Using the TSX-1620 Hub View

Yellow

No Link — The interface’s operational status is returned as “UP”

 

and it has been administratively enabled, but no physical link

 

state to the port has been detected. This will not appear for

 

interfaces that do not support link state.

Blue

Off — The interface is physically disabled (its operational status

 

is returned as “DOWN”), and it had also been administratively

 

disabled prior to entering the physically disabled state.

Red

Off — The interface is physically disabled (its operational status

 

is returned as “DOWN”); however, prior to being physically

 

disabled, the port had been in an administratively enabled state.

(Magenta

UNKnown — The interface cannot return the requested

 

information.

Gray (---)

Unknown — The port’s ifOperStatus was not returned from the

 

device; the state of the port cannot been determined.

Bridge Port Display Form Options

Admin

Display’s the port’s current bridging status — FWD (forwarding), DIS (disabled), LIS (listening), LRN (learning), BLK (blocking), BRK (broken), or UNK (unknown). These bridge port status conditions are defined as follows:

•FWD (forwarding) when the interface is on-line and forwarding packets from one network segment to another.

•DIS (disabled) when bridging at the interface has been disabled by management, and no traffic can be received or forwarded on this interface.

•LIS (listening) when the interface is not adding information to the filtering database. It is monitoring Bridge Protocol Data Unit (BPDU) traffic while preparing to move to the forwarding state.

•LRN (learning) when the Forwarding database is being created, or the Spanning Tree Algorithm is being executed because of a network topology change.

•BLK (blocking) when the interface is on-line, but filtering traffic from going across the TSX-1620 from one network segment to another.

•BRK (broken) when the physical interface has malfunctioned.

•UNK (unknown) if the interface’s status cannot be determined.

Tp Frames Forwarded

Displays the percentage of Transparent bridging frames that have been transmitted to or received from the port’s attached segment that have been forwarded to their destination.

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.
