Product Review

The Cisco N3K-C3048TP-1GE offers a solid foundation for small to medium-sized enterprise networks with its 48 fixed Gigabit Ethernet ports and 4 ten Gigabit Ethernet uplinks, facilitating efficient connectivity and high-speed data transfers. Its redundant power supplies and fans, along with a switching capacity of 176 Gbps and a forwarding rate of 132 Mpps, ensure reliable and continuous operation. However, the switch's limited layer 3 features and the modest size of its routing table may not meet the demands of complex networks requiring extensive routing capabilities and scalability.


The Cisco N3K-C3048TP-1GE switch is designed to meet the requirements of modern data centers and high-density networking environments. This device provides a comprehensive solution for scalable and efficient network infrastructure, incorporating a range of features tailored for versatility and performance. At the core of its specifications, the switch includes 48 fixed 10/100/1000 Mbps Ethernet ports, accommodating a wide array of devices and connections. For higher bandwidth requirements, it is equipped with 4 10 Gbps ports, enabling high-speed connectivity for uplinks or aggregation. Management and configuration are facilitated through a single RS-232 serial console port, and a USB port offers additional connectivity for storage or other peripherals. This model is designed with redundancy and reliability in mind, featuring dual power supplies and redundant fan units, ensuring uninterrupted operation and optimal cooling within a 1RU form factor. The switch boasts a switching capacity of 176 Gbps and a forwarding rate of 132 Mpps, supporting high-volume traffic without compromising performance. Support for jumbo frames up to 9216 bytes enhances the efficiency of large data transfers, while a capacity for 128,000 MAC addresses and 4096 VLANs allows for extensive network segmentation and management. The device supports 512 Spanning Tree Protocol (RSTP) instances and 64 Multiple Spanning Tree Protocol (MSTP) instances, facilitating robust network topology and redundancy configurations. Security and traffic management are robust, with 2000 ingress and 1000 egress Access Control List (ACL) entries. The routing table can accommodate 16,000 prefixes and host entries, along with 8000 multicast routes, ensuring comprehensive coverage and control over network traffic. The Cisco N3K-C3048TP-1GE supports up to 52 EtherChannels with a maximum of 16 ports per EtherChannel, allowing for flexible link aggregation and increased bandwidth. The shared buffer of 9 MB helps in managing traffic bursts, minimizing packet loss and ensuring smooth data flow. With a boot flash memory of 2 GB, the switch offers ample storage for the operating system and configurations. It operates efficiently, consuming 120 W of power and dissipating 409 BTU per hour, making it an energy-conscious choice for data centers.
  • Dimensions: 1.72 x 17.3 x 19.7 inches, fitting seamlessly into standard racks.
  • Temperature Range: Operates between 0 °C and 40 °C, with a relative humidity tolerance of 10% to 85% (noncondensing), suitable for most data center environments.
  • Physical Interfaces: 48 Ethernet ports, 4 10 Gbps ports, 1 RS-232 console port, and 1 USB port, providing a versatile set of connectivity options.
In summary, the Cisco N3K-C3048TP-1GE switch combines high-density Ethernet connectivity, advanced features for network control and security, and efficient power usage within a compact and reliable hardware platform. This makes it an ideal choice for organizations seeking to enhance their network infrastructure with a focus on performance and resilience.
