SNA Status and Configuration

The SDLC Link Station ConÞguration window allows you to conÞgure the following parameters:

Address

This is the SDLC PU Station Address, 00 - ff, that identiÞes the PU you are conÞguring. It must match the ADDR parameter set in the macro PU in the VTAM conÞguration.

Name

Enter the name of the local SDLC link station.

Max RX PDU Size

This is the maximum PDU size that the local link station can receive from the adjacent link station. This value is sent in the XID to the ALS and includes the Transmission Header (TH) and the Request Header (RH).

Max TX PDU Size

This is the maximum PDU size the local link station can send to the adjacent link station before having received any XID from the ALS. This value includes the Transmission Header (TH) and the Request Header (RH).

Reply Timeout

This Þeld speciÞes a reply timeout (in 1/100ths of a second) for an SDLC link station. If the link station does not receive a response to a poll or message before the speciÞed time expires, the appropriate error recovery will be initiated. The default value for this parameter is 100.

Max Rx UnACK I-Frames

This Þeld speciÞes the maximum number of unacknowledged I-frames an SDLC link station may receive. The default value for this parameter is 7.

Max Tx UnACK I-Frames

This Þeld speciÞes the maximum number of consecutive I-frames an SDLC link station may send without an acknowledgment. The default value for this parameter is 1.

Retries in Sequence

This is the number of retries in a retry sequence for the local SDLC link station. A retry sequence is a series of retransmitted frames (data or control) for which no positive acknowledgment is received. The default value for this parameter is 15.

Retry Sequence Interval

This is the interval (in 1/100ths of a second) between retry sequences for the local SDLC link station if multiple retry sequences are speciÞed. The default value for this parameter is 0.

7-16

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.
