Nexus 3000 C3172PQ-10GE Switch Overview
The Cisco Nexus 3172PQ switch is a high-density, high-performance Layer 2 and Layer 3 switch, designed to support 10G and 40G connectivity. As a member of the Cisco Nexus 3000 series, the Nexus 3172PQ is well-suited for data centers requiring a cost-effective, power-efficient line-rate Layer 2 and Layer 3 top-of-rack (ToR) switch. This 1RU fixed form factor switch features 72 x 10 Gigabit Ethernet ports (with 48 SFP+ ports and 6 QSFP+ ports), where the 48 SFP+ ports support 1G and 10G Ethernet, and the 6 QSFP+ ports offer 4 x 10 Gigabit Ethernet or 40 Gigabit Ethernet each, providing flexible and high-bandwidth connectivity. Designed for scalability and reliability, the Nexus 3172PQ also includes redundant fans (3+1), 2 redundant power supplies, and management, console, and USB flash-memory ports. With a 1.4 Tbps switching capacity, a forwarding rate of up to 1 bpps, and the ability to handle line-rate traffic throughput across both Layer 2 and Layer 3 on all ports, this switch delivers outstanding performance for high-demand environments. It also supports configurable maximum transmission units (MTUs) of up to 9216 bytes (jumbo frames), ensuring efficient data handling. Shop Cisco Switch models like the N3K-3172PQ-10GE to take advantage of its up to 72x10G Ports, 48 SFP+ ports, 6 QSFP+ ports, and up to 40G Uplinks, making it an ideal choice for Cisco Data Center Switch needs.
