Configuring a Network Trunk

Pressing [G] will display a list of all CUGs configured for this port, along with their associated indices.

A network trunk is a link between SmartSwitch 1800/FRM/FRX nodes, over X.25. Other ports in the node can be assigned to a "trunk group," which will cause those ports to be disabled if the network trunk is not operational (and enabled when the trunk becomes operational). One network trunk in a node can be assigned to another network trunk's group; however, disabling/enabling a network trunk will not affect another network trunk in that trunk's group.

If Network Trunk is N, the rest of the above screen has no relevance.

You can add or delete one or more ports as described in menu entries B–E in Figure 8-3.To add or delete a range of sequentially numbered ports of the same port type, press [D] or [E] and enter (when prompted) the port type, first port, and last port. The screen will be re-displayed, with the Y/N status changed for each affected port.

Adding or deleting a range has no affect on any port types within that range other than the type specified.

To add or delete a single port, multiple ports that are not in sequence, or multiple ports of different types, press [B] or [C] and enter a port number. The screen will be re-dis- played, with the Y/N status changed for the port. Repeat this process for each port you want to add or delete.

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.
