Bridging

Making and Setting Changes

The Source Route ConÞguration window allows you to affect changes for the following Source Route Bridging parameters: Bridge Number, Local Segment, Target Segment, Hop Count Limit, and the deviceÕs Spanning Tree Mode.

To make a change to Bridge Number, Local Segment, Target Segment, or Hop Count Limit, use the mouse to highlight the existing value in the desired Þeld, and type in a new value.

To set the Spanning Tree Mode to Auto or Manual, click on the radio button next to the appropriate selection. If set to Auto, a Spanning Tree Algorithm will calculate the deviceÕs priority in a series of parallel bridges to determine a root bridge on the network. If set to Manual, you conÞgure a Spanning Tree by administratively enabling or disabling each bridging port on the network.

When the deviceÕs Spanning Tree Mode is set to Manual, you can change how a bridge port will treat a Spanning Tree Explorer frame. Use the Enable checkbox to allow STE frame forwarding at the port, or use the Disabled checkbox to prevent STE frame forwarding at the port. Click on the Enabled or Disabled checkbox to make your selection.

When you make changes in the Source Route ConÞguration window, they are not implemented at the device until you click on the Set button. This will cause the device to reboot. Since rebooting the device will bring it down for several minutes, a ÒReset with new parameters?Ó pop-up dialog box will appear to ensure that you are ready. Click on OK to accept the changes, or Cancel to return to the Source Route ConÞguration window.

Using the Find Source Address Feature

You can select the Find Source Address option to discover which bridging interface a speciÞed source MAC address is communicating through. When you select the Find Source Address option, a search is made of the 802.1d Bridge Filtering Database to discover the bridge interface associated with the address that you specify. If the search is successful, the corresponding interface will ßash in the Chassis View window. For more information on the Filtering Database, refer to Filtering Database on page 4-42.

Use the Find Source Address feature as follows:

1.Click to display the Device menu.

2.Drag to Find Source Address…. The following window will appear.

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.
