I have a stack of 3 3750 switches. The switch is configurd as a layer 3 switch, routing over eigrp to other switches. Should I disable stp on the 3750 stack switch. I have IP Phones, LWAP's & pc host connected to the 3750 stack.
What is the advantage/disadvantage of disabling STP? What i Cisco 'best pratice'?
Personally i would not disable STP on a switch even if you think it is not needed. If you do not have any L2 loops then leaving STP on is not doing you any harm. And if someone accidentally connects something up that creates a L2 loop you still have STP to protect you.
Better to be safe than sorry in my opinion.
