Event Generation

As soon as a message-generating event occurs, a Call Request is automatically sent to the Primary Alarm Output ID, and the Secondary Alarm Output ID if configured. (The event is stored in the originating node's buffer until the event connection is activated.) All events are transmitted in raw data format to the collecting node, which constructs event messages and sends them to the display device(s).

An internal timer limits the time events are kept in the system buffer if the system fails to bring the event connection up. If the timer expires, the buffer is cleared. The event connection remains active until the event system detects that there are no events occurring during the time period set for the Line Idle Timer. After the event connection is cleared, the event system will repeat the above procedures if any events occur.

Displaying Events

To display any local events on the screen as they occur, press [D] at the Main Menu. Event messages will continue to be sent to any destinations specified by the param- eters described earlier in this chapter.

While this feature is activated, you cannot perform other operations on the screen. Also, if the Primary Alarm Output device is unreachable, no local events will be displayed.

A display at a collecting node looks like the example shown below. (A display at a sending node will show only that node's events.)

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.
