mad restore Required
NOTE:
For a switch that transitioned to recovery state due to the multi-active collision, if you need to bring up one
of its port that are already shut down, H3C recommends that you execute the mad restore command to
recover the switch and make it operate in the active state instead of executing the undo shutdown
command to perform a manual recovery.

If a member switch has only one MPU and that board is corrupted, use the following fast recover function
to avoid complicated IRF configuration.
Configuration prerequisites
• H3C recommends that you perform the fast recovery operation when the switch operates in IRF
mode.
