CSX400 Configuration with QuickSET

Source IP — The Source IP field displays the IP address of the source device accorded the permissions set in the permissions field. To set permissions for a source device, place the cursor in the Source IP field and type the IP address of the source that you wish to set permissions.

Source Mask — Displays the mask for the Source IP address specified in the Source IP field. To set the mask for the specified source IP address, place the cursor in the Source Mask field and type the mask.

The default Mask for both the source and destination addresses is 0.0.0.0, which masks the entire address, causing all addresses to match the filter. In other words, the default access control list allows all traffic to pass. Entering a mask of 255.255.255.255 causes only packets matching the exact address you have entered to match the filter.

For a Class C address, entering a mask of 255.255.255.0 causes packets with the same class C subnet as the IP address to match, thereby causing the access control filter to apply to all hosts on this particular subnet.

Dest IP — The Dest IP field displays the IP address of the destination device accorded the permissions set in the permissions field. To set permissions for a certain destination device, place the cursor in the Dest IP field and type the IP address of the destination for which you wish to set permissions.

Dest Mask — Displays the mask for the Destination IP address specified in the Dest IP field. To set the mask for the specified destination IP address, place the cursor in the Dest Mask field and type the mask.

Protocol — Use this pull-down list to select the upper layer protocol that you want to apply to the access control filter. Each access control filter can apply to traffic for all protocols included in the TCP/IP suite, or just to traffic for a single protocol.

Permission — Use this pull-down list to set the permissions for the specified control filter. Options for this field include permit, deny, permit bi-directional, or deny bi-directional. Choosing permit allows the specified packets to be forwarded, while choosing deny blocks the specified packets. Choosing permit bi-directional or deny bi-directional either permits or denies traffic to and from a specified source or destination.

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.
