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.
