Catalyst 6500 PFC2/PFC3—QoS Considerations and Design Configuration 2-94 Enterprise QoS Solution Reference Network Design Guide Chapter 2 Campus QoS Design In the Conditionally-Trusted IP Phone + PC + Scavenger (Basic) Model for the Catalyst 6500 (CatOS), four aggregate policers are defined, one each for Voice from the VVLAN, call signaling from the VVLAN, all other traffic from the VVLAN, and for all PC Data traffic. Conditional trust is extended to the IP Phones via the trust-device command, as shown below.

Chapter 2 Campus QoS Design Catalyst 6500 CatOS QoS Verification Commands Version 3.3 Catalyst 6500 PFC2/PFC3—QoS Considerations and Design Catalyst 6500 CatOS QoS verification commands for the Conditionally-Trusted IP Phone + PC + Scavenger (Basic) Model include the following: show qos status show qos maps show port qos show qos acl show qos policer show qos statistics Note As previously mentioned, on non-GigabitEthernet linecards that use 2Q2T Transmit Queuing and 1Q4T Receive queuing (such as the WS-X6248-RJ-xx and the WS-X6348-RJ-xx), a hardware limitation prevents the proper functioning of port-based trust (which affects trust-cos, trust-ipprec, and trust-dscp). On such linecards, a workaround ACL can be used to achieve trust functionality. For such an example, see the Catalyst 6500 Trusted Endpoint Model section (Example 2-50) of this chapter. Catalyst 6500—Conditionally-Trusted IP Phone + PC with Scavenger-Class QoS (Advanced) Model This section includes the following topics: Configuration Catalyst 6500 CatOS QoS Verification Commands The Catalyst 6500 Conditionally-Trusted IP Phone + PC + Scavenger (Advanced) Model leverages the Dual-Rate Policing capabilities of the PFC2/PFC3. This feature is described in the Catalyst 6500 Untrusted Server + Scavenger section of this chapter (which applies the feature to Server-to-Client flows). In this example, the Dual-Rate Policing feature is applied to Client-to-Server flows to complement the Untrusted Server + Scavenger Model. Dual-Rate Policing, in this context, allows for graduated markdown of Interactive-Video (from PCs), Transactional Data, and Bulk Data. Specifically, in this example Interactive-Video is marked down to AF42 if it is in excess of 300 kbps but less than 500 kbps; if it is greater than 500 kbps, it is marked down to Scavenger (CS1). Similarly, Transactional Data and Bulk Data are marked down to AF22 and AF12 (respectively) if they are in excess of 3 Mbps but less than 5 Mbps; if they are in excess of 5 Mbps, then they are both marked down to Scavenger (CS1). All other policers are consistent with the single-rate policer model. The Catalyst 6500 PFC2/PFC3 Conditionally-Trusted Endpoint Dual-Rate Policing—IP Phone + PC + Scavenger (Advanced) Model is illustrated in Figure 2-25.
