Usage Guidelines During normal operation, the reference clock is selected based on an algorithm that uses the priority
rankings that you assign to the input clocks by using the network-clock-select priority priority global
configuration command.
The reference clock source can be the BITS input or a PHY-recovered clock from one of the uplink ports.
The ME 3800X and ME 3600X switch supports a BITS port through an RJ45 connector.
