Q

Which of the following statements regarding selection of active links in LACP mode are false?
A - In static LACP mode, after joining the Eth-Trunk, the member interfaces send the system priority, system MAC address, interface priority , and interface number to the remote end to negotiate active interfaces
B - A larger LACP system priority indicates a higher priority. The end with a larger LACP system priority
functions as the active side. If the two ends have the same LACP system priority, the end with a larger MAC address functions as the active side
C - The passive side determines active interfaces based on the LACP priority and ID (interface number ) of
an interface on the active side
D - Data can be forwarded normally even if both devices select different interfaces.

Which of the following statements regarding the static LACP mode are false?
A - If a high bandwidth of the link between two directly connected devices is required but the remote device does not support LACP, you can use the manual load balancing mode
