Bridging

FNB State

The FNB State section displays, and lets you conÞgure, the state of the backplane FNB connectors on the ETWMIM.

The right-hand side of the window displays the current connection conÞguration for the FNB connectors on the ETWMIM, and lets you alter those options by using the appropriate radio button selections:

¥Connect Left indicates that the ETWMIM is/will be connected on the FNB to the Þrst board to its left in the MMAC chassis with a valid right FNB connection.

¥Disconnect Left indicates that the ETWMIM is/will be disconnected on the FNB from any boards to its left in the MMAC chassis.

¥Connect Right indicates that the ETWMIM is/will be connected on the FNB to the Þrst board to its right in the MMAC chassis with a valid left FNB connection.

¥Disconnect Right indicates that the ETWMIM is/will be disconnected on the FNB from any boards to its right in the MMAC chassis.

¥Enable Bypass indicates that the ETWMIM is/will be in bypass state. It will not be connected to any boards on its left or right. In a shunting chassis, the FNB will bypass the board to maintain the integrity of the ring across the chassis.

¥Disable Bypass indicates that the ETWMIM is/will be inserted into the FNB, according to the established FNB connection options above.

The left-hand side of the window indicates the results of the current FNB conÞguration, with an X next to the appropriate state of the FNB connection: Connected Left, Connected Right, Bypassed, Right Connection Fault, or Left Connection Fault. For example, if you choose Connect Right and Disconnect Left, the Connected Right and Left Connect Fault Þelds will appear with an X next to them.

Active Monitor

This Þeld allows you to conÞgure whether or not the ETWMIMÕs onboard management station will engage in the active monitor contention process, which occurs as part of the recovery procedures initiated after certain ring error situations.

If you select Enable, the station will contend in the process used to establish a ring station as an Active Monitor.

If you select Disable, the station will not contend, even if the contention process is activated for the ring. Note that if the ETWMIM is currently serving as the active monitor, it will continue in that role until the next contention.

The box to the left of the choices will reßect your actions by displaying On when the Active Monitor has been enabled, and Off when the Active Monitor has been disabled.

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.
