Abstract
Various systems and method of preventing data traffic connectivity between endpoints of a network segment are disclosed. One method involves receiving a segment protocol message from a first segment port within a network segment, which includes a plurality of network devices. In response to receipt of the segment protocol message, which can indicate whether connectivity is present between the segment endpoints via the network segment, a second segment port can be operated in a blocked state. Operating the second segment port in the blocked state prevents data plane connectivity via the network segment.
