Abstract
A system and method for ingress port identification in aggregate switches includes a network switching device including a controller, a first port coupling the network switching device to another network device, and one or more forwarding information tables being maintained by the controller. The network switching device is configured to receive a first packet at the first port, replicate the first packet, insert a first reserved ingress ID associated with the first port into the replicated first packet, and forward the replicated first packet to a first peer switch. The network switching device is part of an aggregate switch.
