Virtual Local Area Networks (VLANs) are extensively used in enterprise networks. However, their configuration remains an ad-hoc, complex and error-prone process today. The authors believe that to eliminate these difficulties, there is need for automation tools, and also need for visualization tools. In this paper, they report on their experience building a VLAN management toolkit, which automates and visualizes common VLAN configuration tasks. They begin by describing common mis-configurations, and their impact on network performance and security. They next present a set of algorithms that automate the VLAN configuration tasks. These algorithms form the back end of the toolkit.
