SNA Status and Configuration

The list box at the top of the window displays any connections that have already been conÞgured.The Þelds and buttons in the lower portion of the window allow you to add new entries, and modify or delete existing ones.

The Connections Table allows you to conÞgure the following parameters:

Sequence

This is simply a sequence number to allow selection of a line in the display.

HSAP

This is the host service access point (HSAP) address used to connect to the host. This must match the SSAP (source SAP) in a frame received from the local LAN or the DSAP (destination SAP) in a frame from the remote link station.

Local Subscriber ID

This is the subscriber address assigned to the local end of the SNA connection. If you are conÞguring an LLC2-to-SDLC link, this address must match the Remote Subscriber ID parameter conÞgured in the SDLC Physical Unit Subscriber Table (see SDLC PU ConÞguration, page 7-7). If you are conÞguring an LLC2-to-LLC2 connection, this address must match the Remote Subscriber ID in the remote nodesÕs Connections Table.

The Local Subscriber ID can be up to 15 digits long, and must begin with all of the actual Routing Subscriber ID conÞgured in the SNA/LLC2 Host Table. The Local Subscriber ID can contain an asterisk as the Þnal digit; if so, the asterisk will not be a ÒuniversalÓ wildcard, but instead will include the range 000-511, or 00-99 if 13 digits precede the wildcard, or 0-9 if 14 digits precede the wildcard.

Remote Subscriber ID

This is the subscriber address assigned to the remote end of the SNA connection. If you are conÞguring an LLC2-to-SDLC link, this address must match the Local Subscriber ID parameter conÞgured in the SDLC Physical Unit Subscriber Table (see SDLC PU ConÞguration, page 7-7). If you are conÞguring an LLC2-to-LLC2 connection, this address must match the Local Subscriber ID in the remote nodesÕs Connections Table.

The Remote Subscriber ID can be up to 15 digits long. It can contain an asterisk as the Þnal digit; if so, the asterisk will not be a ÒuniversalÓ wildcard, but instead will include the range 000-511, or 00-99 if 13 digits precede the wildcard, or 0-9 if 14 digits precede the wildcard.

Type

This read-only parameter is relevant only in an Originated Connections Table, and is always LLC2.

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.
