Enabling and Disabling a Source Routing Bridge Port

With Source Routing bridging, you can disable all traffic through a particular bridge port, or only traffic that would otherwise be forwarded to a specific port. For example, you can disable all traffic that would be forwarded from port 2 to port 4, but allow traffic to be forwarded from port 2 to ports 1 and 3.

The Enable/Disable Source Routing window lets you enable or disable Source Routing traffic between the selected port (the port you used to open the window) and any other bridge port.

To enable or disable a Source Routing bridge port:

1.In the Bridge Traffic View, display the Port menu by clicking mouse button 3 in the Bridge Port box that represents the network that you want to enable or disable.

2.In the Port menu, click on Enable or Disable, drag right to Source Routing, and release to open the Enable/Disable Source Routing window.

TSX-1620 specifications

The Cabletron Systems TSX-1620 is a pioneering piece of network hardware that played a significant role in the evolution of networking technologies during the 1990s. This well-engineered device is primarily recognized as a multi-port Ethernet switch that was designed to provide high-speed, reliable connectivity for local area networks (LANs). As organizations increasingly demanded robust performance and enhanced network capabilities, the TSX-1620 emerged as a powerful solution to address these needs.

One of the key features of the TSX-1620 is its support for both 10Base-T and 100Base-T standards, catering to both standard Ethernet and Fast Ethernet connections. This versatility allowed businesses to easily transition from older Ethernet systems to newer, faster specifications without replacing their entire infrastructure. The switch could intelligently manage traffic between devices, minimizing collisions and ensuring that data packets were transmitted efficiently.

The architecture of the TSX-1620 includes support for various advanced technologies that enhance network performance. Its store-and-forward switching capability improves data integrity by checking packets for errors before forwarding them to their destination. This process reduces the risk of corrupted data affecting network performance, making it especially valuable for mission-critical applications.

Another notable feature is its robust security tools. The TSX-1620 incorporates VLAN (Virtual Local Area Network) support, enabling network administrators to segment traffic and improve security across different departments or user groups. This not only mitigates the risk associated with unauthorized access but also optimizes network traffic by confining broadcasts to designated VLANs.

Scalability is a prominent characteristic of the TSX-1620. With ports available for expansion, organizations could easily increase their network capacity as their needs grew. This feature promoted long-term investment in network infrastructure, allowing businesses to adapt quickly to changing demands without incurring substantial costs.

Reliability is paramount in networking equipment, and the TSX-1620 does not disappoint. Engineered with high-quality components, this switch was built to operate efficiently in a variety of environments while maintaining stable performance. Its design ensures a cooling mechanism that minimizes overheating, thereby prolonging its operational lifespan.

In summary, the Cabletron Systems TSX-1620 represents a significant advancement in network switch technology during its era. Its combination of speed, versatility, security features, and robust architecture made it a valuable asset for organizations seeking to enhance their networking capabilities and prepare for the future.
