CHAPTER 51
Priority Queue
51.1 Priority Queue Overview
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use this screen to configure the priority level-to-physical queue mapping. The
Switch has eight physical queues that you can map to the eight priority levels.
On the Switch, traffic assigned to higher index queues gets through faster while traffic in lower index
queues is dropped if the network is congested.
51.1.1 What You Can Do
Use the Priority Queue screen (Section 51.2 on page 369) to configure the priority level-to-physical
queue mapping.
51.2 Assign Priority Queue
Use this screen to assign priority level to each queue.
