priority queue. However, the SmartSwitch 2000 will tag outgoing frames with the full range of eight priority levels, so that upon reception, a device that supports the entire range of priority queuing will forward the frame appropriately.

You can use SPECTRUM Element Manager to conÞgure the criteria that determine the priority in which frames will be queued for transmission by your SmartSwitch 2000. Several different criteria can be used to determine a frameÕs transmission queue order:

¥The device and port at which the frame was received.

¥The destination and/or source MAC address associated with the frame.

¥A combination of destination and/or source MAC address and the frameÕs protocol type.

¥The frameÕs protocol type.

When you conÞgure the transmission queue for a speciÞc frame, an entry is made in one of three priority tables maintained by the SmartSwitch 2000 device. These tables are used to determine which transmit queue to use Ñ normal priority or high priority Ñ when forwarding frames.

¥The ctPriorityExtPortTable maintains priority entries based on a frameÕs receive port.

¥The ctPriorityExtMACTable maintains priority entries based on a frameÕs MAC-layer information.

¥The ctPriorityExtPktTypeTable maintains priority entries based on the frameÕs protocol type.

The following sections discuss how to use the Port Priority ConÞguration window, the MAC Based Priority ConÞguration window, and the Frame Priority ConÞguration window to make entries in these transmit priority tables.

Configuring Priority Queuing Based on Receive Port

You can use the Port Priority ConÞguration window, Figure 2-20, to determine packet queuing based solely upon the port at which the packet was received. This allows you to ensure that a connected user or LAN segment will have priority when frames that were received on that port are queued for transmission.

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.
