Bridging

You set an interface to use standard or full duplex by selecting the appropriate mode from this window. When you open the Port ConÞguration window the currently used mode appears selected.

To change the mode from standard to full duplex mode or from full duplex to standard mode, click in the radio button of the appropriate option and then click on Apply. To cancel the action without applying any changes, click on Cancel.

Fast Ethernet Port Configuration

You can use the port-level Fast Ethernet ConÞguration window to manually conÞgure 100Base-TX Fast Ethernet ports and FE100-TX Fast Ethernet Interface Modules (FEPIMs) for 10Base-T and 100Base-TX full or half duplex operation. You can also conÞgure them to auto-negotiate with the device at the other end of the connection, based upon each deviceÕs Advertised and Remote Capabilities.

If you are monitoring a device with 100Base-FX Fast Ethernet ports, you can use the Fast Ethernet ConÞguration window to manually conÞgure them to full or half duplex operation. No auto-negotiation is available for the 100Base-FX ports, and by extension, no Advertised or Remote capabilities.

From this window you can manually set the operational mode of the port, determining the speed of the port (10 Mbps or 100 Mbps), and whether it uses full duplex or standard mode bridging.

You can also set a 100Base-TX port to auto-negotiation so that the appropriate operational mode can be determined automatically (using the Advertised Abilities of the local interface that you determine, and the Remote Capabilities of the Remote Link). The mode you set will determine the speed of the port and whether it uses full duplex or standard mode bridging.

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.
