VLANs offer a method of dividing one physical network into multiple broadcast domains. In enterprise networks, these broadcast domains usually match with IP subnet boundaries, so that each subnet has its own VLAN. The advantages of VLANs include:
- Performance.
- Ease of management.
- Security.
- Trunks.
- You do not have to configure any hardware device, when physically moving your server to another location.
To set up VLANs, consult the following documentation:
- For Red Hat Enterprise Linux, go to https://docs.redhat.com and search for "configure tagged vlan traffic".
- For Ubuntu, go to https://help.ubuntu.com/ and search for "configure tagged vlan traffic".
