Product Review

The Cisco N55-DL2 module offers enhanced data networking capabilities when integrated with the Cisco Nexus 5548 Switch, ensuring efficient handling of network traffic. However, its compatibility is limited to the Nexus 5548, restricting its use in diverse network environments. Additionally, it requires a significant investment, potentially impacting budget allocations for broader network upgrades or expansions.


The Cisco N55-DL2 is a Layer 2 Daughter Card designed to enhance the capabilities of the Cisco Nexus 5548 Switch, focusing on data networking applications. This daughter card is engineered to provide additional features and improve the operational efficiency of the Nexus 5548, making it an essential component for network administrators seeking to optimize their data center's performance. At its core, the N55-DL2 expands the switching capabilities of the Nexus 5548 by adding 32 ports of 1/10GbE (Gigabit Ethernet), thereby increasing the total available bandwidth and allowing for a higher number of connected devices. This expansion is crucial for environments where data throughput and connectivity are vital, supporting a wide range of applications from high-performance computing to cloud services. The hardware specifications of the N55-DL2 include:
  • Compatibility with the Cisco Nexus 5548 Switch, ensuring seamless integration and performance optimization.
  • 32 additional 1/10GbE ports, significantly increasing network scalability and flexibility.
  • Layer 2 hardware support, offering advanced features such as VLANs, Spanning Tree Protocol, and port aggregation to enhance network efficiency and security.
This daughter card also supports FCoE (Fibre Channel over Ethernet), enabling the convergence of data and storage networks. This feature simplifies the network architecture, reduces cable complexity, and lowers overall costs by allowing both IP network traffic and storage traffic to share the same Ethernet infrastructure. The N55-DL2's design focuses on performance and reliability. It is built to handle high traffic volumes with low latency, ensuring that data flows smoothly and efficiently across the network. This is particularly important in data centers where time-sensitive applications such as VoIP (Voice over IP) and streaming services require consistent and reliable data delivery. Energy efficiency is another key aspect of the N55-DL2's design. It incorporates features that reduce power consumption, such as automatic port shutdown for inactive ports and support for Energy Efficient Ethernet (EEE), which reduces power usage during periods of low data activity. These features not only contribute to lower operating costs but also help organizations meet their environmental and sustainability goals. In terms of security, the N55-DL2 provides a range of features to protect the network. These include access control lists (ACLs), port security, and DHCP snooping. These features are essential for preventing unauthorized access, ensuring that only trusted devices can connect to the network and protecting against various security threats. The Cisco N55-DL2 is designed for easy installation and integration into existing networks, offering a plug-and-play solution that minimizes downtime and simplifies the upgrade process. Its compatibility with the Nexus 5548 Switch ensures that network administrators can leverage the enhanced capabilities of the daughter card without the need for extensive reconfiguration or hardware modifications. In summary, the Cisco N55-DL2 Layer 2 Daughter Card is a critical component for expanding the capabilities of the Cisco Nexus 5548 Switch. Its additional ports, support for advanced networking features, and focus on performance, reliability, and security make it an ideal choice for data centers looking to optimize their data networking infrastructure.
