Cisco Stack Wise-480 technology is built on the highly successful industry-leading Stack Wise technology, which is a premium stacking architecture. Stack Wise-480 has a stack bandwidth of 480 Gbps. Stack Wise-480 uses Cisco IOS Software SSO for providing resiliency within the stack. The stack behaves as a single switching unit that is managed by an "active" switch elected by the member switches. The active switch automatically elects a standby switch within the stack. The active switch creates & updates all the switching/routing/wireless information & constantly synchronizes that information with the standby switch. If the active switch fails, the standby switch assumes the role of the active switch & continues to the keep the stack operational. Access points continue to remain connected during an active-to-standby switchover. A working stack can accept new members or delete old ones without service interruption. Stack Wise-480 creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single Telnet session, single CLI, auto-version checking, auto-upgrading, auto-configuration, & more. Stack Wise-480 also enables local switching in Cisco Catalyst 3850 Series Switches. ...
