Introduction
The Cisco Network Processing Engine 400 (NPE-400) is a high-performance network processing engine designed for use in Cisco 7200 Series routers. The NPE-400 is a powerful and flexible platform that provides a wide range of features and capabilities to help organizations improve their network performance and efficiency. This review will evaluate the usability, performance, and design of the Cisco NPE-400, as well as its strengths and weaknesses, and provide a recommendation on its overall value.
User Experience
As a network processing engine, the Cisco NPE-400 is primarily used by IT professionals and network administrators. Users typically interact with the NPE-400 through the command-line interface (CLI) or a web-based graphical user interface (GUI) to configure and manage network resources. Overall, the user experience with the NPE-400 is highly dependent on the skill level and experience of the user.
In terms of usability and user-friendliness, the NPE-400 offers a range of features and capabilities that can be configured and managed through the CLI or GUI. However, for users who are not familiar with the Cisco IOS command-line interface or networking concepts, the learning curve can be steep. The web-based GUI offers a more intuitive interface for configuring and managing network resources, but it may not be as flexible or powerful as the CLI.
Performance and Functionality
The Cisco NPE-400 is a high-performance network processing engine that provides a range of features and capabilities for improving network performance and efficiency. The NPE-400 supports up to 4 million packets per second (pps) forwarding rate and up to 1 Gbps aggregate throughput, making it ideal for large-scale networks and high-bandwidth applications.
One of the key strengths of the NPE-400 is its flexibility and scalability. The NPE-400 supports a range of networking protocols and technologies, including IPv4, IPv6, Multiprotocol Label Switching (MPLS), Virtual Private Networks (VPNs), and Quality of Service (QoS). Additionally, the NPE-400 supports a range of interfaces, including Ethernet, Fast Ethernet, Gigabit Ethernet, and ATM.
However, the NPE-400 does have some weaknesses. For example, it does not support hardware-based encryption, which can limit its ability to secure network traffic. Additionally, the NPE-400 does not support certain advanced features, such as packet capture and analysis, which may be important for some network administrators.
Design and Aesthetics
The design of the NPE-400 is functional and utilitarian, with a standard card form factor that is compatible with Cisco 7200 Series routers. The front panel of the NPE-400 features a series of indicator lights for monitoring status and activity, as well as a console port for local management.
In terms of aesthetics, the NPE-400 is not particularly stylish or visually appealing, but this is not a major consideration for most network administrators. The focus of the NPE-400 is on performance and functionality, and its design reflects this priority.
