Abstract:
An information handling system may include at least one processor; and a memory; wherein the information handling system is configured to manage a network that includes a first virtual link trunking (VLT) node, a second VLT node, and a plurality of devices that are communicatively coupled to the first VLT node via a first set of links and to the second VLT node via a second set of links, wherein the managing includes: detecting that the first VLT node has malfunctioned; detecting that the first VLT node has recovered; and after the first VLT node has recovered, preventing traffic over the first set of links until determining that all information needed to forward the traffic has been synced between the first VLT node and the second VLT node.
