NOTE:
To avoid IP address collision and network problems, configure a minimum of one multi-active
detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle
collisions. For more information about MAD detection, see H3C S6520X-SI Switch Series IRF
Configuration Guide or H3C S6520X-SI Switch Series Virtual Technologies Configuration Guide,
depending on the software version.
