Catalyst 6500—Untrusted PC + SoftPhone with Scavenger-Class <strong>QoS</strong> Model<br />

This section includes the following topics:<br />

Catalyst 6500 CatOS <strong>QoS</strong> Verification Commands<br />
The radical difference in syntax between CatOS and IOS becomes increasingly apparent as more<br />
complex access edge models are presented.<br />
In the Untrusted PC + SoftPhone + Scavenger Model, shown below, per-application aggregate policers<br />
are defined—one each for SoftPhone VoIP traffic, SoftPhone call signaling traffic, and PC Data traffic.<br />
Then an ACL (titled “SOFTPHONE-PC-mod-port”) with multiple ACEs is defined, with each ACE<br />
referencing its associated aggregate policer. Once complete, the ACL is committed to PFC memory and<br />
then mapped to the desired switch port(s). Switch responses to the commands have been omitted to<br />
simplify the example.<br />
