The Catalyst 2950-24-LRE Series Intelligent Ethernet Switches provides customers the ability to easily deploy and leverage the enhanced features and functionality of the award winning Catalyst Series Switches while eliminating the costs of rewiring. Evolving the Catalyst 2900 LRE Series, Catalyst 2950 LRE switches include the Catalyst 2950 Enhanced Image enabling the same Quality of Service (QoS), High Availability and Security found in existing Catalyst 2950 Series Switches. The new Catalyst 2950 LRE switches also features Gigabit Ethernet connectivity via either fixed 10/100/1000 ports or SFP ports.

Features

• 12 or 24 LRE ports, each delivering dedicated per-port symmetric bandwidth up to 5 Mbps (up to 5,000 feet), 10 Mbps (up to 4,000 feet) or 15 Mbps (up to 3,500 feet) over Category 1, 2, or 3 single-pair copper wiring to support advanced network services.
• Four 10BaseT/100BaseTX autosensing ports, each delivering up to 200-Mbps bandwidth to individual users, servers, or workgroups to support LRE switch daisy-chaining, aggregation or server/router connectivity.
• Full-duplex operation on all ports, delivering up to 15 Mbps on LRE ports and up to 200 Mbps on 10/100 ports 5-Gbps switching fabric and up to a 3.0-million- packets-per-second (Mpps) forwarding rate, ensuring high-performance forwarding to each LRE and 10BaseT/100BaseTX port
• 4-MB shared memory architecture, ensuring the highest-possible throughput with a design that eliminates head-of-line blocking, minimizes packet loss, and delivers better overall performance in environments with extensive multicast and broadcast traffic
• Dual-priority forwarding queues on each LRE and 10/100 port, enabling network traffic prioritization and seamless data, voice, and video integration through the IEEE 802.1p protocol
• Bandwidth aggregation through Fast EtherChannel technology, enhancing fault tolerance and offering up to 400 Mbps (10/100 ports) of aggregated bandwidth between switches, and to routers and individual servers
