Medianet Campus Cisco Catalyst 6500 Supervisor 2T
Role in Medianet Campus Network
The Cisco Catalyst 6500 series switches with Supervisor 2Ts are well-suited to the role of distribution- or core-layer switches in medianet campus networks. As such, these switches typically connect directly to other switches or routers, as shown in Figure 1.

QoS Design Steps
There are two main steps to configure QoS on Cisco Catalyst 6500 series switches with Supervisor 2T:
1. Configure Ingress Queuing
2. Configure Egress Queuing
Step 1: Configure Ingress Queuing
The medianet 8Q4T ingress queuing model for the Cisco Catalyst 6500 with Supervisor 2T is shown in Figure 2.

Step 2: Configure Egress Queuing
The medianet 1P7Q4T egress queuing model for the Cisco Catalyst 6500 with Supervisor 2T is shown in Figure 3.
Figure 3 Catalyst 6500 Sup2T (1P7Q4T) Egress Queuing Model
Ingress QoS policies on the Cisco Catalyst 6500 are configured on the logical Port-Channel interface (typically these are simply to enable DSCP trust, which is enabled by default on the Sup2T) , while egress QoS policies are configured on the physical port-member interfaces.
Cisco Validated Design (CVD)
The Cisco Validated Design for Cisco Catalyst 6500 series switches with Supervisor 2T in the role of a distribution- or core-layer switch in a medianet campus network is presented on the reverse.
