About FRX and SmartSwitch 1800 Bridging support; conﬁguring device-level bridging parameters; conﬁguring bridge ports on frame relay and LAN interfaces

The FRX and SmartSwitch 1800 devices support bridging of LAN trafÞc over Frame Relay. This bridging support includes:

¥encapsulation of Ethernet and Token Ring trafÞc (per RFC 1490) for transmission over Frame Relay

¥Transparent Spanning Tree (802.1d) bridging

¥compatibility with Source Route Bridging environments

¥translational bridging between Ethernet and Token Ring LANs

¥bridging of IP and IPX trafÞc.

Bridging is supported on Ethernet, Token Ring, and Frame Relay interfaces.

Conﬁguring Device-Level Bridging Parameters

If the FRX4000, FRX6000, or SmartSwitch 1800 is going to support one or more bridge ports (interfaces), certain device-level bridging parameters must be conÞgured to deÞne bridge operation.

Using the Bridge ConÞguration window, you can conÞgure the device-level bridging parameters. To access the window:

1.Click on to display the Device menu.

2.Drag down to Bridge Conﬁguration, and release. The Bridge Conﬁguration window, Figure 11-1, will appear.

1800, FRX4000, FRX6000 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.
