Bridge Performance Graph Window Fields

You can select the following statistics to display in the Bridge Performance Graph or Bridge Port Performance Graph. Statistics are provided numerically (as an average or peak value) and graphically. The device is polled for the graphed information every 2 seconds, and numeric values are updated based on this poll.

The graph updates at the Þxed two second interval. For the Þrst 60 seconds of graphing, you will note the graph lines extending as each intervalÕs data is added to the graph. Once the Þrst 60 seconds has passed, the newest data is added at the right edge of the graph, and the oldest data is scrolled off to the left.

Peak statistics are based on the peak level of activity returned from a single poll since the Performance Graph window was invoked. A date and time is provided for peak levels.

The Average statistics are updated every two seconds as averaged over the previous four poll intervals (i.e., averaged over a sliding eight second time window).

Frames Forwarded (Green)

ForwardedThe number of frames forwarded by the deviceÕs bridge, at the device or port level.

Nothing

The Frames Forwarded function is currently not

Filtered (Magenta)

 

Filtered

The total number of frames Þltered by the deviceÕs

 

bridge, at the device or port level.

Nothing

The Filtered scale is not currently measuring the number

 

of packets Þltered by the bridge at the device or port

 

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.
