5.2.1 IIetfBaseNetworkInterfaceType Interface ToC Previous Next index

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 (see IETF RFC 2863: The Interfaces Group MIB - ifAdminStatus). 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 (see IETF RFC 2863: The Interfaces Group MIB - ifOperStatus). 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 (see IETF RFC 2863: The Interfaces Group MIB - ifPhysAddress).

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 (see IETF RFC 2863: ifSpeed, ifHighSpeed).

The component Variables of the IIetfBaseNetworkInterfaceType have the Attribute values defined in Table 2.
