Re: OT 3750-X

Guys

say the power does not fail, but the actual control-plane/data-plane fails
on the master switch which has all the devices connected, how would the
member take the master role & continue forwarding traffic, so this would be
a non power failure but a failure of the control-plane

Thanks

Tony
