virtual network environment's loop possibility

Posted on 2011-10-11

I have one ESXi server and there are two L2 switch in my office.
Let's say, switch_A and switch_B.
switch_A is a Core L2 switch and switch_B is placed under switch_A.
This means switch_B's uplink is switch_A.
Physically, Switch_A and switch_B is connecting vertically.

I have one  ESXi server which has 6 ethernet nic.
if I connect 3 ethernet between Esxi server and Switch_B and 3 ethernet between Esxi server and Switch_A,
the broadcast storm could happen?
I don't use any trunk nor Etherchanel settings between Esxi server and L2switch.

Best regards

    Hi Shouichi, No it wouldn't. Ideally, it would be recommended that you set up a trunk. But if you are not using any vlans within vmware etc, you could connect 3 ports to switch a and 3 to port b to maintain your redudancy for swithc failures. trunking will allow you to aggregate the links and create a fat pipe as well. just something to consider
