Outgoing Rate Control

This parameter determines whether the rate parameters (CIR, BC, and BE) assigned to the physical link and/or its virtual circuits will be enforced: Yes or No. Choosing not to enforce rate parameters allows trafÞc rates to exceed those conÞgured for the selected circuits, possibly impacting performance. Exceeding CIR may also lead to additional charges from your frame relay provider.

Bandwidth Allocation

If you have conÞgured Bandwidth Allocation Groups for the selected port (or any logical ports conÞgured for that port), you can use this Þeld to enable (Yes) or disable (No) any conÞgured bandwidth allocation parameters. BAGs regulate bandwidth usage by outgoing trafÞc on the physical link and can ensure that response time-sensitive trafÞc gets access to the available frame relay bandwidth. Up to 16 groups can be deÞned and 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.

Backup Use Only

This Þeld determines whether all DLCIs on the port will be reserved exclusively as backups for other DLCIs in the same node. If you select Yes, this port will only provide backup DLCIs; if you select No, it can provide backup and primary DLCIs.

If you conÞgure the port for backup use only, make sure no DLCIs on the port have been conÞgured on an IP, IPX, or LLC2 interface. If this parameter is set to Yes, the port will remain disabled until needed for backup.

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.
