PVC Connection

simply states whether this interface is a PVC.

Descriptions of Parameters Specific to LAN Interfaces

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.

Broadcast Address

is used to send to all LAN hosts on the network.

Proxy ARP Enabled

Determines whether Proxy ARP will be supported on the Ethernet interface. Proxy ARP allows the SmartSwitch to respond to ARP requests on one subnet for a host on another subnet. This lets the device that sent the ARP request think the SmartSwitch is the destination host.

If an ARP request is received, the IP function in the SmartSwitch 1800 checks the address against the Source IP Address configured on the IP interface. Then:

●If the addresses match, a reply will be sent.

●If the addresses do not match, and Proxy ARP is not enabled, no response will be sent .

●If the addresses do not match, and Proxy ARP is enabled, the IP function will check to see if the SmartSwitch has a route to the host or the host’s network. If there is a route, and the route is reachable, and the route is not on the same interface on which the ARP request was received, an ARP response will be sent.

Secondary Address Parameters

Seq

is simply a sequence number to identify the entry.

Sec. IP Addr

specifies a secondary IP address. 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.)

NetMask

is the sub-network mask for the secondary IP address. The mask is used during routing to determine the portion of the address associated with the sub-network. All network bits are set to 1 and must be contiguous.

Bcast Addr

is the broadcast address associated with the secondary IP address. This address is used to send to all LAN hosts on the sub-network.

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.
