How can I configure a backup IP address for a member CE switch in a stack

If a backup IP address is configured for a stack member switch and the switch fails the DAD competition after a stack split, the switch switches its IP address to the backup IP address to prevent conflict with IP addresses of other switches. You can then remotely log in to the switch to locate and rectify faults.
