Configuring
This chapter describes how to configure quality of service (QoS) on your switch. With this feature, you
can provide preferential treatment to certain types of traffic. Without QoS, the switch offers best-effort
service to each packet, regardless of the packet contents or size. It transmits the packets without any
assurance of reliability, delay bounds, or throughput.
To use the features described in this chapter, you must have the enhanced software image installed on
your switch.
If you have the standard software image installed on your switch, you cannot configure some of the
features.
