Load Balancing

Load balancing builds on the Automatic Trunking functionality by specifying the path that the data uses to flow between multiple switches. Users can manage the switch’s aggregate bandwidth by manually distributing traffic across multiple cascade ports as shown below. A cascade port is a port that is attached to another switch of the same type and configured as a String or Tree Cascade Smart Setting on the Port Smart Settings page. All data flows through the primary cascade, unless the switch is configured differently.

Note: Cascade ports must be properly configured before load balancing will work.
