Bridging

¥Blocking (orange)ÑThe port is on-line, but Þltering trafÞc from going across the bridge from one network segment to another. Bridge topology information will be forwarded by the port.

Interface Type

Indicates the interface type which applies to each device bridging port interface (e.g., ethernet). The interface type (ifType) is a mandatory object type from the SNMP MIB II Interface (if) Group.

Bridge Address

Indicates the physical address of the bridge interface.

Speed

Indicates the speed of the interface in Mb/s or Gb/s.

Accessing Other Options from the Bridge Status Window

At the top of the Bridge Status window, you can click to access a menu that provides other bridge management options. Depending on which device you are monitoring via SPECTRUM Element Manager, the following bridge management options will be available:

¥The Module TypeÉ window displays a description of the device that is currently being monitored.

¥The Find Source AddressÉ window allows you to discover the bridge interface through which a particular MAC address is communicating (see Using the Find Source Address Feature, page 4-63).

¥The Performance GraphÉ window displays statistics for trafÞc across the entire bridge (see Performance Graphs, page 4-15).

¥The Spanning TreeÉ window allows you to set the Spanning Tree Algorithm parameters for bridging on your device (see Bridge Spanning Tree,

page 4-35).

¥The SmartTrunkÉ option invokes the SmartTrunk ConÞguration and Status window, which enables you to group interfaces logically to achieve greater bandwidth between devices, if both devices support the SmartTrunk feature. There is no limit to the number of ports that can be included in a single Òtrunk,Ó nor is there a limit to the number of trunked ÒinstancesÓ that can be supported (see ConÞguring SmartTrunking, page 4-96).

¥The Filtering DatabaseÉ window lets you see the contents of the Static and Learned databasesÑthe two address databases which construct the IEEE 802.1 Source Address Table. The bridge uses the contents of these databases to make its packet Þltering and forwarding decisions. You can conÞgure the bridgeÕs acquired and permanent Þltering databases to Þlter or forward trafÞc across the device (see Filtering Database, page 4-42).

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.
