speed Command
The speed command is used to set the communication speed of the interface. The speed
setting is only used on copper Ethernet interfaces (RJ-45), with the fiber Gigabit Ethernet
interfaces set to a speed of 1000 Mbps by default using the nonegotiate syntax. You can use
the speed command to set the speed on the interface to 10 Mbps or 100 Mbps. Additionally,
you can set the speed command to autodetect the speed of the interface from the line
connected to the interface using the auto syntax. Table 6-6 describes the command
parameters for the speed command, which must be used in the interface configuration mode.
The syntax for the speed command is as follows:
speed {auto | 10 | 100 | nonegotiate}
