I have a collapsed backbone design with a single C3570 G switch and 3 C3750 access switches.
I plan to have 2 uplinks from the access switches to core so I will stack the 3 access switches.
Q1. If the 3 access switches are stacked and if cross stack uplink fast is used. Will one of the 2 uplinks be blocking ?
Q2. If one of the uplinks in the stack is blocking, will I be able to configure vlan load balancing to get both the uplinks up ?
Q3. Should I use port cost to do the vlan load balancing ?
Any help appreciated.
