Clock Priority Chain Level Systems and Methods are provided. In one embodiment, a method for determining clock priority for a multihost unit distributed antenna system is provided. The method comprises identifying which port of a plurality of ports is receiving a reference clock signal having a highest priority Network Chain Level (NCL) value, wherein the highest priority NCL value indicates a master clock priority level (MCPL) of a host unit providing a Master Clock and a chain level value indicating a chain depth; selecting a system clock reference port from the plurality of ports based on the highest priority NCL value; locking a local clock to a reference clock signal received on the selected system clock reference port; calculating an incremented NCL value based on the highest priority NCL value; and transmitting the incremented NCL value over the plurality of ports.
