Abstract
A method, an information handling system (IHS) and a switching system for preventing communication loops in an IHS. The method includes identifying, via a controller, at least one stacking port in a first switch of a first chassis. The first switch is in communication with a second switch of a second chassis via a first link. At least one stacking port is configured as an unblocked port. Port blocking and unblocking actions are determined for the at least one stacking port. The at least one stacking port is configured based on the determined port blocking and unblocking actions and a determination is made if the first chassis is a root bridge chassis having at least one uplink port. In response to the first chassis being a root bridge chassis, a first uplink port in the first switch is configured as an unblocked port.
