Bridging

At the device level, a Detail button on the window allows you to compare the packets forwarded, Þltered, or transmitted on all networks supported by the device, as well as errors on all networks.

For a selected bridged network, the Detail button allows you to view the number of packets forwarded to, or received from, each other network supported by the device.

To access the device-level Bridge Performance Graph window

from the Bridge Status window:

1.Click on to display the Bridge menu.

2.Drag down to select Performance Graph…. The device Bridge Performance Graph window, Figure 4-2, will appear. (The individual port Bridge Performance Graph windows are similar, except that they display a graph applicable to the selected interface.)

from the Chassis View window:

1.Click on the Board Index of the device of interest; the Board menu will appear.

2.Drag down to select Performance Graph…. The device Bridge Performance Graph window, Figure 4-2, will appear.

To access the port-level Bridge Performance Graph window

from the Bridge Status window:

1.Click on the desired Port button () to display the port menu.

2.Drag down to select Performance Graph…. The port Bridge Performance Graph window, Figure 4-2, will appear.

from the Chassis View window:

1.Click on the appropriate port index to access the Port menu.

2.Drag down to select Performance Graph…. The port Bridge Performance Graph window, Figure 4-2, will appear.

NOTE

The displayed graphic in Figure 2-2 is a device-level window; the window that is displayed at the port level is virtually identical to the one at the device level.

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.
