High-availability features such as Ether Channel & Flex Links will work across stack members, increasing uptime & network connectivity. Flex Stack-Plus is an improvement over Flex Stack because it doubles the speed of the stack bandwidth & allows for more members to join the stack. The Flex Stack-Plus bandwidth for a single stack member is 40 Gbps compared to 20 Gbps with Flex Stack. With multiple stack members, the Flex Stack-Plus bandwidth is 80 Gbps.
