One of the design requirements is to isolate other network traffic and broadcast from finance department to improve security. In order for this to possible we will implement VLAN on the network. This implementation will meet ECCMC business goals requirement, although VLAN implementation allow us to meet the requirement, it also allow the company network to be divided into logical group in order to achieve scalability requirement.
Implementing VLANs on the ECCMC network will allow the IT support to be able to manage users and their workstation by grouping them according to their functions. For instance new user's workstation from personnel department can be added to the oxford branch verse versa without much configuration.
Another reason why we are implementing VLANs, is because future growth of 5% yearly is expected, with this in place the technical goal in area of scalability will be achieved as new employee can place anywhere in the network without affecting the physical and logical design of the network.
