Bridging

¥The SmartTrunk 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 Token Ring Bridge Mode window lets you select which type of bridging that will be used by the Token Ring bridging deviceÑTransparent, Source Routing, or Source Route Transparent (see Token Ring Bridge Mode, page 4-83).

¥The Bridge ConÞguration option opens a window that allows you to set address and routing information for all interfaces on a Token Ring bridging device, including the Bridge Number and the Virtual Ring Number. It also allows you to set source route bridging parameters at the device level (see Using the Bridge and Port ConÞguration Windows, page 4-92).

¥The Port ConÞguration option opens a window that allows you to view the address and routing information for an individual Token Ring bridging interface. This window displays information that is set at the device level via the Bridge ConÞguration window, such as the Bridge Number and the Virtual Ring Number. It also allows you to set source route bridging parameters for that port (see Using the Bridge and Port ConÞguration Windows, page 4-92).

¥The I/F ConÞguration port-level menu option invokes the Interface ConÞguration window, which allows you to select a bridging method for a Token Ring bridging interface. This window also allows you to select one of three transmission methods that should be used when unknown addresses are received from end stations attached to the selected bridge port (see Using the Interface ConÞguration Window, page 4-89).

¥The Source Route ConÞguration option enables you to conÞgure source routed trafÞc passing between bridge ports (see Source Route ConÞguration, page 4-57).

NOTE

The menu options that are available will vary depending on the type of device you are monitoring, and on the type of bridge interfaces supported by the device.

The following sections detail how to use each of the bridge management windows.

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.
