Bridging

Desired Operational Mode

Displays the operational mode that you want to conÞgure for this port. The following operational modes are available for each port:

FE-100TXAuto-Negotiation, 10Base-T, 10Base-T Full Duplex, 100Base-TX, and 100Base-TX Full Duplex.

FE-100FX100Base-FX and 100Base-FX Full Duplex

See Setting the Desired Operational Mode for the FE-100TXand Setting the Desired Operational Mode for the FE-100FX, following, for more information.

Advertised Abilities

This Þeld works in conjunction with auto-negotiation on FE-100TX ports. During auto-negotiation, the local hardware will advertise all selected modes in descending bandwidth order: 100Base-TX Full Duplex, 100Base-TX, 10Base-T Full Duplex, and 10Base-T.

Of the selected abilities, the highest mode available on the port on the other side of the connection will automatically be used. The Advertised Abilities will only be used when auto-negotiation is enabled.

Remote Capabilities

This Þeld displays the advertised abilities of the remote hardware at the other end of the link from the FE-100TX port. Again, possible advertised abilities by the remote partner include 10Base-T, 10Base-T Full Duplex, 100Base-TX, or 100Base-TX Full Duplex.

If auto-negotiation is not enabled or supported at either the local or remote interface, or if there is no active link, all entries in this Þeld will be grayed out.

NOTE

Auto-negotiation is not available on the FE-100FX; therefore, the Advertised Abilities and Remote Capabilities section of the Fast Ethernet ConÞguration window will be grayed out when you are viewing the port conÞguration of an FE-100FX.

!

CAUTION

If you choose to select a speciÞc mode of operation (rather than auto-negotiation), you should be sure that the link partner supports the same mode. Otherwise, no link will be achieved.

If you select a full duplex mode and the link partner supports the same wire speed but not full duplex, a link will be achieved, but it will be unstable and will behave erratically.

If you select auto-negotiation, the local node will try to match the mode of the link partner, even if the link partner is not set to auto-negotiate, and even if the local node must use a mode which it is not currently advertising.

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.
