VLAN
VLAN (Virtual Local Area Network) is used to divide a physical network logically into several
broadcast domains. VLAN membership can be configured through software instead of
physically relocating devices or connections. Grouping devices with a common set of
requirements regardless of their physical location can greatly simplify network design. VLANs
can address issues such as scalability, security, and network management.
The purpose of VLAN configurations on the endpoint is to insert a tag with VLAN information to
the packets generated by the endpoint. When VLAN is configured on the endpoint properly, the
endpoint will tag all packets with the VLAN ID. The switch receives and forwards the tagged
packets to the corresponding VLAN according to the tag’s VLAN ID, as described in IEEE Std
802.3.
In addition to manual configuration, the endpoint also supports automatic VLAN discovery via
LLDP or DHCP. The assignment takes effect in the following order: assignment via LLDP, manual
configuration, then assignment via DHCP.
