Configuring Link Dependencies
Beginning in Privileged EXEC mode, use the following commands to 
configure ports that are dependent on the state of other ports.
speed {10 
|100|1000|10000 | auto 
[100|1000|10000]}
Configure the speed of a given Ethernet interface or allow 
the interface to automatically detect the speed.
If you use the 1001000, or 10000 keywords with the auto 
keyword, the port auto-negotiates only at the specified 
speeds. Setting the speed without the auto keyword forces 
the speed to the selected value and disables auto-
negotiation. It is possible to configure a fiber port for a 
speed not supported by the transceiver. In this case, the 
port will not link up.
On combo ports, it is possible to configure auto 
negotiation even if only the fiber interface is active. The 
auto negotiation settings will be utilized when the copper 
port is active. Auto negotiation settings are ignored for the 
fiber ports, as fiber ports alway operate in full-duplex  
fixed-speed mode.
