I do not understand why they assigned the dscp and scheduler-map to two different interfaces, can we assign both to the same interface.?

Apply the DSCP classifier (ezqos-dscp-classifier) to a Gigabit Ethernet interface (ge-0/0/0):

Apply the scheduler map (ezqos-voip-sched-maps) to a Gigabit Ethernet interface (ge-0/0/1):

Hi,

Yes you can configure classifiers and schedules to the same interface. The document may be showing the configuration with relation to the traffic flow.

ie.

packets on ingress (ge-0/0/0) are classified into the forwarding class

packets on egress (ge-0/0/1) are scheduled based on the scheduler-map

Got it, so they were just showing two options for traffic priority.

No reason to apply forwarding class and scheduler-map to the same interface, guess that could get ugly.

Thanks.

Hi,

In the context of the document it appears to be the traffic flow. But in practice you do want to classify and schedule on each interface.
