An environment consists of a Cisco MDS 9000 Series Switch that uses port channels. An engineer must ensure that frames between the source and the destination follow the same links for a specific flow. Subsequent flows are allowed to use a different link.
Which load balancing method should be used to accomplish this goal?
- A . src-id/dst-id
B. src-dst-oui
C. src-dst-port
D. src-id/dst-id/oxid
Suggested Answer: D
Explanation:
Exchange based―The first frame in an exchange picks a link and subsequent frames in the exchange follow the same link. However, subsequent exchanges can use a different link. This provides more granular load balancing while preserving the order of frames for each exchange.

Load balancing attributes indicate the use of the source-destination ID (src-dst-id) or the originator exchange OX ID (src-dst-ox-id, the default) for load balancing path selection.
