Quality of Service (QoS) Features

Some features that can affect QoS, such as ACLs and Voice VLAN, are

described in other sections within this chapter.

The QoS Differentiated Services (DiffServ) feature allows traffic to be

classified into streams and given certain QoS treatment in accordance with

defined per-hop behaviors. PowerConnect M6220, M6348, M8024, and

M8024-k switches support both IPv4 and IPv6 packet classification.

For information about configuring DiffServ, see "Configuring Differentiated

Services" on page 1125.

The Class Of Service (CoS) queueing feature lets you directly configure

certain aspects of switch queuing. This provides the desired QoS behavior for

different types of network traffic when the complexities of DiffServ are not

required. CoS queue characteristics, such as minimum guaranteed

bandwidth and transmission rate shaping, are configurable at the queue (or

port) level.

For information about configuring CoS, see "Configuring Class-of-Service" on

This feature provides ease of use for the user in setting up VoIP for IP phones

on a switch. This is accomplished by enabling a VoIP profile that a user can

select on a per port basis.
