IPX Interface Configuration

time is used to calculate the least-cost path during routing. If WAN Enabled is set to Yes (see above), the Transport Time selected here will be overridden by the value calculated by IPXWAN.

NetBIOS Hops

This is the maximum number of network hops allowed for routing a Novell-encapsulated NetBIOS frame. Each router in a packetÕs path to the destination network is one hop. Frames exceeding this value will be discarded. The default value for this parameter is 8.

Periodic SAP Timer

If Periodic SAP Enabled is set to Yes (see above), then this Þeld speciÞes the interval (in seconds) between the periodic IPX Service Advertising Protocol (SAP) broadcasts from this interface. If this is set to greater than 0, the SAP Age Timer (see below) must be three times longer than the Periodic SAP Timer. The default value for this parameter is 60.

SAP Age Timer

If SAP Enabled is set to Yes (see above), this timer is used to delete route entries in the server information table. The timer starts each time SAP creates or updates an entry, or an entry is referenced for forwarding. This Þeld speciÞes the amount of time (in seconds) that will elapse before the timer expires and the router assumes that the entry is no longer valid (due to hardware failure, power outage, etc.), and the entry will be deleted from the table. SAP will then send a broadcast message indicating that the server is down. If the value for the Periodic SAP Timer is set to greater than 0, the SAP Age Timer must be three times longer than the Periodic SAP Timer. A value of 0 for the SAP Age Timer disables aging. The default value for this parameter is 180.

Periodic RIP Timer

If Periodic RIP Enabled is set to Yes (see above), then this Þeld speciÞes the interval (in seconds) between the periodic IPX Routing Information Protocol (RIP) broadcasts from this interface. If this is set to greater than 0, the RIP Age Timer (see below) must be three times longer than the Periodic RIP Timer. The default value for this parameter is 60.

RIP Age Timer

If RIP Enabled is set to Yes (see above), this timer is used to delete route entries in the routing information table. The timer starts each time an entry is created, updated, or referenced for forwarding by RIP. This Þeld speciÞes the amount of time (in seconds) that will elapse before the timer expires and the router assumes that the entry is no longer valid (due to hardware failure, power outage, etc.) and the entry will be deleted from the table. If the value for the Periodic RIP Timer is set to greater than 0, the RIP Age Timer must be three times longer than the Periodic RIP Timer. A value of 0 for the RIP Age Timer disables aging. The default value for this parameter is 180.

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.
