This read-only value, 0 to 65535, reports the minor revision level of the CPQNIC-MIB, where an increment indicates minor additional support without changes to pre-existing information. A management application can safely continue interpreting existing objects the same way even as this minor version changes, since it only signals additions. For example, a minor revision bump might indicate a new optional object like an IPv6 address field was added without altering any existing object's meaning.
