Example configuration for the FortiSwitch-5003A board in slot 2

The FortiSwitch-5003A board in slot 2 requires the same configuration settings as the FortiSwitch-5003A board in slot 1 except that the priority values of both spanning tree instances is set higher for the FortiSwitch-5003A board in slot 2:

config switch fabric-channel stp instance edit 3

set priority 40960

set vlan-range 103-104 next

edit 5

set priority 40960

set vlan-range 105-106 end

Note: The priority values of both spanning tree instances should be higher on the FortiSwitch-5003A board in slot 2 than on the board in slot 1 so that spanning tree directs all traffic to the board in slot 1.
