Configuring Port Characteristics 497
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 100, 1000, 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.
