Configuring Async Ports

Introduction

The integral Async PAD function in the SmartSwitch 1800 allows asynchronous devices to connect to a frame relay or X.25 network.

Required Configuration

To run a port as an integral async PAD in a SmartSwitch 1800, make sure the fol- lowing are properly configured:

●Node parameters (Chapter 4). This is general configuration that must be done no matter which protocols will be run in the node.

●Async PAD Profiles (page 12-2), which define the operation of the attached devices.

●Login parameters (page 12-7), which define passwords to be used when logging into the SmartSwitch.

●Loaded protocols (Chapter 5): Async, plus frame relay or X.25.

●Async port(s) (page 12-8), plus frame relay (Chapter 7) or X.25 (Chapter 8) port(s) that will connect to the user device(s) and network.

●Subscriber IDs (page 12-15), which identifiy user devices to each other and the SmartSwitch.

●Abbreviated address(es) (page 12-17), if desired. This feature (described later in this chapter) allows short "nicknames" to be assigned to subscriber addresses, to ease entry of addresses.

●PVC connections (page 12-18), which create "permanent" connections between two ports in the node. A PVC can be created between two async ports or between an async port and an X.25 port.

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.
