You can define a policy for the outgoing traffic that specifies how to distribute load across the available links of an aggregation, thus establishing load balancing. You can use the following load specifiers to enforce various load balancing policies:
L2 – Determines the outgoing link by using the MAC (L2) header of each packet
L3 – Determines the outgoing link by using the IP (L3) header of each packet
L4 – Determines the outgoing link by using the TCP, UDP, or other ULP (L4) header of each packet
Any combination of these policies is also valid. The default policy is L4.
