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

AdminStatus of DataType InterfaceAdminStatus specifies the desired state of the network interface. This Variable has the same read semantics as ifAdminStatus (ifAdminStatus is defined in IETF RFC 2863). The InterfaceAdminStatus Enumeration is defined in 5.3.1.2.
OperStatus of DataType InterfaceOperStatus specifies the current operational state of the network interface. This Variable has the same semantics as ifOperStatus (ifOperStatus is defined in IETF RFC 2863). The InterfaceOperStatus Enumeration is defined in 5.3.1.3.
PhysAddress of DataType String specifies 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 (ifPhysAddress is defined in IETF RFC 2863).
Speed of DataType UInt64 specifies 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 (ifSpeed and ifHighSpeed are defined in IETF RFC 2863).
The component Variables of the IIetfBaseNetworkInterfaceType have the Attribute values defined in Table 2.
