Speed of DataType UInt64 specifies the configured, negotiated, or actual speed of an Ethernet port in entities of 1 Mb/s (data rate). The default value is implementation-dependent (see IEEE Std 802.3).

Duplex of DataType Duplex represents the configured, negotiated, or actual duplex mode of an Ethernet port (see IEEE Std 802.3, clause 30.3.1.1.32, “aDuplexStatus”). The Duplex DataType is defined in 5.3.1.1.

MaxFrameLength of DataType UInt16 indicates the MAC frame length (including FCS bytes) at which frames are dropped for being too long (see IEEE Std 802.3, clause 30.3.1.1.37, “aMaxFrameLength”).

The component Variables of the IIeeeBaseEthernetPortType have the Attribute values defined in Table 4.
