Secondary Alarm Output ID

is used for a collecting node to send alarms to a second location other than that spec- ified by the Primary Alarm Output ID. This parameter has no function on non-collecting nodes.

Secondary Alarm Output Pwd

is a password that will be used if the Secondary Alarm Output ID is an address that is also associated with a password. If so, both passwords must match.

Collecting Node

is a SmartSwitch 1800 or other Cabletron frame relay access device to which alarms are sent from other Cabletron frame relay access devices. Any SmartSwitch 1800, 9W004, FRX4000, or FRX6000 can be a collecting node; which nodes send their alarms to a collecting node is determined by the Primary Alarm Output IDs and pass- words of the other nodes; these must match the Collecting Node ID and password of their collecting node.

The number of nodes that can report to a collecting node depends on the number of connections that can exist on the collecting node. (A SmartSwitch 1800 supports up to 512 connections.) A connection on a collecting node is required for each reporting device.

Do not configure a collecting node to send its alarms to another collecting node. The alarms will be ignored, due to a format mis- match.

Max Congestion

is a percentage of the SmartSwitch 1800 alarm buffer. If this level is exceeded, no more alarms will be put into the buffer until it has reached the specified gestion. (See that entry below and "Alarm Buffer" on page 22-2.)

Min Congestion

is a percentage of the SmartSwitch 1800 alarm buffer. As long as the percent of the buffer that is full is below this level, alarms will always be placed into the buffer. (See "Alarm Buffer" on page 22-2.)

Periodic Status Timer

sets the frequency with which the SmartSwitch will send a "heartbeat" alarm message containing the date and time. The heartbeat serves as a verification that the Smart- Switch is operational.

Line Idle Timer

is a period that an SVC alarm connection will remain active after an alarm message is sent. If no alarm is generated during this time, the alarm connection is cleared. The

(see that entry) determines the frequency with which routine status messages for this SmartSwitch will be sent. On a reporting (non-collecting) node, it is generally preferable to set the Line Idle Timer to a period longer than the Periodic Status Timer, to give the system a chance to update itself. The timer is usually set to 0 on a collecting node.

The Line Idle Timeris also affected by the value of Max Congestion (described on page 4-5).

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.
