Example: Combining CoS with MPLS on EX Series Switches on page 3188
Configure class of service (CoS) on your switch to manage traffic so that when the
network experiences congestion and delay, critical applications are protected. Using CoS,
you can divide traffic on your switch into classes and provide various levels of throughput
and packet loss. This is especially important for traffic that is sensitive to jitter and delay,
such as voice traffic.
This example shows how to configure CoS on a single EX Series switch in the network.
