Using the TSX-1620 Bridge View

Designated Bridge

Displays the MAC address and priority component of the Bridge ID for the bridge that is believed to be the Designated Bridge for the network segment associated with this port.

The Designated Bridge ID, along with the Designated Port and Port Identifier parameters for the port, is used to determine whether this port should be the Designated Port for the network segment to which it is attached.

Designated Port

The Port ID of the port on the Designated Bridge for this port’s segment. The Designated Port is the bridge port that offers the lowest path cost to the Root Bridge.

Forward Transitions

The number of times this port has moved from the Learning state to the

Forwarding state since the device was started or since it was last reset.

Changing a Port’s STA Parameters

To change a port’s Priority or Path Cost:

1.In the scroll list, click mouse button 1 on the port you want to change (use the scroll bar if necessary to display the desired port). You can only select one port at a time. The highlighted port’s Spanning Tree parameters appear in the boxes below the list.

2.Highlight and edit the Priority and Path Cost boxes as required. After you type in the new value in a box, press Enter or Return on the keyboard.

The Source Routing Configuration Window

The Source Routing Configuration window allows you to view, set, and change Source Routing configuration options for ports on the TSX-1620. Using this window, you can assign logical ring numbers to the TSX-1620’s physical ports via the Local Segment field. If you assign the same local segment number to multiple physical ports, the TSX-1620 will treat all segments attached to those ports as if they were on the same physical ring.

To open the Source Routing Configuration window from the Bridge Traffic View:

1.Display the Device menu by clicking on the Front Panel button.

2.Drag down to SR Configuration. or

1.In the Bridge Traffic View, click mouse button 3 on a port to display the Port menu underage down to SR Configuration.

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.
