VLAN (Virtual Local Area Network) is used to logically divide a physical network 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 IP phone is to insert tag with VLAN
information to the packets generated by the IP phone. When VLAN is properly
configured for the ports (Internet port and PC port) on the IP phone, the IP phone will tag
all packets from these ports with the VLAN ID. The switch receives and forwards the
tagged packets to the corresponding VLAN according to the VLAN ID in the tag as
described in IEEE Std 802.3.
VLAN on IP phones allows simultaneous access for a regular PC. This feature allows a PC
to be daisy chained to an IP phone and the connection for both PC and IP phone to be
trunked through the same physical Ethernet cable.
