Synchronous Ethernet
– 161 –
◆ This command can enable SyncE on trunk member but not on a trunk.
◆ SyncE can only be enabled on two ports at the same time.
Example
Console(config)#syncd ethernet 1/28
Console(config)#
synce ethernet clock-
source
This command manually sets a port as a clock source, or as a candidate clock source
at the specified priority when using automatic clock source selection. Use the no
form to remove a port as a clock source.

no synce synce ethernet unit/port clock-source
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-12)
priority - The priority used by automatic clock source selection.

Command Usage
◆ This command can enable SyncE on trunk member but not on a trunk.
◆ If more than one port is configured as clock source port with this command, the
first configured port will be set as the active clock source port.
◆ If an active clock source port is removed as the clock source, no active clock
source port will exist until explicitly configured.
◆ When no active clock-source port exists, the switch’s internal clock will be used
as the clock source.
◆ If the priority of the clock-source port is not specified, the port ID of the clock-
source port will be used as the priority for automatic clock source selection (see
the synce auto-clock-source-selecting command).
◆ Lower priority values indicate higher precedence. If more than two clock-
source ports have the same priority value, the clock source-port with the lowest
port ID assumes higher precedence.
