VLAN tagging
A local network can be divided into logical subnetworks known as VLANs (VLAN = Virtual
Local Area Network, Standard IEEE 802.1Q). 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 of different services (Internet telephony,
Internet TV etc.) 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 differ-
ent VLANs. In this case, you enter the VLAN identifiers (VLAN tags) for your VLAN. Your net-
work operator will supply you with this data.
Warning
If you operate the PC in a different VLAN from the phone, you will no longer have direct
access to the Web configurator of the phone from the PC.
