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.

Cisco Public Virtual Local Area Network (VLAN) A VLAN is a logical group of end devices with a common set of requirements interdependent of their physical location Ex. One VLAN covers different floors Broadcasts are contained within VLANs. One for each Modern design has 1 VLAN = 1 IP subnet. Trunks connect switches so as to transport multiple VLANs. Layer 3 devices interconnect VLANs.

Cisco Public Characteristics of End-to-End VLANs End-to-end VLAN refers to a single VLAN that is associated with switch ports dispersed through an enterprise network on multiple switches 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. Same IP subnet for all users Trunks are used to connect switches

Cisco Public Characteristics of Local VLANs All geographical users are grouped in the same switch and VLAN 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. (Do not need to be advertised to other switches) Spanning tree is used only to prevent inadvertent(not intentioned) loops in the wiring closet.
