Except for the 1000BASE-T SFP modules, if an SFP module port is connected to a device that does not

support autonegotiation, you can configure the speed to not negotiate (nonegotiate).

If the speed is set to auto, the switch negotiates with the device at the other end of the link for the speed

setting and then forces the speed setting to the negotiated value. The duplex setting remains as

configured on each end of the link, which could result in a duplex setting mismatch.

If both ends of the line support autonegotiation, we highly recommend the default autonegotiation

settings. If one interface supports autonegotiation and the other end does not, do use the auto setting on

the supported side, but set the duplex and speed on the other side.

Changing the interface speed and duplex mode configuration might shut down and re-enable the

interface during the reconfiguration.

For guidelines on setting the switch speed and duplex parameters, see the software configuration guide

for this release.

This example shows how to set speed on a port to 100 Mbps:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# speed 100

This example shows how to set a port to autonegotiate at only 10 Mbps:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# speed auto 10

This example shows how to set a port to autonegotiate at only 10 or 100 Mbps:

Switch(config)# interface gigabitethernet0/1

Switch(config-if)# speed auto 10 100

You can verify your settings by entering the show interfaces privileged EXEC command.
