Cisco Offers More Resilient Stackable Switches
Next-generation stackable switch family emphasizes resiliency, ease of operation, performance and unified services.Cisco Systems Inc. Tuesday launched the next generation of its stackable switch family in a new line that emphasizes resiliency, ease of operation, performance and unified services. The new Cisco Catalyst 3750 series initially includes four new stackable switches for Fast Ethernet and Gigabit connectivity. The 24- and 48-port stackables use new Cisco StackWise 32-Gigabit-per-second interconnect technology that is integral to the data forwarding path of the multilayer switches. Earlier generations of stackables created interconnects as an afterthought, according to Kathy Hill, vice president and general manager of Ciscos desktop switching business unit in San Jose, Calif. "Being totally integrated with our data forwarding logic gives users the ability to simply manage additions and removals from the stack. If you need to add another switch in a branch office, anyone there can just add a new one by putting in a power cable and adding a new device. Any decisions youve already made, such as which software version youre running, will be maintained," she said.
Other configuration parameters such as VLANs and quality of service parameters are automatically loaded into a new switch when it boots up. Replacements for failed switches automatically load the configurations set up in the failed device.
