Bridging

When a sending station needs to determine the best route to an intended destination, it transmits an All Paths Explorer (APE) frame. The APE frame contains no routing information; it is propagated along all available paths to the destination station, which then directs a reply back to the source. The Þrst reply received by the original sending station is considered the most efÞcient route and is used in subsequent transmissions.

Span. Tree Expl.

Displays the total number of Spanning Tree Explorer (STE) frames received by the indicated port from its attached segment.

STE frames, also known as Single Route Broadcast frames, follow the topology established by the Spanning Tree Algorithm.

Transmitted Frames

Specif. Routed

Displays the total number of SpeciÞcally Routed Frames transmitted by the indicated port onto its attached segment.

All Paths Expl.

Displays the total number of All Path Explorer frames transmitted by the indicated port onto its attached segment.

Span Tree Expl.

Displays the total number of Spanning Tree Explorer (STE) frames transmitted by the indicated port onto its attached segment.

Discards

Segment Mismatch

Displays the number of explorer frames discarded because their routing descriptor Þeld contained an invalid value for a segment attached to the port.

The routing information Þeld of a SpeciÞcally Routed frame contains LAN Segment In (Ring In)ÐBridge NumberÐLAN Segment Out (Ring Out) information. If the bridgeÕs LAN Segment Out value does not match the LAN Segment Out speciÞed in the frameÕs Routing Information Field, the bridge logs a Segment Mismatch and discards the frame.

Duplicate Segment

Displays the number of frames discarded because the frameÕs Routing

Information Field identiÞes a particular segment more than once.

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.
