Abstract
A network of switches having ports coupled to other switches or end hosts may be controlled by a controller. The controller may identify whether any switch ports have failed. In response to identifying that a port has failed at a first switch, the controller may modify link aggregation group mappings of the other switches to handle failover. The controller may modify the link aggregation group mapping of each other switch to include a first mapping that includes ports coupled to the first switch and a second mapping that does not include any ports coupled to the first switch. The controller may configure forwarding tables at the switches to forward network packets using the first or second mappings based on network topology information maintained by the controller.
