The data rate of this port in bits per second. For example, a standard Ethernet port (e.g. 10BASE-T) would indicate a value of ten-megabits-per-second((1) indicating that the port supports a data rate of 10Mb/s. For ports that can change their data rate (e.g. 10/100 ports), the value of this object indicates the current state of the port's speed capability.
