Bridging

Collision Errors

Single

Displays the number of successfully transmitted frames on the selected interface for which transmission was prevented by one collision.

Multiple

Displays the number of successfully transmitted frames on the selected interface for which transmission was prevented by more than one collision.

Late

Displays the number of times that a collision has been detected on this interface later than 51.2 microseconds into the transmission of the packet on a 10 Mbit/s system or later than 5.12 microseconds on a 100 Mbit/s system.

Excessive

Displays the number of frames from this interface for which transmission was not complete due to excessive collisions.

Collision Errors

Displays the total number of collision errors of all types that occurred during transmission from this interface.

The PPP Link Statistics Window

The PPP Link Status menu option opens the PPP Link Statistics window, which enables you to view color-coded statistics related to the PPP (Point-to-Point Protocol) link at the selected interface.

The Point-to-Point Protocol is a standard method of transporting multiprotocol datagrams over point-to-point links. A PPP Link provides full-duplex communication between the endpoints, allowing a simultaneous bidirectional operation that should maintain the order in which data packets are transmitted.

To access the PPP Link Statistics window

from the Bridge Status window:

1.Click on the desired Port button () to display the port menu.

2.Drag down to select PPP Link Status…. The device port PPP Link Statistics window, Figure 4-7, will appear.

from the Chassis View window:

1.Click on the appropriate port index to access the Port menu.

CSX200, CSX400 specifications

Cabletron Systems was a leading developer of networking solutions, and its CSX400 and CSX200 series of high-performance switches represent some of the key innovations in the field of enterprise networking during their time. Both models were geared towards enhancing network reliability, efficiency, and speed, particularly in environments where heavy data traffic and complex networking demands were prevalent.

The CSX400, designed for larger enterprises, boasts a robust architecture capable of handling significant throughput. One of its standout features is its stackable design, allowing multiple switches to be interconnected and managed seamlessly as a single unit. This scalability provides organizations with the flexibility to expand their networks without significant infrastructure overhauls. The CSX400 supports various Ethernet standards, including 10/100 Ethernet and Gigabit Ethernet, positioning it to effectively manage both legacy and modern networking requirements.

In addition to its scalability, the CSX400 is distinguished by its advanced Layer 2 and Layer 3 routing capabilities. This dual-layer functionality enables efficient data handling and is instrumental in managing traffic between different network segments. Moreover, the switch incorporates features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS) prioritization, allowing for enhanced performance of critical applications and streamlined bandwidth allocation.

On the other hand, the CSX200 series is tailored for smaller enterprises or branch offices needing a reliable yet efficient networking solution. Despite its compact design, the CSX200 is equipped with essential features that promote effective network management and security. It offers a simplified management interface, making it user-friendly for network administrators. The switch also provides essential access control measures, employing technologies like IEEE 802.1X for network access security.

Both the CSX400 and CSX200 prioritize performance through the incorporation of advanced switching technologies. They support features such as Spanning Tree Protocol (STP), enabling loop-free topologies and enhanced network resilience. These attributes are particularly crucial in dynamic networking environments where downtime can have significant repercussions on business operations.

Overall, Cabletron Systems' CSX400 and CSX200 series represent a blend of scalability, advanced routing capabilities, and user-friendly management, making them vital assets for organizations looking to optimize their network infrastructure during a period of rapid technological evolution. With their rich feature sets and unwavering performance, these switches helped pave the way for modern networking solutions that cater to diverse enterprise needs.
