Cisco Catalyst QoS: Quality of Service in Campus Networks

Core Layer 397

Catalyst 6500 Hybrid MSFC

Example 10-6 illustrates the Catalyst 6500 Hybrid Multilayer Switch Feature Card (MSFC)

sample configuration applied to Figure 10-1.

The campus network design uses redundant Internet connections. A FlexWAN module in

the Catalyst 6500s connects the Internet directly to T3s. To drop excess traffic transmitted

on the interface, the FlexWAN uses a shaper. The policy map uses a class map that matches

all traffic to shape the egress traffic out the serial interface to 45 Mbps. In this example, the

shaper uses a committed burst rate of 180 kbps and an excess burst rate of 180 kpbs.
