The class of service (CoS) can be used to groom classified packets to queues of different priorities on the egress port. The packets that are groomed to the queue of the highest priority are processed first. In this user interface, you can define the CoS type and CoS priority for each CoS ID, so that during flow configuration, you can define the CoS type and CoS priority of a flow by assigning a CoS ID to it.
In the NE Explorer, click the board and select . Click CoS Configuration tab.
