Abstract
Devices and techniques are generally described for loop detection failsafe in Ethernet networks. In some examples, a first set of networked devices employing a loop-prevention protocol may be determined. A first device of the first set of networked devices may be identified. The first device may include at least a first port and a second port. In some examples, it may be determined that the loop-prevention protocol has assigned a forwarding state to the first port. It may be determined that an application of the loop-prevention protocol assigns a non-forwarding state to the second port. In some examples, a determination may be made that the second port forwards network traffic. In various examples, a network link associated with the second port may be disabled.
