Abstract:
1. A method, comprising: detecting, by a first network device, a configuration problem at a second network device, the first and second network devices being associated with a link aggregation group (LAG) coupling the first and second network devices, wherein the first network device includes a first port connected to a first link in the LAG and a second port connected to a second link in the LAG, wherein the first link in the LAG and the second link in the LAG are each connected to the first and second network devices, wherein the detecting a configuration problem comprises: de-activating, by the first network device, at least the first link in the LAG in response to detecting the configuration problem; maintaining at least the second link in the LAG as an active link; allowing traffic to be forwarded to the second network device from the second port of the first network device via the second link in the LAG; receiving, by the first network device and from an interface device coupled to at least one link in the LAG, a first message instructing the first network device to terminate transmission via the first link in the LAG; and receiving, by the second network device and from the interface device, a second message instructing the second network device to terminate transmission via the first link in the LAG.
