1Y for new interfaces, N for interfaces already configured when the current release of SmartSwitch 1800 software is installed.

2255.255.255.255 is valid only on a point-to-point interface.

3The default value of Network Mask will be configured automatically, to reflect the appropriate address class, after the Source IP Address is specified.. If the interface is configured as unnumbered (and, therefore, no Source IP Address is configured), the default value of Network Mask will be taken from the numbered interface that is assigned.

If a Source IP Address is specified/changed, the Network Mask will automatically change to a default value appropriate for the new address. For this reason, configure the Source

IP Address first, then the Network Mask.

4These addresses must also be configured in Subscriber records (described on page 8-20), and cannot contain wildcards. In the record for the Source Subscriber, do not configure any Routing Path. In the record for the Destination Subscriber, configure 1st Routing Path as the node, RLP (only if FRX6000 or FRM), and X.25 port that will be used for the physical interface. (On an FRX6000 or FRM, that RLP does not need to be the same one that has IP installed.)

1800 specifications

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.
