The 1000BASE-SX SFP module ports support the nonegotiate keyword in the speed interface configuration command. Duplex options are not supported.


If you are connected to a device that does not support autonegotiation, you can configure speed on copper SFP module ports; however, you can only configure fiber SFP module ports to not negotiate (nonegotiate).


When configuring an interface speed and duplex mode, note these guidelines.
