Appendix A, 

, introduces you to the IEEE 802.1D Spanning Tree 

Protocol. This protocol is used to resolve the problems of physical loops in a network by 
establishing one primary path between any two switches in a network.

Appendix B, 

, introduces you to IEEE 802.1Q-compliant virtual LANs 

(VLANs). This capability provides a highly efficient architecture for establishing VLANs within a 
network and for controlling broadcast/multicast traffic between workgroups.

Appendix C, 

, introduces you to the Class of Service capability, which is based on 

the IEEE 802.1p standard specification. This capability allows you to assign mission-critical data 
to a higher priority through the switch by delaying less critical traffic during periods of congestion. 
Higher priority traffic through the switch is serviced first before lower priority traffic.

Appendix D, 

, introduces you to the Internet Group Management Protocol 

(IGMP). This protocol runs between hosts and their nearest neighboring multicast switch. The 
protocol’s mechanisms allow a host to inform its local router that it wants to receive transmissions 
addressed to a specific multicast group.
