This OPC UA Interface defines the basis of an IETF network interface. The IIetfBaseNetworkInterfaceTypeis formally defined in Table 1.

AdminStatusof DataType InterfaceAdminStatusspecifies the desired state of the network interface. This Variablehas the same read semantics as ifAdminStatus (see IETF RFC 2863: The Interfaces Group MIB - ifAdminStatus). The InterfaceAdminStatus Enumerationis defined in 5.3.1.2.
OperStatusof DataType InterfaceOperStatusspecifies the current operational state of the network interface. This Variablehas the same semantics as ifOperStatus (see IETF RFC 2863: The Interfaces Group MIB - ifOperStatus). The InterfaceOperStatus Enumerationis defined in 5.3.1.3.
PhysAddressof DataType Stringspecifies the network interface's address at its protocol sub-layer. For example, for an 802.x network interface, this parameter normally contains a Media Access Control (MAC) address. The network interface's media-specific modules must define the bit and byte ordering and the format of the value of this object. For network interfaces that do not have such an address (e.g., a serial line), this node is not present (see IETF RFC 2863: The Interfaces Group MIB - ifPhysAddress).
Speedof DataType UInt64specifies an estimate of the network interface's current bandwidth in bits per second. For network interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this Value should contain the nominal bandwidth (see IETF RFC 2863: ifSpeed, ifHighSpeed).
The component Variablesof the IIetfBaseNetworkInterfaceTypehave the Attributevalues defined in Table 2.
