Bridge Configuration

Bandwidth Allocation Group

This parameter assigns the bridge port to one of 16 Bandwidth Allocation Groups (BAG).

BAGs regulate bandwidth usage by outgoing trafÞc on the physical link and can ensure that response time-sensitive trafÞc get access to the available frame relay bandwidth. Up to 16 groups can be conÞgured through console management (refer to your FRX or SmartSwitch 1800 hardware documentation for more information).

NOTE

Bandwidth allocation groups cannot currently be conÞgured via SPMA; for more information on conÞguring these groups, see your FRX or SmartSwitch 1800 hardware documentation.

Format

This Þeld speciÞes the RFC 1490 encapsulation method that will be used for bridged trafÞc. Selecting Tb 8023 will add an Ethernet header to the frame; selecting Srb 8025 will add a Token Ring header to the frame; selecting Native LLC2 results is no MAC address header being added to the frame. If Native LLC2 is selected, the interface can only be used for terminated LLC2 trafÞc. The default value for this parameter is LLC2.

Session Type

This Þeld is conÞgurable only if you have selected Native LLC2 as your RFC 1490 encapsulation method in the Format Þeld (see above). For Session Type, if you select Originated, then LLC2 connections from the conÞgured Host MAC Address (see below) can use this interface. If you select Terminated, then connections to the conÞgured Host MAC address can use this interface. The default value for this parameter is Originated.

Host MAC Address

This Þeld is conÞgurable only if you have selected Native LLC2 as your RFC 1490 encapsulation method in the Format Þeld (see above). Enter the MAC address of the LLC2 host or workstation to which the remote LAN device needs to connect. This MAC address will match the address of the LLC2 host in the SNA/LLC2 Host Table (see Chapter 7 SNA Status and ConÞguration, for more information on conÞguring LLC2 hosts).

LAN ID

This Þeld is conÞgurable only if you have selected Srb 8025 (Token Ring) as your RFC 1490 encapsulation method in the Format Þeld (see above).This ID is only used in an 802.5 Source Route environment and is normally assigned by a system administrator. It identiÞes the ring number used by the frame relay-compliant source route bridge at the other end of the frame relay PVC.

Each LAN ID must be unique among all LAN IDs throughout the network on which this device will operate.

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.
