-b Declares a string binding (required). You must also specify an interface identifier (using the -i option). Each command accepts up to 32 -b options. The value has the form of an RPC string binding, without an object UUID, for example: -b ncadg_ip_udp:63.0.2.17[5347] Note that depending on your system, string binding delimiters such as brackets ([ ]) may need to be preceded by an escape symbol (\) or placed within quotation marks (' ' or " "). Requirements vary from system to system, and you must conform to the usage rules of a system. -i Declares an interface identifier (required). Only one interface can be removed in a single operation. The interface identifier has the following form: interface-uuid,major-version.minor-version
