What is the Cisco Nexus 3000 Series Switches?

The Cisco Nexus®3000 Series Switches are a comprehensive portfolio of 1, 10, and 40 Gigabit Ethernet switches built from a switch-on-a-chip (SoC) architecture. Introduced in April 2011, this series of switches provides line-rate Layer 2 and 3 performance and is suitable for top-of-the-rack (ToR) architecture. This series of switches has established itself as a leader in high-frequency trading (HFT), high-performance computing (HPC), and big data environments by pairing high performance and low latency with innovations in performance visibility, automation, and time synchronization.

What's the difference between the Cisco Nexus 3548 and 3524 Switches?

The Cisco Nexus 3548 and 3524 Switches are based on identical hardware, differentiated only by their software licenses, which allow the Cisco Nexus 3524 to operate 24 ports, and enable the use of all 48 ports on the Cisco Nexus 3548.

How many ports does N3K-C3548P-10GX have?

It have 48 fixed SFP+ ports (1 or 10 Gbps)
