3 VLAN

3.1 VLAN Basics

A Virtual LAN (VLAN) is a logical switched LAN formed by segmenting physical Local Area Networks (LANs).
Segmenting a switched LAN as one or more VLANs provides the following advantages:
⇒ Limits multicast and broadcast floods only to the required segments of the LAN to save LAN
bandwidth
⇒ Provides secured LAN access by limiting traffic to specific LAN segments
⇒ Eases management by logically grouping ports across multiple switches

VLANs work in same way as physical LANs. The packets from the end stations of a VLAN are switched only
to other end stations or network devices inside that VLAN. To reach devices in another VLAN, the packets
have to be routed from one VLAN to another. Supermicro L2/L3 switches support such Inter VLAN routing
to route packets across different VLANs. Inter VLAN routing is done by creating "Layer 3 Interface VLANs".

3.2 VLAN Support

Supermicro switches support the three types of VLANs: MAC based VLANs, protocol based VLANs and port
based VLANs.
