The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS commands that begin with N that are used to manage a Cisco Nexus 2000 Series Fabric Extender from a Cisco Nexus 6000 series switch.
To enable the autonegotiation protocol to configure the speed, duplex, and automatic flow-control of the Gigabit Ethernet interface, use the negotiate command in interface configuration mode. To disable automatic negotiation, use the no negotiate auto command.

The no negotiate auto command is supported only in Cisco Nexus 2248PQ 10GE Fabric Extender, Cisco Nexus 2232PP 10GE Fabric Extender, and Cisco Nexus 2348UPQ 10GE Fabric Extender with 1G-based SFP.
