Vlan - Matrix Sparsh VP110 User Manual

VLAN

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.
In addition to manual configuration, the IP phone also supports automatic discovery of VLAN via LLDP or DHCP.
The assignment takes effect in this order: assignment via LLDP, manual configuration, then assignment via DHCP.
VLAN Discovery via DHCP
IP phones support VLAN discovery via DHCP. When the VLAN Discovery method is set to DHCP, the IP phone will
examine DHCP option for a valid VLAN ID. The predefined option 132 is used to supply the VLAN ID by default.
You can customize the DHCP option used to request the VLAN ID.
Procedure
VLAN can be configured using the configuration files or locally.
