BNM Ethernet Base Info

Speedof DataType UInt64specifies 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).

Duplexof DataType Duplexrepresents 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 DataTypeis defined in 5.3.1.1.

MaxFrameLength of DataType UInt16indicates 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 Variablesof the IIeeeBaseEthernetPortType have the Attributevalues defined in Table 4.
