I have 4 Cisco 3750X's connected via stacking cables. The last switch in the stack, does not see itself as a member of the stack for some reason. I've verified that the cabling is correct and rebooted the stack several times but the problems persist. The switch will boot up, call itself the master (even though there is already another master) and then it looks like it reboots. It keeps going through this cycle. Any ideas?
