IP Interface Configuration

Source Address

This is the IP address of the end-to-end sender (the IP interface). The valid range of values (1.0.0.0 to 223.255.255.255) guarantees that you cannot conÞgure all 0s or all 1s for a network ID, node ID, or subnet ID. If the interface is conÞgured as an Unnumbered Interface (see below), you will not enter a source address here.

Destination Address

This parameter is only conÞgurable when the Interface Type is X.25, or when the Interface Type is Frame Relay and the Inverse ARP parameter is Disabled. It is the IP address of the end-to-end receiver for point-to-point connections. The valid range of values (1.0.0.0 to 223.255.255.255) guarantees that you cannot conÞgure all 0s or all 1s for a network ID, node ID, or subnet ID.

Broadcast Address

If you speciÞed a LAN Interface Type, use this Þeld to designate the address used to send broadcast messages to all LAN hosts on the network. The default value of the broadcast address will be conÞgured automatically after a Source Address or Network Mask is speciÞed (see above). The value will be the dotted decimal notation result of ÒANDingÓ the binary versions of the Source Address and the Network Mask, then Þlling in the remaining bits with 1s.

If the Source Address or Network Mask is changed, the associated broadcast address will automatically change to the default value appropriate for the new address. For this reason, conÞgure the Source Address Þrst, then the Network Mask, then the Broadcast Address.

LAN Card

If you speciÞed a LAN Interface Type, this number identiÞes the LAN card that contains the IP interface. Enter 0 for the FRX4000 or SmartSwitch 1800; 0 or 1 for the FRX6000.

Source Subscriber

This parameter is only conÞgurable if you have selected X.25 as your Interface Type. This is the Subscriber ID associated with the source IP interface port. A subscriber ID is an address of up to 15 digits. This address must also be conÞgured in the Subscriber Table (see Chapter 4, ConÞguring the Subscriber Table), and cannot contain wildcards. When conÞguring the Subscriber Table for the source subscriber, do not conÞgure any routing path in the Routing Table.

Destination Subscriber

This parameter is only conÞgurable if you have selected X.25 as your Interface Type. This is the Subscriber ID associated with the destination IP interface port. A subscriber ID is an address of up to 15 digits. This address must also be conÞgured in the Subscriber Table (see Chapter 4, ConÞguring the Subscriber Table), and cannot contain wildcards. When conÞguring the Subscriber Table for the destination subscriber, conÞgure the Þrst routing path as the RLP and X.25 port that will be used for the physical interface. (On an FRX6000, that RLP does not need to be the same one that has IP installed.)

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.
