N3K-C3172TQ-XL Cisco Nexus 3172TQ-XL 48-port 10GBase-T Switch with 6x QSFP+ ports

The Cisco Nexus 3172PQ, 3172TQ, 3172TQ-32T, 3172PQ-XL, and 3172TQ-XL Switches are dense, high-performance, 10- and 40-Gbps Layer 2 and 3 switches that are members of the Cisco Nexus 3100 switch platform. All switches offer improved port density and scalability in compact one-rack-unit (1RU) form factors. The Cisco Nexus 3172 switches run the industry-leading Cisco® NX-OS Software operating system, which helps ensure continuous availability and sets the standard for mission-critical data center environments. They are well suited for data centers that require cost-effective, power-efficient line-rate Layer 2 and 3 top-of-rack (ToR) switches. These switches also support forward and reverse airflow (port-side exhaust and port-side intake) schemes with AC and DC power inputs.

The Cisco Nexus 3172PQ-XL and Cisco Nexus 3172TQ-XL are minor hardware revisions of the Cisco Nexus 3172PQ and 3172TQ, 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. The Cisco Nexus 3172PQ-XL and 3172TQ-XL also have 2.5-GHz CPUs

The Cisco Nexus 3172 switches provide the following main benefits:

• Wire-rate Layer 2 and 3 switching on all 72 10 Gigabit Ethernet ports
• The Cisco Nexus 3172 switches provide Layer 2 and 3 switching of up to 1.4 terabits per second (Tbps) and up to 1 billion packets per second (bpps) in a compact 1RU form factor.
• High availability
• Virtual port-channel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol. It also enables fully utilized bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models.
• The 64-way equal-cost multipath (ECMP) routing enables the use of Layer 3 fat-tree designs and allows organizations to prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
• Advanced reboot capabilities are included through In Service Software Upgrade (ISSU) and Fast Reboot capabilities.
• Power-supply units (PSUs) and fans are hot swappable.
• High performance
• The Cisco Nexus 3172 switches deliver ultra-low nominal latency, which allows customers to implement high‑performance infrastructure for high-frequency trading (HFT) workloads.
• Purpose-built on the NX-OS operating system with comprehensive, proven innovations
• Power-on auto provisioning (POAP) enables touchless bootup and configuration of the switch, drastically reducing provisioning time.
• Cisco Embedded Event Manager (EEM) and Python scripting enable automation and remote operations in the data center.
• Advanced buffer monitoring reports real-time buffer use per port and per queue, which allows organizations to monitor traffic bursts and application traffic patterns.
• Ethanalyzer is a built-in packet analyzer for monitoring and troubleshooting control-plane traffic and is based on the popular Wireshark open-source network protocol analyzer.
• Precision Time Protocol (PTP; IEEE 1588) provides accurate clock synchronization and improved data correlation with network captures and system events.
• Complete Layer 3 unicast and multicast routing protocol suites are supported, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol-Independent Multicast sparse mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).
• Network traffic monitoring with Cisco Nexus Data Broker
• Build simple, scalable and cost-effective network test access point (TAP) or Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.
