Platform: Cisco Nexus 3000 Series Target Audience: Network Engineers, Data Center Architects, IT Procurement Introduction The Cisco Nexus 9372PX-E remains a workhorse in many top-of-rack (ToR) data center deployments. Built on the NX-OS operating system, this 1RU switch delivers line-rate Layer 2/3 switching with dense 10G SFP+ and 40G QSFP+ ports.
