Description
Cisco Nexus31128PQ Network Switch Kenya
The Cisco Nexus31128PQ Kenya comes in a compact two-rack-unit (2RU) form factor and runs the industry-leading Cisco® NX-OS Software operating system, providing customers comprehensive features and functions that are widely deployed. The Cisco Nexus31128PQ Kenya Switch is a dense, high-performance Layer 2 and 3, 10- and 40-Gbps switch that is a member of the Cisco Nexus 3100 switches. The Cisco Nexus31128PQ Kenya features the second-generation Cisco Nexus 3000 series and offers improved port density, scalability, and features compared to the first-generation switches. It supports both forward and reverse (port side exhaust and port side intake) airflow schemes with AC and DC power inputs. The Cisco Nexus31128PQ Kenya is well suited for data centers that require a cost-effective, power-efficient line-rate Layer 2 and 3 access or leaf switch.
Features
Wire-rate Layer 2 and 3 switching on all ports
 The Cisco Nexus31128PQ Kenya features Layer 2 and 3 switching of up to 2.5 Terabits per second (Tbps) and up to 1.4 Billion packets per second (bpps) is provided in a compact 2RU form-factor switch.
High availability
- Cisco Nexus31128PQ Kenya has Virtual PortChannel (vPC) technology providing Layer 2 multipathing through the elimination of Spanning Tree Protocol and 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.
- Hot swappable Power-Supply Units (PSUs) and fans.
High Performance
The Cisco Nexus31128PQ Kenya delivers low nominal latency, which enables customers to implement high-performance infrastructure for High-Frequency Trading (HFT) and High-Performance Computing (HPC) workloads.
Purpose-built Cisco NX-OS operating system with comprehensive, proven innovations
- PowerOn 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 utilization 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).
