When transmitting VLAN tagged networks via provider networks that use VLAN themselves, providers sometimes use special VLAN tagging IDs. In order to set VLAN transmission on the LANCOM to accommodate this, the Ethernet2 type of the VLAN tag can be set as a 16-bit hexadecimal value as 'tag value' under Setup/LAN Bridge/VLAN or in LANconfig in the configuration area under 'Interfaces' using the 'VLAN' tab in the field 'VLAN tag'. The default is '8100' (802.1p/q VLAN tagging) other typical values for VLAN tagging could be '9100' or '9901'
