Interface capability
The interface capability attribute displays the number of interface capabilities. The attribute is
a structure with two main elements: Function bits and speed/duplex options
Bit(s)

Definition
trol attribute (#6).
0 = Indicates that changes made to the interface control attribute (#6) will be-
come effective without resetting the device. The bit takes on this value when the
interface control attribute (#6) is not implemented.
1 = Indicates that changes made to the interface control attribute (#6) are not
applied automatically but will only become effective by resetting the device.
Note: This bit is repeated in the interface bit memory attribute (#2) to ensure
backward compatibility with earlier object revisions.
0 = Indicates that the interface does not support link autonegotiation.
1 = Indicates that the interface supports link autonegotiation.
0 = Indicates that the interface does not support automatic MDIX mode.
1 = Indicates that the interface supports MDIX mode.
0 = Indicates that the interface does not support manual setting of speed/duplex.
The interface control attribute (#6) is not supported.
1 = Indicates that the interface supports manual setting of speed/duplex via the
interface control attribute (#6).
