Bridging

Mode

Displays the connection type for each port, either User or Network. User connections do not participate in SmartTrunking; Network connections do. At least two ports (from two separate chassis) must be designated as Network connections to participate in SmartTrunking. All FNB interfaces must be designated as User connections.

SmartTrunk State

Displays the current operating state of each listed port. The possible states include:

¥NoneÑThe port is operating as a normal switch port.

¥BlockingÑThe port is load sharing, but in the blocked mode. While the module performs the function of determining if there is a network loop, data is temporarily blocked on new SmartTrunk ports and on any port that becomes newly linked.

¥SmartTrunkingÑThe port is load sharing with other Network-designated ports of the same instance.

Instance

Displays the ports associated with each redundant loop. A module can have multiple instances.

# SmartTrunks

Displays the total number of load-sharing ports in the redundant loop.

The only conÞgurable Þelds in the SmartTrunk ConÞguration and Status window are the two Þelds with radio buttons, each with two possible settings: SmartTrunk (with the options of Enable and Disable) and Enable and Disable Port # X (with the options of LoadSharing and Disable).

NOTE

When you Þrst open the SmartTrunk ConÞguration and Status Screen, the Enable and Disable Port # X Þeld will be labeled SmartTrunk State Port #. After you click on a port number in the list box, the Þeld title will change to Enable and Disable Port # X.

To enable or disable SmartTrunking on an individual interface:

1.Click to select the interface number under the Port column in the list box for which you wish to enable or disable SmartTrunking.

2.Click on the empty radio button adjacent to one of the two choices in the

SmartTrunk field:Enable or Disable. When the radio button is filled ( ), the selected choice will be enabled.

3.Click on Set to apply your selection, or Cancel to exit the window without applying the change.

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.
