Network Mask

is used during routing to determine the portion of the address associated with the network and subnetwork (if any). All bits associated with the network/subnet should be set to 1, and must be contiguous.

Descriptions of Parameters Specific to X.25 Interfaces

Destination IP Address

is the IP address of the end-to-end receiver for point-to-point X.25 connections. The valid range of values guarantees that you cannot configure all 0s or all 1s for a network ID, node ID, or subnet ID. (See page 14-1.)

Unnumbered Interface

allows the point-to-point frame relay interface to be configured without specifying a source IP address. If Y, the address of the lowest IP interface number (not the lowest address, but the number, in the range 0–256 , that identifies the interface) in the Smart- Switch is used as a default source IP address. (It does not matter what type that interface is.) All un-numbered interfaces on the SmartSwitch use the same default address.

If a new interface with a lower number is added, that interface’s address will become the new default source IP address, but only after the next IPL of the SmartSwitch.

Naturally, this feature works only if there is at least one numbered interface in the device. If there are none, all un-numbered interfaces remain disabled. Once a num- bered interface is added, all un-numbered interfaces will become active.

Source IP Address

is the IP address of the end-to-end sender. The valid range of values guarantees that you cannot configure all 0s or all 1s for a network ID, node ID, or subnet ID. (See page 14-1.)

Network Mask

is used during routing to determine the portion of the address associated with the network and subnetwork (if any). All bits associated with the network/subnet should be set to 1, and must be contiguous.

Source Subscriber

is a subscriber ID associated with the source IP interface port. (The port is the first Routing Path configured in the SVC Subscriber record.)

Destination Subscriber

is a subscriber ID associated with the destination IP interface port. (The port is the first Routing Path configured in the SVC Subscriber record.)

SVC Retry Timer

is the frequency with which calls will be placed to try to establish an X.25 connection.

SVC Idle Timer

is a period that IP remains active with no traffic before the X.25 connection is cleared.

Max VCs to Establish

is the number of virtual circuits over which IP traffic will be transmitted in parallel.

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.
