Priority Configuration

The SmartSwitch 2000 devices support priority packet forwarding. Priority packet forwarding lets you designate certain packets to be of higher importance than others, thereby allowing for the forwarding of these packets before packets of lower priority. This functionality is essential for time-critical applications Ñ such as real-time video Ñ on shared networks.

NOTE

The Priority ConÞguration menu option will only appear in the Device menu for devices that respond to any of SPECTRUM Element ManagerÕs queries to the following OIDs: ctPriorityExtPortStatus, ctPriorityExtMaxNumMACEntries, or ctPriorityExtNumPktTypeEntries. If your deviceÕs Þrmware does not respond to these queries, contact the Cabletron Systems Global Call Center for Þrmware upgrade information.

Frame priority is enabled by the ÒtaggingÓ of MAC frames so that they are given a priority designation when they are forwarded by the SmartSwitch 2000 device Ñ which is a tag-aware switch (i.e., one that adheres to the IEEE P802.1p and IEEE P802.1q Draft Standards). Tagging a frame is accomplished by adding a Tag Header to a frame immediately following its original Destination and Source MAC address Þelds (and any routing Þelds, if present), and then recomputing the Frame Check Sequence (FCS) appropriately. On receiving such a frame, a tag-aware switch will read the priority from the tagged portion of the frame, remove the Tag Header, recompute the FCS, and then direct it to its appropriate transmission queue.

There are eight priority levels Ñ indicated 0 through 7Ñ available to designate user priority. Frames tagged with a 0 represent the lowest priority level (or normal) trafÞc, and frames tagged with a 7 indicate the highest priority level trafÞc.

The SmartSwitch 2000 itself supports two transmission queues: one that is for 0 or normal priority trafÞc (or any non-tagged trafÞc), and a second queue that is reserved for frames that have been tagged with a priority level of 1 or higher. On receiving any priority-tagged frames, the SmartSwitch 2000 will forward them out of the high priority queue before forwarding any frames in the normal

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.
