1The default value of the network mask will be configured automatically, to reflect the appropriate address class, after an IP address is specified. ( Network Mask is determined by Source IP Address, and NetMask is determined by Sec. IP Addr . ) If the interface is configured as unnumbered (and, therefore, no Source IP Address is configured), the default value of Network Maskwill be taken from the numbered interface that is assigned.

If an IP address (Source IP Address/Sec. IP Addr) is specified/ changed, the network mask will automatically change to default values appropriate for the new address. For this reason, configure the IP address first, then the mask.

2The default value of the broadcast address will be configured automatically after an IP address or a network mask is specified. The value will be the dotted decimal notation result of "ANDing" the binary versions of the IP address and the network mask, then

filling in the remaining bits with 1s. (Broadcast Address is associated with Source IP Address and Network Mask, while Bcast Addr is associated with Sec. IP Addr and NetMask.)

If the (Source IP Address/Sec. IP Addr) or Network Mask/Netmask

is specified/changed, the associated broadcast address will automatically change to default values appropriate for the new address. For this reason, configure the IP address first, then the mask, then the broadcast address.

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.
