The value flows through network_server.ml:1142-1155 to Ovs.create_bridge, which sets other_config:disable-in-band=true on the OVS bridge. Disabling in-band management severs SDN controller connectivity when no out-of-band path exists. The field has no map_keys_roles entries for infrastructure keys."
