Configuring Trunk Ports for Load Sharing
Configuring Load Sharing Using STP Port Priorities
If your switch is a member of a switch stack, you must use the spanning-tree [vlan vlan-id] cost cost interface
configuration command instead of the spanning-tree [vlan vlan-id] port-priority priority interface
configuration command to select an interface to put in the forwarding state. Assign lower cost values to
interfaces that you want selected first and higher cost values that you want selected last.
These steps describe how to configure a network with load sharing using STP port priorities.
