Bridging

Changing the Receive Port

You can change the Receive port of an address entry in the scrollable panel, so that a frame must be received at the speciÞed port for the Þltering action to apply. To do so, click on the Receive port in the panel. With each click, the Receive port will cycle to the next port (e.g., from * (promiscuous), to 1, to 2, to 3, to 4, to 5, up to 32, back to *).

Changing the Port Filtering Action

You can change the Port Filtering action at each bridge port from its current action to the opposing action.

1.Maneuver the scroll bar until the desired port is in the Port Filtering panel.

2.Click on the port to alter its filtering action from forwarding frames from the

associated address (

), to filtering frames (

) (or vice versa).

Adding or Deleting Individual Entries

You can add or delete entries individually from the Filtering Database.

To add an address:

1.Click on the New button in the lower left of the window. A window (Figure 4-12) will appear.

2.In the Filter Address field, type in the address (Hex format) for which you desire bridging. Be sure to add “-” as a separator between each byte in the address.

3.In the Receive Port field, type in the port at which the address must be detected for bridging to take place. If you enter a value of 0 in this field, the Receive Port is considered promiscuous (i.e., any port), and will be

designated by an “ in the Address Entry panel. *

4.Click on .

5.Specify the Port Filtering action on the address entry as described in the previous section.

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.
