set class-of-service interfaces ge-* scheduler-map ezqos-voip-sched-maps
set class-of-service interfaces ge-* unit * classifiers dscp ezqos-dscp-classifier
set class-of-service interfaces ge-* unit * rewrite-rules dscp default
My issue is that my new Polycom VVX 410 IP phone is not using the ezqos-voice-fc forwarding class.
Using a packet capture, I can see the DSCP vaule of 46 intering on ge-0/0/30 from the phone.
The forwarding class looks to be setup correctly with the un-touched config:
classifiers {
dscp ezqos-dscp-classifier {
import default;
forwarding-class ezqos-voice-fc {
loss-priority low code-points 101110;
}
forwarding-class ezqos-control-fc {
loss-priority low code-points [ 110000 011000 011010 111000 ];
}
forwarding-class ezqos-video-fc {
loss-priority low code-points 100010;
}
}
}
However, the traffic from the phone still seems to be landing in the Best Effort forwarding class.
I wondered if I am missing something or if the fact of 101110 being listed into the "dscp-default" classifier as well as the "ezqos-dscp-classifier" would cause a conflict as in the "dscp-default" classifier, it is added to the ezqos-best-effort forwarding class.
Also:
Switch1# run show class-of-service interface ge-0/0/30

Any help would be very appriciated, as I thought I understood this 😞
