Performance Benchmarks and Testing Results
The Cisco Nexus 9348GC-FXP (N9K-C9348GC-FXP) is a high-performance, 1-rack-unit (1RU) top-of-rack (ToR) switch designed for use in data center networks. It features 48 fixed ports, supporting speeds of up to 100 Gbps, and is powered by the Cisco Cloud Scale ASIC.
To measure the performance of the Cisco Nexus 9348GC-FXP switch, various benchmarks and tests can be conducted. These tests can evaluate the switch's throughput, latency, and other key performance metrics.
One common benchmark used to evaluate switch performance is the RFC 2544 test. This test involves measuring the maximum throughput of the switch while simultaneously introducing latency and packet loss. The results of this test can help network administrators determine the maximum traffic that the switch can handle without introducing significant latency or packet loss.
Another commonly used test for switch performance is the Y.1564 test. This test is used to measure the maximum throughput of the switch while simultaneously evaluating latency and jitter. This test can help network administrators determine the quality of service (QoS) that can be achieved with the switch.
In addition to these standardized tests, network administrators can also conduct their own tests to evaluate the performance of the Cisco Nexus 9348GC-FXP switch in their specific network environment. These tests can be used to measure traffic patterns, latency, and other key metrics in real-world scenarios.
Configuration and Management Options
The Cisco Nexus 9348GC-FXP (N9K-C9348GC-FXP) is a rack-mountable switch that provides high-density, low-latency connectivity for data center and campus networks. It has 48 ports, including 40 Gigabit Ethernet (GbE) and 8 Quad Small Form-Factor Pluggable Plus (QSFP+) ports, and supports a variety of network protocols and technologies.
To configure and manage the Cisco Nexus 9348GC-FXP switch, there are several options available:
- Command Line Interface (CLI): The CLI is a text-based interface that allows you to configure and manage the switch using commands. It provides a wide range of options for configuring the switch, including VLANs, Layer 2 and 3 protocols, security features, and more.
- Web-based GUI: The switch also has a web-based GUI that provides a graphical interface for managing and configuring the switch. It is a user-friendly option for those who prefer a point-and-click interface.
- Simple Network Management Protocol (SNMP): SNMP is a network protocol that allows you to monitor and manage network devices, including the Cisco Nexus 9348GC-FXP switch. It provides a standardized way to manage and configure the switch from a central location.
- Cisco Network Assistant: Cisco Network Assistant is a free software tool that provides a centralized management interface for Cisco switches. It can be used to configure and manage the Cisco Nexus 9348GC-FXP switch, as well as other Cisco devices on the network.
- Application Programming Interface (API): The switch also provides an API that allows developers to write scripts or applications to manage and configure the switch. This can be a useful option for automating repetitive tasks or integrating the switch with other network management tools.
Maintenance and Troubleshooting Tips
The N9K-C9348GC-FXP Cisco Nexus 9348GC-FXP switch is a high-performance, 48-port switch designed for use in data center environments. It offers advanced features such as virtual PortChannel (vPC), FabricPath, and support for Fibre Channel over Ethernet (FCoE).
To keep the switch running smoothly and avoid downtime, it's important to perform regular maintenance and troubleshooting. Here are some tips to help you do that:
- Regularly check the firmware and software versions of the switch, and upgrade them if needed. This can help improve performance and fix known bugs and vulnerabilities.
- Monitor the temperature and airflow of the switch, and ensure that it stays within safe operating ranges. Overheating can cause performance issues and hardware damage.
- Keep the switch clean and free of dust and debris. Use compressed air or a vacuum cleaner to remove dust from the switch vents and fans.
- Check the power supply and cables regularly to ensure that they are functioning properly. Make sure that the power supply is compatible with the switch and provides sufficient power.
- Use the management and monitoring tools provided by Cisco to monitor the switch performance, logs, and traffic. This can help you identify issues and troubleshoot problems.
- Test the switch regularly to ensure that it is performing as expected. You can use tools such as Iperf or Jperf to test network throughput and latency.
- Configure the switch to meet the requirements of your network, such as VLANs, QoS, and routing protocols. Make sure that the configuration is backed up regularly and can be restored in case of a failure.
- If you encounter issues with the switch, check the Cisco support website for troubleshooting guides and resources. You can also contact Cisco support for assistance.
- Ensure that the switch is connected to a backup power supply or UPS to prevent power outages and protect the switch from electrical surges.
- Keep track of the switch's capacity and plan for expansion if needed. The 9348GC-FXP supports expansion modules for additional ports and features.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
