IT/242 February 24, 2013 VLAN Virtual Local Area Networks (VLAN) is a logical subgroup within a Local Area Network that is created with software on a networking switch (PC Magazine Encyclopedia). Some networking switches have capabilities of utilizing VLAN configurations, but not all. VLANs function at Layer 2 of the OSI model, the main purpose is to isolate network traffic within the VLAN. This will improve performance be dividing a LAN into several smaller VLANs. Setting up the network switch for users to continue to use applications without network lagging will be achieved by creating floor-by-floor VLAN interfaces. Marketing can use VLAN 1, VLAN 2 will be configured for Engineering, VLAN 3 configured for Operations and VLAN 4 for the Call Center staff. Having the network set up into sections will make for a more secure network and will limit traffic on the network. Having control of the network traffic with these segments will also help with access to needed resources. Limiting access to specific ports for each devise will allow for future reorganization. If a user moves to a new location, the unique MAC address and the assigned static IP address can be reserved. This will also increase security by limiting access by MAC address. This will keep other devises from accessing resources. These solutions will also be achieved by using a Layer 3 switch. Using this will provide greater control on the LAN. The type of trunking protocol that will be used for this scenario is IEEE 802.1Q. Using this protocol is not proprietary and will allow for using more than one type of network switch manufacture. This route will allow for the organization to purchase networking devises that are suitable for the company and allow for future expansions. Administering will be automated by using VLAN Trucking Protocol. VTP will reduce overhead and allow for scalability of the network. The backup plan would include of having physical map of the network in case of a power outage or reconfiguring of the network. My organization has CAD drawings of all our devices. These drawings are also locked up and stored so that only authorized personnel to view.
