Daisy-chaining Support

Both switches connected in daisy-chained mode must have the IP address in the same subnet, and the appliance must be able to reach this subnet. Provisioning the switches in daisy-chained mode is a two-step process:

1. Provision the parent switch as a standalone switch.
2. Provision the child switch as a daisy-chained switch.
