What is the difference between Flex Stack, Flex Stack Plus, Flex Stack Extended, Flex Stack Extended Hybrid?

Flex Stack:

--> FlexStack technology works only on Cisco Catalyst 2960S series switches.

--> FlexStack technology allows you to connect up to 4 switches in a single stack.

--> In order to use FlexStack Technology Cisco 2960S switches uses a special module C2960S-STACK and a special cable CAB-STK.

--> Each stack cable can send data at a speed of 10 Gbit/s.

--> The total stacking bandwidth of the stack is 40 Gbit/s.

--> Every FlexStack module supports only two FlexStack ports.

--> FlexStack protocol used by stack members to communicate with Each other.

--> FlexStack protocol is used to detect new switch additions as well as existing switch removals.

Flex Stack Plus

--> FlexStack Plus technology works with Cisco Catalyst 2960X and 2960XR series switches.

--> FlexStack technology allows you to connect up to 8 switches in a single stack.

--> In order to use FlexStack Plus Technology, Cisco 2960X switches uses a special module C2960X-STACK and a special cable CAB-STK.

--> Flex Stack Plus supports stacking cables up to 10 ft.

i) CAB-STK-E-0.5M = 1.5ft cable

ii) CAB-STK-E-1M = 3 ft cable

iii) CAB-STK-E-3M = 10 ft cable




--> The total stacking bandwidth of the stack is 80 Gbit/s.

--> Every FlexStack Plus module supports only two FlexStack ports.

--> Flex Stack Plus is compatible with Flex Stack.

--> It is possible to stack mix of the 2960S and 2960-X using Flex Stack and stack bandwidth is limited to 40 Gbps because of Flex Stack.

Flex Stack Extended

--> FlexStack Extended technology works with Cisco Catalyst 2960X and 2960XR series switches.

--> FlexStack Extended technology allows you to connect up to 8 switches in a single stack.

--> In order to use FlexStack Extended Technology, Cisco 2960X switches uses a special module C2960X-FIBER-STK and SFP cable.

--> FlexStack Extended Module allows combining of Cisco Catalyst 2960X series switches over long distances.






--> It can be used to stack the switches on different floors in the same building or between different buildings.

--> The total stacking bandwidth of the stack is 40 Gbit/s.

--> FlexStack Extended Module contains two SFP+ ports.

--> FlexStack Extended Module is not compatible with Flex Stack.

Flex Stack Extended Hybrid Module

--> FlexStack Extended Hybrid technology works with Cisco Catalyst 2960X Series Switches.

--> FlexStack Extended Hybrid technology allows you to connect up to 8 switches in a single stack.

--> In order to use FlexStack Extended Hybrid Technology, Cisco 2960X switches uses a special module C2960X-HYBRID-STK and it uses SFP cable as well as stack cable.

--> SFP Ports are used for stacking the switches over long distances.




--> Flex Stack Extended Hybrid technology supports stacking cables up to 10 ft.

i) CAB-STK-E-0.5M = 1.5ft cable

ii) CAB-STK-E-1M = 3 ft cable

iii) CAB-STK-E-3M = 10 ft cable

--> The total stacking bandwidth of the stack is 40 Gbit/s.

--> FlexStack Extended Hybrid Module contains one SFP+ port and one stack port.

--> FlexStack Extended Hybrid Module is not compatible with Flex Stack.
