FCoE: Link aggregation group

Enables you to transport FCoE traffic and regular Ethernet traffic across the same link aggregation bundle. Fibre Channel (FC) storage area network (SAN) switches require a point-to-point connection. Communication between an FCoE device and QFabric system Node device must use the same physical LAG link to maintain that (virtual) point-to-point connection. Standard LAGs can place traffic on any LAG link and therefore do not work for FCoE traffic, because a response from the FC SAN might return on a different link than the FCoE device used to send the request to the FC SAN. FCoE LAGs always use the same LAG link to send and receive traffic between a given FCoE device and a Node device. FCoE LAGs provide this special treatment for FCoE traffic, while at the same time handling regular Ethernet traffic normally, so Ethernet traffic enjoys the usual LAG benefits of load balancing and link redundancy. FCoE LAGs do not provide load balancing or link redundancy for FCoE traffic, but they do ensure that FCoE traffic uses the same link to communicate with the FC SAN through the QFabric system Node device LAG
