Allied Telesyn International Corp. recently released a 24-port Layer 2 switch aimed at making LAN switch stacking easier.
The AT-8024GB offers 24 ports of 10/100M bit/sec Ethernet, plus two gigabit interface converter (GBIC) slots and can be stacked with up to 24 other AT-8024GBs without additional stacking modules or components. That makes the device a good candidate for a large-scale enterprise wiring closet switch, the company says.
Multiple switches in a stack can be managed as one logical device with a single IP address.
Software in the new switch allows it to be deployed in "virtual stacks" which can be configured through a telnet session. A management tool on the switch allows up to 624 total ports in a virtual stack to be monitored and configured centrally.
In typical stacking configurations, switches are limited to where they can be placed by the length of the stacking cables and add-on equipment, which often requires the switches to be located within a couple inches. The stacking software allows AT-8024GBs to be located as far away as a LAN connection can reach, but still managed along with other switches in a stack as a single node.
In addition to its virtual stacking capability, the Layer 2 switch supports all standard Ethernet switch features, such as 802.1p priority queuing and 802.1Q virtual LAN tagging, as well as Auto-MDI/X for allowing switch-to-switch, or switch-to-client connections to be plugged into any port without worrying if cables terminated as crossover or standard.
The AT-8024GB is available now and costs US$1,140. GBICs are available for $470 and $1,140 for multi-mode or single-mode fiber connections.
