Claim Text:
1. A computer-implemented method comprising: receiving, via a receiving non-fabric port on a receiving switch located on a network fabric, a miscabling protocol packet indicating an identity of an originating switch on the network fabric and an originating non-fabric port associated with the originating switch, wherein the miscabling protocol packet is received from an external network connected to the receiving non-fabric port, wherein the originating switch and originating non-fabric port are also located on the network fabric and connected to the external network, wherein the receiving non-fabric port and the originating non-fabric port are both: based on the miscabling protocol packet, detecting a loop between the receiving port, the originating port, and the external network; and blocking at least one of the receiving port and the originating port associated with the miscabling protocol packet in response to detecting the loop.
