Nexsus load balancing mechanism for FcoE Mappings

On the Nexus 5000, the default load balancing mechanism on the LACP port-channel is source-destination. If we leave it in this state, all the FCoE traffic will take the same link in the port channel when the Nexus 5000 is forwarding frames to the upstream device.

To enable the Nexus 5000 to load balance using exchange IDs, we configure it for ‘source-dest-port’ load balancing.
