Summary

This chapter focused on VLAN fundamentals including the roles of VLANs, trunking, and VTP. The two most popular trunking implementations are ISL and IEEE 802.1Q. The preferred trunking configuration is Desirable-Desirable with IEEE 802.1Q implementation. VTP transparent mode is preferred over client/server mode because it is less likely to cause unexpected problems on the network. The discussion moved forward to address the significance behind pruning, Etherchannel, and VLAN 1. Management VLAN needs to have its own separate VLAN with non-redundant links as discussed. The chapter concluded with a discussion of private VLANs and their increased role in today's networks.
