Using the TSX-1620 Bridge View

2.In the Modify Range section of the Forwarding Thresholds window, you can edit the line that displays the high end of the Low and Mid ranges, or you can use the slide bars to specify the thresholds. You can also assign a color to each of the three ranges. The Bridge Port boxes on the Bridge Traffic View will be colored according to the settings made here (i.e., if you assign the color red to the High traffic range, then a Bridge Port box will be colored red when its traffic range is High). To set the high end of the Low and Mid ranges, and assign color codes to all three ranges:

a.Change the upper limit of the Low and Mid traffic ranges by highlighting the value, typing the new value, and pressing Enter or Return. You may also change the value by moving the slide bar next to the value you wish to change until the desired range is reached.

b.By default, bridge ports are color coded in the Bridge Traffic View according to their traffic level: Low range is green; Mid range is yellow; High range is red. To assign color codes to the three traffic ranges, click on the Low, Mid, or High buttons to the left of the range fields, drag to highlight the desired color, and release. The selected color will be displayed on the button, and will be used in the Bridge Port boxes when the color’s corresponding range is reached.

3.In the Notification Options section, you can enable/disable threshold event logging, enable/disable the Bridge Port box colors, and assign threshold events (send mail or execute a program) to the different (or to all) threshold ranges. To do so:

a.To disable threshold event logging, deselect the Log Changes in State checkbox. By default, all threshold events are logged. For more information about the Forwarding Log, see Viewing the Forwarding Log on page 3-37.

b.To enable/disable the colors, click button 1 on the Color box. When colors are disabled, the Bridge Port box colors in the Bridge Traffic View remain as they were when the colors were last enabled.

c.To send mail or execute a program when a threshold range is reached, first click theThreshold Range button to which you want to apply the threshold event. To send mail for a threshold event, select the Send Mail box and enter the name of a registered mail user. To have a threshold event launch a program, select the Execute Program (Args) box and enter the name of an executable file, including required arguments.

4.Notification Conditions make your Notification Options subject to defined conditions:

a.If you check the In—Out—Inbox, notification takes place when the threshold passes from one range to another and then back. The number in the Delay box specifies the number of times this transition is to take place before notification is launched. TheCurrent box counts down the transitions.

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.
