I've been having a few issues building a stack of 7x 3750v2's. I've configured the first switch as master, provisioned the other 6 switches, set lower priorities for the other switches and made sure all are using the same ios. (c3750-ipservicesk9-mz.122-55.SE)
When I plug them in one at a time, they all come up fine with the correct stacking number. The master even moves to the next highest priority if the master is powered off. However if the stack is rebooted, then all the switches load with either a different switch number or as part of a different stack.
I've checked all the stacking cables are correctly plugged in, though the stack would not have worked correctly in the first place if they were not.
Anyone have any ideas what else I can try to get this working?
Ive got a reported fault with the exact same issue. Im due to go in and have a look at it tomorrow but was wondering if you managed to resolve the issue.
