EX2500 Ethernet Switch Configuration Guide

Queuing and Scheduling

The EX2500 switch has eight output Class of Service (COS) queues per port, into which each packet is placed. Each packet’s 802.1p priority determines its COS queue. Higher COS queue numbers provide forwarding precedence.

You can map 802.1p priority value to a COS queue, as follows:

ex2500(config)# qos transmit-queue mapping <802.1p priority value (0-7)> <COS queue (0-7)>
