Categories: ,


The Cisco Nexus 9300 platform consists of fixed-port switches designed for top-of-rack (ToR) and middle-of-row (MoR) deployment in data centers that support enterprise applications, service provider hosting, and cloud computing environments. They are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet switches with up to 2.56 terabits per second (Tbps) of internal bandwidth. Cisco Nexus 9372PX-E Switch (N9K-C9372PX-E) is a minor hardware revision of the Cisco Nexus 9372PX. Enhancements include hardware capability for IP-based endpoint group (EPG) classification in Cisco ACI mode.
