300-610 · Question #327
Refer to the exhibit. A 4x10G Fibre Channel has been configured between SW1 and SW2 to carry backup traffic sourced to and from the SAN. An engineer noticed that 10G Link 1 is being used more heavily
The correct answer is D. Configure exchange-based load-balancing.. Fibre Channel port‑channel load balancing relies on the FC “exchange” (OX_ID/DX_ID) to spread frames across member links. Enabling exchange-based hashing ensures backup traffic sessions are distributed evenly over all four 10 Gbps links.
Question
Refer to the exhibit. A 4x10G Fibre Channel has been configured between SW1 and SW2 to carry backup traffic sourced to and from the SAN. An engineer noticed that 10G Link 1 is being used more heavily than the other links within the port channel. Which action must the engineer take on the two switches to ensure that the traffic uses all available links between SW1 and SW2?
