116, 32, 64 ,128, 256, 512, 1024, 2048, or 4096. Cannot be greater than the smaller Maximum Packet Size specified in the port records for both ends of the connection.

2Cannot be greater than the smaller Maximum Window Size specified in the Port records for both ends of the connection.

Connection Priority

prioritizes this connection for intra-nodal traffic; the higher the number, the higher the priority. (This priority has no effect on traffic exiting a node.)

Priorities are configured on all logical interfaces that use a physical frame relay port. The device processor in the node uses these priorities to help determine the order in which it will process protocols.

When configuring priorities, be careful to consider the types of traffic being routed on other connections in the node.

Subscriber Name

identifies the subscriber to the console operator. The software does not use this infor- mation.

Logical Channel

is a logical link between the node and the subscriber.

Port

specifies the port at each end of the PVC.

Packet Size

allows setting a packet size for each end of the PVC. Generally the same packet size will be configured in the port record at each end, as well as in the PVC record.

Window Size

allows setting a window size for each end of the PVC. Generally the same window size will be configured in the port record at each end, as well as in the PVC record.

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.
