Cisco flexstack and flexstack-plus stacking for cisco catalyst 2960-s. 2960-X and 2960-xr series switches provides a true stacking solution. With all switches in a flexstack or flexstack-plus stack acting as a single switching unit. Flexstack and flexstack-plus provide a unified data plane and single configuration for a group of stacked cisco catalyst 2960-s. 2960-X. And 2960-xr switches. Flexstack and flexstack-plus lower the total cost of ownership with built-in 1:n redundancy. High availability. And preprovisioning. Not available in standalone switches. High-availability features such as etherchannel and flexlinks will work across stack members. Increasing uptime and network connectivity. Flexstack-plus is based on flexstack. Flexstack was introduced on the 2960-s in 2010. Flexstack-plus is being introduced in 2013 with the 2960-x and 2960-xr models of cisco catalyst ethernet switches. Flexstack-plus is an improvement over flexstack because it doubles the speed of the stack bandwidth and allows for more members to join the stack. The flexstack-plus bandwidth for a single stack member is 40gbps compared to 20gbps with flexstack. With multiple stack members. The flexstack-plus bandwidth is 80gbps. And the flexstack bandwidth is 40gpbs. With flexstack-plus technology. Eight 2960-x or xr members can be joined into a single stack. With flexstack only four 2960-s members could be joined into a single stack. Flexstack-plus is backward compatible with 2960-s and flexstack. Mix...
