Gigabit stackable switches on tap from Cisco

Cisco Systems continued its Gigabit Ethernet push this week with an update to its stackable aggregation switch, as well as a Gigabit Ethernet box for desktop links.

The Catalyst 3750-12S includes 12 fiber-based Gigabit ports. It can be linked with up to eight other 3570 series switches using Cisco’s StackWise technology to create a high-speed ring.

The 24-port Catalyst 2790G-24T is targeted as a LAN edge switch, with 10/100/1000M bit/sec ports, each supporting quality-of-service controls. Both switches could help enterprises add faster and more intelligent pipes to their LANs, the company says.

StackWise was introduced in April along with the Catalyst 3750 series. It allows stackable Gigabit Ethernet switches to be linked in a 32G bit/sec ring to provide fast failover and high-speed uplinks to wiring closet switches, Cisco says. The Catalyst 3750-12S provides 12 fiber-based Gigabit ports, and could be used as an aggregation-layer switch, connecting wiring closet boxes back to a LAN core. The switch also comes with Cisco’s Cluster Management Suite software, which can be used to configure, manage and monitor StackWise clusters.

The Catalyst 2790G-24T is aimed at wiring closets in enterprises with an eye to a future that includes Gigabit to the desktop. With support for three speeds of Ethernet, the switch could be deployed to support 10/100M bit/sec users now and Gigabit Ethernet desktop users down the road.

The Catalyst 3750G-12S is available now for US$8,000, and the Catalyst 2970G-24T will be available at the end of this month for $5,500.
