General Configuration Using Local Management

Subnet Mask — This field displays the default Subnet Mask, and allows you to enter a new value for the Subnet Mask if necessary. Subnets are logical divisions of the network that isolate groups of devices. The Subnet Mask determines how the CSX400 directs SNMP traps to a management workstation. If the CSX400 resides on the same network as the management workstation, then the CSX400 sends SNMP traps directly to the management workstation. If the CSX400 resides on a different subnet as the management workstation, then the CSX400 sends SNMP traps to a gateway or router.

•When the management workstations designated to receive SNMP traps reside on the same network as the CSX400, use the Subnet Mask default setting for the IP address entered on the System Level screen.

•Set a new value for the Subnet Mask when the management workstations designated to receive SNMP traps reside on a different subnet (for example, across a gateway or router)

To set a Subnet Mask, refer to the Setting the Subnet Mask section.

Phys Address — This field displays the physical address of the CSX400. You cannot modify the physical address.

Default Gateway — Use this field to enter the Default Gateway for the CSX400. When routing packets, the CSX400 uses the IP Forwarding Table to find the route to each destination address. The IP Forwarding Table contains the routes to all networks and hosts within a certain area.

However, the IP Forwarding Table on its own cannot provide all of the routes that may be needed. The CSX400 relies on a Default Gateway to provide the routes to destinations that are not listed in its own IP Forwarding Table. The Default Gateway is the IP address of the network device (gateway or router) used to forward SNMP traps to a management station. The default setting for this field is NONE DEFINED. To set the Default Gateway, refer to Setting the Default Gateway.

Default Interface — Use this field to select the default interface for the CSX400 Default Gateway. The default interface is the channel which is set up to handle SNMP traps sent to an IP station that is not on the same subnet as the CSX400 in an IP routed environment. The default setting for this field is NONE DEFINED. To set the default interface for the Default Gateway of the CSX400, refer to Setting the Default Interface.

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.
