Catalyst 4500 Supervisor II+/III/IV/V—<strong>QoS</strong> Considerations and <strong>Design</strong><br />
Catalyst 4500—Untrusted Server with Scavenger-Class <strong>QoS</strong> Model<br />
Configuration<br />
This section includes the following topics:<br />
Configuration<br />
Catalyst 4500 <strong>QoS</strong> Verification Commands<br />
The Catalyst 4500 Untrusted Multi-Application Server with Scavenger-Class <strong>QoS</strong> model is show below.<br />
The main changes for the Catalyst 4500 for this model are the syntax defining the policed-DSCP map<br />
and the policer definitions (using the abbreviation mbps for megabits per second).<br />
