Sets and saves the external clock synchronization mode of the external
clock source port. You are prompted to specify an external clock source
port. This can only be used with an 8-port interface card. All other
bottom ports on this and other 8-port boards in the chassis will be
synchronized according to the external clock source port. The OC-12 card
cannot synchronize a clock on an OC-3 port.
It is not possible to synchronize ports unless there is a fiber optic cable in
the port.
