Cisco no longer has one “premium” data center switch. Instead, the Nexus line is a swarm of specialized hardware, each running a tailored version of NX-OS.
You must explicitly enable features (e.g., feature vpc , feature ospf ) before configuring them, which helps save system resources. Cisco no longer has one “premium” data center switch
To support the massive "east-west" traffic (server-to-server) found in modern clouds, NX-OS implemented FabricPath (based on TRILL) and later VXLAN (Virtual Extensible LAN) known for high-performance VDC support.
In the rapidly evolving landscape of enterprise networking, the transition to architectures has become a strategic imperative. At the heart of this transformation is the Cisco Nexus switching portfolio , powered by the NX-OS operating system . Originally built on a modular, Linux-based foundation, NX-OS has evolved from a robust storage-networking derivative into the industry’s most deployed data center OS. The Foundation: NX-OS Architecture and Modularity feature ospf ) before configuring them
