Description/Notes
This utility calls the kernel to modify an MDM’s IP address list. It is typically used in
cases when an MDM IP address has changed, or when MDMs are added/removed
from/to the system. The command must be run on every SDC in the system. To bring
the changes into effect, a server restart is required.
