Overview (N3K-C3172PQ-XL)

The Cisco Nexus 3172PQ-XL (N3K-C3172PQ-XL) is a 1 rack unit (RU) switch with 8GB of RAM and dual-core 2.5GHz x86 CPUs and 10-Gigabit enhanced small form-factor pluggable (SFP+) ports with 48 SFP+ ports and 6 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate in 100-Mbps, 1-Gbps, or 10-Gbps mode, and each QSFP+ port can operate in native 40-Gbps or 4 x 10-Gbps mode. The Cisco Nexus 3172PQ-XL is a minor hardware revision of the Cisco Nexus 3172PQ respectively. Enhancements include an additional 4 GB of memory (for a total of 8 GB). The additional memory allows users to perform object-model programming.

Faq (N3K-C3172PQ-XL)

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 configuration for the Cisco Nexus 3172PQ and 3172PQ-XL?

48 fixed 10 Gigabit Ethernet SFP+ ports (can operate at 100-Mbps, 1-Gbps, and 10-Gbps speeds) and 6 fixed QSFP+ ports (each QSFP+ port can support 4 x 10 Gigabit Ethernet or 40 Gigabit Ethernet)
