I'm going to setup n.4 DELL N1548 switches; they are linked throught uplink ports (10GB) as you can see in the image attached. There are n.3 servers; each server has n.2 NICs mounted using bonding mode 6 (balance-alb - Adaptive Load Balancing ) linked to 2 different switch.
Could you give me some advices on how to configure a redundant scenario with those switches ? STP, LACP, routing, etc
