A local network can be divided into logical subnetworks known as VLANs (VLAN = Virtual Local Area Network). Multiple VLANs share a physical network and its components, e.g., switches. Data packets from a VLAN are not forwarded to another VLAN. VLANs are often used to separate the data traffic or different services and to define different priorities for the data traffic.
You can operate your phone and a PC connected to the PC port on your phone in two different VLANs. In this case, you enter the VLAN identifiers for your VLAN.
VLAN is implemented from software version 1.2.4 or higher.
