Chapter 2 Campus <strong>QoS</strong> <strong>Design</strong><br />

Catalyst 4500 Supervisor II+/III/IV/V—<strong>QoS</strong> Considerations and<br />

<strong>Design</strong><br />

This section includes the following topics:<br />

Catalyst 4500—Trusted Endpoint Model<br />

Catalyst 4500—Auto <strong>QoS</strong> VoIP Model<br />

Catalyst 4500—Untrusted PC + SoftPhone with Scavenger-Class <strong>QoS</strong> Model<br />

Catalyst 4500—Untrusted Server with Scavenger-Class <strong>QoS</strong> Model<br />

Catalyst 4500 —Conditionally-Trusted IP Phone + PC with Scavenger-Class <strong>QoS</strong> (Basic) Model<br />

Catalyst 4500—Conditionally-Trusted IP Phone + PC with Scavenger-Class <strong>QoS</strong> (Advanced)<br />

Model<br />

Catalyst 4500—Queuing<br />

The Catalyst 4500 with Supervisors II+, III, IV, and V can be found at either the access layer or the<br />

distribution layer of the campus. Furthermore, due to their high performance, they may also be found at<br />

the core layer of some campus networks.<br />

The <strong>QoS</strong> design options for access layer Catalyst 4500 design are shown in Figure 2-19; the distribution<br />

and/or core layer recommendations are shown in Figure 2-20.<br />
