I have a fibre link and LAN cable directly connecting switch1 and switch3 and also another connection going from switch1 to switch3 via switch2 using LAN cables.
I want to have Link Aggregation Group(LAG) at switch1 for the 3 ports (2 directly connecting to switch3 and one through intermediate switch2) for getting higher bandwidth and failover redundancy for switch3.
Q1- Is it possible to have LAG with the indirect connection through switch2 as shown in the figure?
Q2- How would I configure LAG for ports @ switch1? (If you point me to exact commands or any resources links, it would be helpful)
Q3- Do I need to configure LAG @ switch3 also for corresponding ports?
Q4- What modes(active/passive/on) should I use for LACP @ switch1 and @switch3?
