auto: Specifies to determine the interface rate through auto-negotiation. 

Use the speed command to configure Ethernet interface data rate. 

Use the undo speed command to restore Ethernet interface data rate. 

By default, the port speed is in the auto-negotiation mode. 

Related commands: duplex, speed auto. 

 

You are recommended to configure the same port rate and duplex mode on two ports connected to 

each other, for example, set the duplex mode of both ports to auto negotiation or full/half duplex, so as 

to avoid packet loss.  

 

# Configure the interface rate as 100 Mbps for interface Ethernet 2/0/1.

10: Specifies the interface auto-negotiation rate as 10 Mbps. 

100: Specifies the interface auto-negotiation rate as 100 Mbps. 

1000: Specifies the interface auto-negotiation rate as 1000 Mbps. 

Use the speed auto command to configure the auto-negotiation rate of the current interface. 

Use the undo speed command to restore the default. 

If you repeatedly use the speed command and the speed auto command to configure the rate of an 

interface, only the latest configuration takes effect. For example, if you configure speed 100 after
