CSX200 and CSX400

WAN Configuration

Physical CSX device information; CSX WPIMs; the WAN Logical View window

The CSX200 devices have one WAN interface, a Cabletron Wide Area Port Interface Module (WPIM) installed at the factory. The CSX400 has two swappable WAN interfaces, which can currently consist of any combination of CabletronÕs T1/E1/DI, HDSL, DDS, or synchronous WPIMs.

NOTE

ItÕs important to note that a Windows 95- and NT-based utility called QuickSET was shipped with your CyberSWITCH. This program is designed for point-and-click installation and set-up of CSX200/400 devices. Currently, QuickSET should be used to conÞgure all WPIM settings and routing/bridging protocols, including those WPIMs not currently supported by Spectrum Element Manager. See your QuickSET documentation for more information. Future releases of SPECTRUM Element Manager will support the CSX200/400 more comprehensively.

The CSX200 series (201, 202, and 203) and the CSX 400 come with a variety of Ethernet LAN and WAN connectivity options. The WPIMs which provide the WAN connection(s) are discussed in this chapter, along with EPIM possibilities for the CSX400.

WAN Logical View on page 3-5discusses how to access the WAN Logical View window through SPECTRUM Element ManagerÕs Chassis View. There, you can view your WAN interface settings.

About the CSX200 Series

There are three devices in the CSX200 family: the CSX201, CSX202, and CSX203. Each has twelve RJ-45 Ethernet ports for LAN connection via 10BaseT twisted

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.
