Serialization Enabled

determines whether NetWare file server serialization security frames will be for- warded on the interface. These broadcast frames are used by Novell to hold infor- mation regarding the licensing of the file server executables.

Disabling serialization allows filtering of these broadcasts to reduce WAN traffic, and is not intended to interfere with copyright-protection mechanisms.

Watchdog Spoofing Enabled

determines whether this interface will be used by the local node to respond to "keep- alive" messages on behalf of the client workstations. Novell servers periodically issue these messages to all clients, to determine whether each client is still available.

Descriptions of Parameters Specific to Frame Relay Interfaces

IPXWAN Enabled

determines whether Novell's IPXWAN protocol will be used on the interface. IPXWAN specifies a method for IPX routers to communicate across WAN links. The SmartSwitch 1800 implements IPXWAN running over RFC 1490-compliant frame relay and RFC1356-compliant X.25.

Source Card/Port/DLCI

identifies the location of this end of the frame relay IPX interface. Note that there is no Source Card, but the software code is shared with the Netlink FRX6000, which does have a card.

Make sure the physical frame relay port is not reserved for backup DLCIs (as determined by the For Backup Use Only? parameter in the port record).

Also make sure the DLCI is not part of a frame relay DLCI backup group or frame relay PVC.

Descriptions of Parameters Specific to X.25 Interfaces

IPXWAN Enabled

Source Subscriber

is a subscriber ID that defines an IPX interface in the node, by associating itself with port 66 (a number reserved for the IPX interface). (See the footnote following Table 15-8.)

Destination Subscriber

is a subscriber ID associated with the physical X.25 port that will be used for the IPX interface. (See the footnote following Table 15-8.)

SVC Retry Timer

is the frequency with which calls will be placed to try to establish a connection.

Configuring IPX

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.
