We had a switch go out this week (a layer three switch) and we replaced it with another one (layer two). Both switches are 3560 PoE. The switch that was lost was the VTP server. When we yanked it out and put the new switch in, the two other switches in that network 'took' the VTP server role, which has caused some issues. The original issue was a failed inline power. After discovering the issue of the VTP mode changing, we changed both back to clients. It keeps rolling back to server. Any thoughts on this?
