Single Ring Topology

Single ring topology shows a single ring topology with normal data flow, data flowing in two directions from the ring master when a link is broken, and the restoration of normal data flow after the link comes back online.

Single ring topology

The single ring topology supports ring-master and ring-slave options.

Ring - Each switch can be master or slave.

• When the switch's role is ring master, one ring port is the forward port and another is the block port. 
The block port is a redundant port. In normal state, it is blocked.
• When the switch's role is ring slave, both ring ports are forward ports.
