Outbound Traffic Distribution Across
Trunked Links

The two trunk group options (LACP and Trunk) use source-destination
address pairs (SA/DA) for distributing outbound traffic over trunked links.
SA/DA (source address/destination address) causes the switch to distribute
outbound traffic to the links within the trunk group on the basis of source/
destination address pairs. That is, the switch sends traffic from the same
source address to the same destination address through the same trunked link,
and may also send traffic from the same source address to a different desti­
nation address through the same link or a different link, depending on the
mapping of path assignments among the links in the trunk. Likewise, the
switch distributes traffic for the same destination address but from different
source addresses through links depending on the path assignment.
