This table should contain a single entry for each available LAN and WAN interface. For a WAN interface, this parameter is the full hierarchical parameter name of a particular WANConnectionDevice. A WANConnectionDevice is considered available (included in this table) only if it supports layer-2 bridged traffic. That is, this table MUST include only WANConnectionDevices that contain either a WANEthernetLinkConfig object, or that contain a WANDSLLinkConfig object for which the LinkType is EoA (Ethernet over ATM). For example: InternetGatewayDevice.WANDevice.1.WANConnectionDevice.2 For a LAN interface, this parameter is the full hierarchical parameter name of a particular LAN InterfaceConfig object, or a WLANConfiguration object. This table SHOULD include one entry for each such object. For example: InternetGatewayDevice.LANDevice.1.LANEthernetInterfaceConfig.2 For a WAN-side connection to the Gateway's IP router, this parameter is the full hierarchical parameter name of a particular WANConnection service. This table SHOULD include an entry for each layer-3 WAN connection. For example: InternetGatewayDevice.WANDevice.1.WANConnectionDevice.2.WANPPPConnection.1 For a LAN-side connection to the Gateway's IP router, this parameter is the full hierarchical parameter name of a particular LANDevice. This table SHOULD include an entry for each LANDevice, each of which is associated with a LAN-side layer-3 connection to the Gateway's IP router. For example: InternetGatewayDevice.LANDevice.2
