SNA Status and Conﬁguration

BAGs regulate bandwidth usage by outgoing trafÞc on the physical link and can ensure that response time-sensitive trafÞc gets access to the available frame relay bandwidth. Up to 16 groups can be conÞgured through console management (refer to your FRX or SmartSwitch 1800 hardware documentation for more information).

NOTE

Bandwidth allocation groups cannot currently be conÞgured via SPMA; for more information on conÞguring these groups, see your FRX or SmartSwitch 1800 hardware documentation.

Priority

This Þeld prioritizes the interface for trafÞc within the device; the higher the number, the higher the priority. This priority has no effect on trafÞc exiting the device. Priorities are conÞgured on all logical interfaces that use a physical frame relay port. The FRX or SmartSwitch 1800 processor uses these priorities to help determine the order in which it will process protocols. The default value for this parameter is 0.

When conÞguring priorities, be sure to consider the types of trafÞc being routed on other

TIP connections in the node.

If Yes is selected, this parameter prevents the FRX or SmartSwitch 1800 from returning an XID (Exchange IdentiÞcation) in response to a null XID. This might be desirable if the remote TPAD is not running PU 2.1 It should be noted that even if an XID is sent, an SNRM (Set Normal Response Mode) immediately follows, so the connection will be established. The default value for this parameter is No.

Changing SDLC PU LLC2 Values

To edit the SDLC PU LLC2 values:

1.If you wish to modify an existing entry, be sure that entry is highlighted in the list box portion of the window.

2.Enter and/or edit the values displayed in the text boxes, as desired. (Remember, some values which are settable from this window must mirror values conﬁgured elsewhere; be sure these values match as necessary.)

3.Click on to create a new entry, or on to edit the entry currently selected in the list box.

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.
