The amount of appliance to form a logical switch. 

 

VSS = Maximum two chassis.  Only for 4500 & 6500/6800 switches.

Stack = Maximum nine appliances.  2960S/X/XR, 3750, 3650, 3850.

Dear Leo,

Thanks for the reply. Is there any method like one of the control plane will be active and all the data plane is in forwarding state in stacking technology?
