Enumeration
A clock may be administratively designated as part of a preferred master clock set. This creates a set of clocks that will be favored over those not so designated in the selection of master clocks within a subdomain. The purpose of this designation is to allow users to specify a clock that will remain master in the presence of disconnection or connection of other clocks.
