Say have a network physically connected in a star with the center a 4500 switch. Off of the 4500, I have several switches all connected via one pair fiber. Now I have one 3560 switch that has two fiber trunks back to the 4500 and that switch has two copper ports that I want to dedicate full bandwidth of one of the fiber ports for traffic back to the core (leave all other ports going to the other fiber).
The only way I can think of forcing traffic is to set the two ports on a different VLAN and exclude that VLAN from one of the fiber trunks.
Is this possible without setting up a different VLAN for these two ports?
