IP Interface Configuration

This function will only work if there is at least one numbered interface in the device. If there isnÕt one, all unnumbered interfaces will remain disabled until a numbered interface is added.

If you have upgraded your Þrmware to version 4.0, then the default value for IP interfaces that have already been conÞgured is No. If you are adding a new interface, the default value is Yes. If you select No, you must enter a Source Address (see deÞnition above).

Configuring IP Interface Secondary Addresses

If you have selected a LAN interface as your Interface Type in the IP Interface ConÞguration window, you can use the Secondary button at the bottom of the window to access the IP Interface Secondary Address ConÞguration window.

This window allows you to conÞgure up to 15 secondary IP addresses on a LAN interface, providing support for multiple IP subnets on the same physical LAN segment.

To access the IP Interface Secondary Address ConÞguration window, click on the Secondary button at the bottom of the IP Interface ConÞguration window. The IP Interface Secondary Address ConÞguration window, Figure 9-3, will appear.

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
