The following operational modes can be speciÞed:

Speed

This Þeld speciÞes a port speed of 10MB, 100MB, or 1000MB.

Duplex

This Þeld speciÞes Half Duplex or Full Duplex mode for the port.

Flow Control

Flow control allows Ethernet devices to notify attached devices that congestion is occurring and that the sending device should stop transmitting until the congestion can be cleared. There are two commonly used methods of ßow control: Frame-based (operates on Full Duplex links) and Backpressure (operates on Half Duplex links).

Ports set to Full Duplex mode have frame-based ßow control, using pause control frames. Frame-based ßow control options are:

Symmetric The port is able to both receive and transmit pause control frames.

Asymmetric RX This option appears only for Gigabit Ethernet ports. The port will receive pause control frames, but will not transmit its own.

Asymmetric TX This option appears only for Gigabit Ethernet ports. The port is

 

capable of sending pause control frames, but will not

 

acknowledge received pause control frames.

Disabled

Disables ßow control on the port.

Auto Negotiate

Ports conÞgured to operate in auto negotiation mode will only

 

use pause control frames if the negotiation process determines

 

that the link partner supports them. Both ends of the link must

 

support auto negotiation and a common mode of operation.

Ports set to Half Duplex mode use Backpressure ßow control. Backpressure ßow control simply asserts the carrier sense signal out the port causing the device transmitting to detect a collision, stop transmitting data, and send the jam signal. Backpressure ßow control options are enabled or disabled.

Setting the Desired Operational Mode

For any 100Base-TX port, you can conÞgure operational modes, or you can select Auto Negotiate mode, which allows the port to negotiate with its link partner to Þnd the highest mutually available bandwidth and ßow control. If you select Auto Negotiate mode, you must also choose which of the portÕs bandwidth and ßow control capabilities you wish to advertise to the link partner (refer to Auto Negotiation Technologies, page 2-42).

2000 specifications

Cabletron Systems was a prominent company in the networking and communications industry during the late 20th century, and by the year 2000, it had established itself as a leader in providing high-performance networking solutions. The company was known for its innovative approach to network architecture and its commitment to delivering reliable products that enabled seamless connectivity in various environments.

One of the primary features of Cabletron Systems in 2000 was its advanced networking technologies, including Local Area Network (LAN) and Wide Area Network (WAN) solutions. The company specialized in developing multi-layer switches that could efficiently manage traffic and deliver high-speed data transfer. Their products were particularly popular in enterprise settings, where network performance and reliability were paramount.

Cabletron's solutions included a range of products, from Ethernet switches to routers, which were designed with scalability and flexibility in mind. This allowed businesses to adapt their networks to accommodate growth, without the need for a complete overhaul of their infrastructure. The company’s Integrated Networking Architecture (INA) was a significant innovation during this period, enabling efficient communication and management of diverse network resources.

Another major characteristic of Cabletron Systems was its commitment to interoperability. The company’s products were designed to be compatible with several industry standards, ensuring that organizations could easily integrate Cabletron solutions into their existing networks. This focus on compatibility helped to foster collaboration among different devices and systems, further enhancing network efficiency.

Security was also a key feature of Cabletron’s offerings in 2000. With growing concerns about data breaches and unauthorized access, the company incorporated advanced security measures into its products. These features included robust authentication protocols, encryption options, and secure management interfaces, which helped safeguard sensitive data during transmission.

Customer support and service were paramount to Cabletron Systems' business model. The company provided extensive resources, including training and technical support, to ensure that customers could maximize the potential of their networking solutions. This dedication to customer satisfaction contributed significantly to Cabletron’s reputation in the marketplace.

In summary, Cabletron Systems in 2000 emerged as a frontrunner in the networking industry, characterized by its innovative technologies, commitment to interoperability, emphasis on security, and strong customer support. Their products and solutions were designed to empower businesses, helping them achieve greater efficiency, scalability, and reliability in their network operations.
