Figure 2-12. The RLP Health Statistics Window

RLP Health statistics provide the following general usage information for all ports on the selected card:

Frames Received

The total number of frames received on all active serial

 

ports on the selected RLP, expressed as a rate

 

(frames/second).

Frames Transmitted

The total number of frames transmitted by all active

 

serial ports on the selected RLP, expressed as a rate

 

(frames/second).

Frames Rejected

The total number of frames rejected by all active serial

 

ports on the selected RLP, expressed as a rate

 

(frames/second). Each protocol handles rejected frames a

 

little differently; in general, however, frames are rejected

 

because the active protocol has detected an error in the

 

frame itself.

Frames Retransmitted

The total number of frames retransmitted by all active

 

serial ports on the selected RLP, expressed as a rate

 

(frames/second). Frames are typically retransmitted to

 

correct errors or if the receiving device was too busy to

 

receive the original frames; a high retransmit rate can

 

indicate a noisy transmission line. If this value is

 

consistently above zero and there are no other problems,

 

you may want to increase the value assigned to the

 

Retransmission Timer in the port database record. (See

 

your hardware documentation for more information.)

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.
