Abstract
Embodiments relate to forwarding of packets in link aggregation environments. A method for forwarding a packet through an extended switch including a first port extender and a second port extender directly or indirectly communicatively coupled to respectively a first interface and a second interface of a controlling bridge includes, associating a first port extender interface of the first port extender with a global namespace or an interface-specific namespace. The method further includes receiving a packet through the first port extender interface, marking the received packet with an indication of the namespace configuration of the first port extender interface, processing the marked packet in the controlling bridge based at least in part upon the indication, and transmitting the processed packet out of the controlling bridge.
