I have a 3750g-48 switch with static IP and 12.2.35 se2 ipservicek9 ios working fine. By mistake I connected another 3750g with the same IP address but with 12.2.44 se2 ios. they both have the same vlan. I shutdown the vlan on the new switch and the old switch went down. My question is that did the old one go down because I shutdown the vlan or because of IP address conflict?
