Cisco C2960S FlexStack-Plus - Network Stacking Module - No stacking Cable

Description

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. A single FlexStack connection between two members is a full duplex 10Gbps connecton. Each Cisco Catalyst 2960-S member supports two FlexStack connections. Each FlexStack member can simultaneously send and receive Ethernet traffic over both stack links at line rate, effectively giving 20Gbps of stack bandwidth per member. Up to four switches can stacked together using FlexStack to form a single logical switch. Logical switch is another term used to identify a stack of switches. There are multiple physical switches acting as a single unit. This single unit behavior is a logical switch. Cisco Catalyst 2960-S switches running FlexStack use a hop-by-hop method of transferring Ethernet packets across the stack. Packets traverse the stack by going from one member to another over the FlexStack links until the packet reaches its destination. This is the same behavior as multiple standalone Ethernet switches forwarding packets from one switch to another.
