Extreme releases lower-cost switches

Extreme Networks is now shipping 24- and 48-port Summit 200 10/100 Ethernet switches.

The Summit 200 switches operate at Layer 3 of the Open Systems Interconnection (OSI) model, offering more intelligence for network security and performance, said John Erlandson, director of hardware product management at Extreme Networks.

Both are rack unit designs and, at $1,850 for the 24-port model and $3,350 for the 48-port model, are "less expensive than many Layer 2 switches" with less intelligence, Erlandson said. Layer 2 is the data link layer in the seven-layer OSI model.

Erlandson added that the Summit 200 represented "the end of the Layer 2 switch" because of its Layer 3 intelligence and low cost.

Last week both Cisco Systems and Nortel Networks unveiled lower-cost switches

Cisco launched several Lan switching products which included the Catalyst 4500 Series Supervisor Engine II-Plus, a control module that fits into the Catalyst 4500 switch series chassis. Designed for smaller networks, it provides quality of service and security for wireless connections and IP telephony.

Cisco also introduced the new Catalyst 4500 48-port 10/100/1000 module, which is designed to reduce the cost of Gigabit Ethernet while providing power over Ethernet. It is available now for $5,495.

Another new Cisco product, the Catalyst 2970 Series 24-port fixed configuration switch, is designed to offer Gigabit Ethernet connectivity. It's priced at $4,995.

Nortel also announced two new BayStack 5000 switches and the Passport 8300 Ethernet switch last week. The BayStack 5000 switches are designed to offer greater intelligence and performance for distributed applications and the ability to bring Gigabit Ethernet to desktops.

The switches feature improved stacking that will enable them to run 32 times faster than preceding models, Nortel officials said.
