Class of Service
Class of Service support allows you to assign a higher priority to selected traffic passing through the switch. The switches support Class of Service attributes per the IEEE802.1D/D5 (previously known as IEEE 802.1p) standard specification using a priority queuing mechanism. This feature ensures that traffic during congestion periods will not interfere with traffic assigned a higher priority. Traffic assigned a lower priority is subject to discard when memory is in short supply. See Appendix D, “Class of Service,” for more information about this feature.
Application Examples
The exploding popularity of the Internet and of corporate intranets, as well as new,
The SW3322/SW3323/SW3324 switch is ideal for meeting the needs of today’s high performance networks. Their low cost and high port count make them affordable for dedicated 10/100Mb/s connections to the desktop. And their extensive features, including VLAN capability, provide the management needed for the workgroup and local backbone.
The following sections illustrate the switches employed in two examples:

Client/Server Network Application
To improve workstation performance in a client/server environment, the switches can be configured to provide 200 Mb/s full duplex Fast Ethernet connections to servers by connecting each to a dedicated switch port (Figure
