This object indicates whether the physical MGMT port is being used to manage this specific unit directly (local) or is instead passing management traffic through to a different, remote unit. It matters on chassis systems with multiple modules or shelf controllers, since a technician plugging into a MGMT port expecting to reach this unit's own console needs to know whether that port actually terminates locally or forwards elsewhere. For example, remote(2) on an I/O module's MGMT port means it's relaying traffic up to a shared control module rather than exposing management access to the I/O module itself.
