The 7210 SAS-R6 and 7210 SAS-R12 devices, uses the packet header fields that computes the hash for unicast traffic to be sent out of a SAP configured over a LAG and forwards it over the member ports of the LAG. For unknown unicast, broadcast and multicast traffic, it does not compute a hash and forwards all traffic out of the primary port of the LAG. For more information, see the 7210 SAS-Mxp, R6, R12, S, Sx, T Interface Configuration Guide.
