COMMAND USAGE
◆ Use this command to configure the clock source according to the SSM
Quality Level (QL), port priority (as defined under the synce ssm
ethernet command), and port number.
If the SSM QL received on more than one port is the same, the clock
source port is selected according to priority.
If SSM QL and priority are the same on more than one port, the lower
port number be chosen as the clock source port.
◆ If the clock source port has been manually configured (i.e., the active
clock source is locked), SSM clock source selection will not function.
