Cisco Public Chapter 2 Objectives Design and plan VLANs, trunks, and addressing to meet business requirements, technical requirements, and constraints. Configure VLANs and VLAN trunks in the campus network to support business and technical requirements. Configure VTP in the campus network to support business and technical requirements. Describe private VLANs and configure private VLANs in the campus network to support business and technical requirements. Configure and verify an EtherChannel in a Layer 2 topology that contains bridging loops.

Chapter 2 4 © 2007 – 2010, Cisco Systems, Inc. All rights reserved. Cisco Public Virtual Local Area Network (VLAN) A VLAN is a logical group of end devices. Broadcasts are contained within VLANs. Modern design: 1 VLAN = 1 IP subnet=1 broadcast domain. Trunks connect switches so as to transport multiple VLANs. Layer 3 devices interconnect VLANs.

Chapter 2 5 © 2007 – 2010, Cisco Systems, Inc. All rights reserved. Cisco Public End-to-End VLANs Each VLAN is distributed geographically throughout the network. Users are grouped into each VLAN regardless of the physical location, theoretically easing network management. As a user moves throughout a campus, the VLAN membership for that user remains the same. Switches are configured for VTP server or client mode.

Chapter 2 6 © 2007 – 2010, Cisco Systems, Inc. All rights reserved. Cisco Public Local VLANs Create local VLANs with physical boundaries in mind rather than job functions of the users. Local VLANs exist between the access and distribution layers. Traffic from a local VLAN is routed at the distribution and core levels. Switches are configured in VTP transparent mode. Spanning tree is used only to prevent inadvertent loops in the wiring closet. One to three VLANs per access layer switch recommended.
