If this command is used without specifying a clock source port, and
◆
SyncE has not been enabled on any port, then the local clock is set to
be the active clock source.
If SyncE has been enabled on more than one port, the switch will
◆
choose the clock source port based on the current clock source port
status and priority.
A port can be forced to be the clock source port regardless of the
◆
clock's signal status.
