CSX400 Configuration with QuickSET

This section describes the fields in the first Bridging and Routing configuration window.

Inverse Mux (Multiplex) Configuration — This function lets you balance your LAN traffic between two T1 WAN ports, and is used with Point to Point Protocol (PPP) or HDLC protocol. QuickSET automatically sets the WAN Frame Type to Encapsulated Ethernet when you use the Inverse Mux configuration. When you select the Inverse Mux check box, bridging, IP routing, and IPX routing functions are all disabled. The WAN device at the other end of the WAN link(s) must be a Cabletron Systems device, capable of receiving the balanced WAN traffic.

NOTE

The Inverse Mux function is enabled or disabled through QuickSET, not Local Management. Statistics regarding the Inverse Mux configuration are accessed via the imux MIB Navigator command. See Chapter 9, MIB Navigator, for more information.

MAC Bridging — This field allows you to specify whether the CSX400 bridges traffic. Click on the check box to turn MAC Bridging on.

Spanning Tree Protocol — This field is grayed out until MAC Bridging is turned on. It allows you to configure the CSX400 to use the Spanning Tree Protocol, which lets the remote device check for bridging loops, and other sites that use the Spanning Tree Protocol. Click on the check box to turn on Spanning Tree Protocol.

IP Routing — The IP Routing check box allows you to turn on/off IP Routing. Click on the check box to turn on IP Routing.

IPX Routing — The IPX Routing check box allows you to turn on/off IPX Routing. Click on the check box to turn IPX Routing on.

External Ethernet 1 Network # — This field displays the IPX network number assigned to the external Ethernet network on Ethernet port 1. It is grayed out until IPX Routing is turned on.

External Ethernet 2 Network # — This field displays the IPX network number assigned to the external Ethernet network on Ethernet port 2. It is grayed out until IPX Routing is turned on.

Frame Type — This field is grayed out until IPX Routing is turned on. It allows you to select the type of IPX frame in which packets are encapsulated for transmission. Select one of the four available frame types.

CSX400-DC, 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.
