Sample Configurations
The following configurations illustrate how to configure the Cisco Nexus 5000 Series for vPC with a fabric extender
straight-through topology, with MST as the Spanning Tree Protocol, with the multicast optimize feature, and with a
generic QoS policy based on four traffic classes (CriticalData, Scavenger, Voice, and class-default) that needs
to be customized.
