Cisco NX-OS: Paving the Way for the Future
With those new to NX-OS, a natural and legitimate question centers around the similarities and differences between the more familiar IOS and the newer NX-OS; this paper serves to answer that very inquiry.
With the introduction of the Nexus Series of Data Center switches, Cisco created the Nexus Operating System, commonly abbreviated NX-OS. While certainly not exhaustive, the Nexus switch line includes the 7000, 5000, 2000 (fabric extenders), and the 1000V Virtual Switch. While these devices were intended for use in the Data Center, models such as the venerable Catalyst 6500 series have been increasingly displaced by corresponding Nexus models in the core.
