6.Click on to save the changes you have made and exit the Special Database Filter window.

Changing the Receive Ports

You can set the receive ports in the Special Filter Database window either before or after you deÞne a Þlter. These are the ports at which the frame must be received for the Þltering parameters to apply. The default selection is Port 1.

To designate a receive port, click on the receive port icon () for the Þlter. As you click on the icon, it will cycle though the ports (e.g., 1, 2, 3, 4, etc. until the end of the interface table, and Ò*Ó). When you have selected a port, you can set the port Þltering action that will apply when the packet is received at that particular port (refer to the following section for further information).

In this fashion, you can specify all receive ports at which the packet must be received and the designated Þltering action which will apply when the packet is received at each port. Selecting Ò*Ó (promiscuous or any port) will apply the Þlter and its speciÞed Þltering action to all ports on the device.

Remember that you can only view a single receive port and its Þltering action. To check all receive ports for a single Þlter, you must click on the receive port icon to cycle through the series of ports.

Changing the Port Filtering Action

Use the port icons under the Port Filtering section of the Special Filter Database window to determine the port Þltering action associated with the Þlter when it is received at a speciÞed receive port. You can select the port Þltering action either before or after deÞning the Þlter. By default, the Þltering action is initially not set at any port. You must click on a port to invoke the Þltering action symbols. After the Þrst port is set (either to Þltering or blocking), the remaining ports in the Þlter are set to blocking until you specify otherwise.

Setting the Port Filtering Action

When you set the port Þltering action for a Þlter, you determine whether the port will block or forward packets which match the ÞlterÕs speciÞcations. To set port Þltering action, click on the desired port icon (e.g., 1, 2, 3, 4, 5, 6, up to 32) to toggle from blocking ( ) to forwarding () or vice versa.

You can set the port Þltering action for the bridging port on each port of the device, as well any BRIM ports.

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.
