Why Create a VLAN
Due to the changes happening within the company, expansion of the call center, employees moving around within the building, and employees moving off site there is a need for change to the network. Virtual Local Area Network (VLAN) is the most obvious choice because “the VLAN solution can help reduce costs by allowing us to purchase fewer router ports. It also gives us the flexibility of physically placing and moving our clients anywhere in the organization, while still including them virtually within their own subnet. We can also contain broadcasts within the network, thereby freeing up network resources. From a security perspective, it allows us very granular control of the network.” (McIntire, 2001) The Plan
In order to accommodate the changes the network needs due to expansion and relocation the Local Area Network (LAN) must be segmented into different broadcast domains through the use of the VLAN. Incorporating the VLAN will reduce the number of router hops and increase the apparent bandwidth for the user. Security
To improve security, separating systems that have sensitive data from the rest of the network decreases the chances that people will gain access to information they are not authorized to see. VLAN Memberships
VLAN membership will be of the Dynamic type. The Dynamic VLANs switch automatically assigns the port to a VLAN. Because there are changes happening quickly and employees being added and moved to new locations this membership type would work best. It can be assumed that with the growth of the company that there will be more employees being moved and location changes continuing.
A layer 2 switch will be used on the VLAN. With a layer 2 switch multiple layer 3 networks can be created from the same layer 2 switch. This layer 3 is the same layer that IP subnets are created on. Trunking
Trunking will be used to allow for multiple VLANs and multiple...
