Reference:Configuration/ETH/VLAN

If a network uses several VLANs (Virtual Local Area Network), a VLAN can be specified for every Ethernet interface . This ensures that the data packets are transmitted to the specified VLAN only.

• ID: The ID of the VLAN. The value 0 is applied if the ID entry field is empty. The VLAN ID with the value 0 switches the QoS (Quality of Service) off according to 802.1q.
• Priority: If the switch at the port to the innovaphone gateway happens to be configured to a different ID, the same value must be entered here to allow the Ethernet packets to be prioritised. A priority value between 0 and 7 is entered here (configuration on the Ethernet switch).
