This article will provide a detailed explanation of the N3K-C3548P-10GX Nexus 3548X Managed Switch. We will explore its features, benefits, applications, and how it works, all in simple English.

To get a deeper understanding of the Cisco N3K-C3548P-10GX Nexus 3548X, let's dive into its key features and specifications. These details will shed light on the capabilities and how it can enhance your network infrastructure.

The Cisco Nexus 3548X is built on a high-performance architecture that can handle the demands of modern networks. It boasts a switching capacity of up to 960 Gbps, ensuring that your network can efficiently handle heavy workloads and traffic spikes. This high switching capacity is complemented by a forwarding rate of up to 720 Mpps making it suitable for data-intensive applications.

Low latency is critical in networking, especially for applications that require real-time data transfer and minimal delays. The Cisco N3K-C3548P-10GX Nexus 3548X excels in this aspect, offering ultra-low latency with a latency rate as low as 250 nanoseconds. This low latency is a game-changer for industries like finance, where split-second transactions can make a significant difference.

Energy efficiency is a growing concern in data centers and network infrastructure. The Cisco Nexus 3548X addresses this concern by featuring an efficient power supply and power management capabilities. It is designed to reduce power consumption while maintaining optimal performance. In addition, it supports the IEEE Data Center Bridging (DCB) standard, which helps in efficiently managing power usage.

The Cisco N3K-C3548P-10GX Nexus 3548X is highly scalable, allowing for the addition of more ports and features as your network requirements expand. This scalability ensures that your investment in this switch remains future-proof and adaptable to the changing needs of your organization.

Security is a top priority in networking, and this switch incorporates advanced security features to protect your data and network infrastructure. It supports features like Access Control Lists (ACLs), which enable administrators to control traffic flow and filter out unwanted data. Additionally, it offers features like DHCP Snooping and IP Source Guard to enhance security at the network layer.

For data centers, efficient and reliable operations are critical. The Cisco N3K-C3548P-10GX Nexus 3548X includes features like Virtual PortChannels (vPC) and FabricPath to simplify data center operations. vPC allows for the creation of redundancy and load-balancing configurations, ensuring high availability, while FabricPath simplifies Layer 2 network topology and improves network utilization.

The Cisco Nexus 3548X switch (N3K-C3548P-10GX model) supports several advanced features that are designed to enhance the performance and flexibility of data center networks. Some of these features include:

VXLAN is a network virtualization technology that enables the creation of virtual Layer 2 networks on top of existing Layer 3 infrastructure. This allows for the creation of thousands of virtual networks, which can be used to segment traffic and isolate different types of workloads.

OTV is a data center interconnect (DCI) solution that allows for the extension of Layer 2 networks across multiple data centers. This allows for the seamless movement of virtual machines (VMs) and other workloads between data centers, without the need for VLANs or other Layer 2 technologies.

FCoE is a technology that allows for the transport of Fibre Channel (FC) traffic over Ethernet networks. This allows for the consolidation of FC and Ethernet networks, reducing the need for multiple types of cables and switches in the data center.

This feature provides automated network verification and troubleshooting. It uses a combination of telemetry data, machine learning, and analytics to provide real-time visibility into network performance, identify potential issues, and recommend actions to resolve them.

RPVST+ is a Cisco-proprietary version of the Spanning Tree Protocol (STP) that allows for faster convergence and improved scalability in large Layer 2 networks. This helps to ensure that the network remains stable and resilient in the event of link failures or other disruptions.

The Cisco Nexus 3548X switch (N3K-C3548P-10GX model) offers several security features and capabilities to help ensure that the network is protected against unauthorized access, breaches, and other security threats. Some of these include:

Access control lists

The switch supports the use of ACLs, which are used to control access to the network and to specific resources. ACLs can be used to restrict access to certain IP addresses, ports, and protocols, and to apply different levels of access based on the user or device.

Cisco TrustSec

This is a security framework that provides identity-based security, allowing administrators to create policies that are based on the user or device, rather than on the IP address or port. This allows for more granular control over network access and can help to prevent unauthorized access or breaches.

Cisco NX-OS Software Security Features

The switch runs on Cisco NX-OS software, which includes a range of security features such as Role-Based Access Control (RBAC), Secure Shell (SSH), and Secure Copy (SCP) for secure remote management, and SSHv2 for secure access to the switch.

Compliance

The switch is compliant with various industry standards such as PCI-DSS, HIPAA, and SOX. This can help organizations to meet regulatory requirements and ensure that their network infrastructure is secure and compliant.

Cisco Software Checker

This is a feature that allows administrators to ensure that the switch is running the most recent, secure version of the software. It also alerts administrators of vulnerabilities and offers solutions to fix them.

These security features and capabilities can help to ensure that the Cisco Nexus 3548X switch and the network it is a part of are protected against unauthorized access, breaches, and other security threats, and also allow organizations to meet regulatory and compliance requirements.

Network Management and Security

The Cisco Nexus 3548X switch is a member of the Cisco Nexus 3500 platform, a series of data center switches designed for high-performance, high-density 10, 25, 40, 50, and 100 Gigabit Ethernet environments. The N3K-C3548P-10GX model has 48 ports with 10 Gigabit Ethernet connectivity and supports advanced features such as VXLAN, OTV, and FCoE.
