Stackable switches can be connected in a daisy-chain topology. This is a ring topology with one of the links disconnected, inoperative, or disabled. A daisy chain can be created when a link fails or a node reboots in a ring topology, but the daisy chain topology is not recommended for normal operation.
We strongly recommend that your stack nodes be connected in a ring topology, not a daisy-chain topology, for normal operation.
In Daisy-Chain Topology, the nodes delineated as the active topology are operating in a daisy-chain configuration, even though there is physically a ring connection in the stack.
You might need to use a daisy chain topology while adding a new node, removing a node, or joining two stacks.
If you are using a daisy chain topology, the possibility of a dual master condition increases. Before you create a daisy chain topology, read Managing a Dual Master Situation.
