Synchronous Ethernet

◆
If the switch is changed from SSM mode to Manual mode, and a port
has been chosen as the active clock source in SSM mode, this port will
still be the active clock source in Manual mode. If no clock source port
has been selected in SSM mode, the local clock will be used as the
active clock source.
◆
If the switch is changed from Manual mode to SSM mode, and a port
has been chosen as the active clock source in Manual mode, this port
will no longer be the active clock source. All clock source ports
configured under Manual mode will be removed. The new active clock
source is determined as described under the first item in this section.
◆
If the switch is changed from Manual mode to SSM mode using the
no
form of this command, and a port has been chosen as the active clock
source in Auto mode, this port will be the active clock source in Manual
Mode. If there is no active clock source in Auto mode, the local clock
will be used as clock source in Manual mode. All ports configured as
clock source ports under Auto mode will be kept after changing to
Manual mode.
Link State Changes
◆
If an SSM-enabled port links up, the new active clock source is
determined as described under the first item in this section.
◆
If SSM-chose clock source port goes down, the switch will choose the
next clock source port as described under the first item in this section.
If no other port can be used as the clock source port, the local clock will
be used as the active clock source.
Joining a Trunk
◆
If an SSM-enabled port is added to a trunk, and the trunk is not
operating at 1Gbps (full duplex), this port will no longer process SSM,
and cannot be used a clock source port.

This command uses SSM to select the clock source according to the SSM
quality level, priority and port number. Use the no form to disable this
function.
