Using the TSX-1620 Hub View

Monitoring Device Performance

The information displayed in the Hub View can give you a quick summary of device activity, status, and configuration. SPMA can also provide further details about hub performance via its four-level menu structure. The Device, Module, Interface/Bridge and Bridge Port menus give you control over the device at four levels for both the Interface and Bridge application displays and give you access to the tools, menus, and windows that let you monitor specific aspects of device performance, change display options, and set TSX-1620 operating and notification parameters. See Figure 2-5and Figure 2-6to view the different menus and their contents.

Port Display Form

You can change the type of information displayed for each port by using the Port Display Form option on the Interface or Bridge menus. Remember that you need to change the application display to the proper mode to access the desired menu (see The TSX-1620 Application Displays for details).

To change the port display form:

1.Click in the appropriate area to display the Interface or Bridge menu (refer to Figure 2-3on page 2-5).

2.Drag down to Port Display Form, then right as necessary to select one of the port display options. The current selection will be displayed in the Port Display Form text box, just above the ports.

Interface Port Display Form Options

Oper Status

The Oper Status port display form displays the current status of the port — ON, OFF, NLK (no link), Test, or ---(unknown). Oper Status is determined by a combination of MIB-II interface operational status (ifOperStatus), administrative status (ifAdminStatus), and the interface’s physical link status (if applicable).

•The ON status indicates that the interface’s operational status is determined as “UP”, that it has been administratively enabled, and that a physical link has been detected at the port. A status of ON indicates that the port can send and receive NMS packets, but does not indicate whether the port’s bridging functions are enabled.

NOTE

To determine whether a port’s bridging functions are enabled, change the application display mode to Bridge, and then select the Admin port display form. For more information, see the definition of the Admin port display form, below.

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.
