Abstract
A method, an information handling system (IHS), and a virtual link trunking (VLT) system for determining VLT ports to block and unblock in an IHS. The method includes calculating a forwarding table index for a local switch of currently active and inactive switch peers for a VLT port. A pre-determined forwarding table is retrieved from a memory containing a plurality of port blocking and unblocking actions for the switch peers. Current port blocking and unblocking actions are identified in the pre-determined forwarding table corresponding to the forwarding table index. Changes are determined between the previous port blocking and unblocking actions and the current port blocking and unblocking actions. The input/output (I/O) ports are configured for the local switch based on the determined changes in the port blocking and unblocking actions.
