You have read a little about the advantages of VLANs and you want to become more knowledgeable in case one of your clients describes a need for which a VLAN would be a perfect solution.

What are some factors that would influence your decision to suggest a VLAN? What types of things would the client need to describe to you?

Virtual (or software-configured) local area networks can make network management simpler for you and improve the experience for your end users. If you’re new to setting up VLANs, you’ll want to start by getting an understanding of the different types you’ll need to create and also some of the benefits it can have to your business. This post describes five of the most common types of VLANs, as well as the top reasons to implement them.

VLAN Types

Most VLANs will be one of five main types, depending on their purpose:

Management VLAN:

A best practice is to set up a separate VLAN for management traffic like monitoring, system logging, SNMP, and other potentially sensitive management tasks. This ensures that bandwidth for management will be available even when user traffic is high.

Data VLAN:

Also known as a user VLAN, the data VLAN is designated only for user-generated data. How you group your data VLANs. (Such as by department or workgroup, for example) will depend on your organization’s structure and business processes. Look at your entire possible VLAN landscape and spend some time assessing the logic for how to best group your users.
