[Usage Scenario] Synce is a synchronization technique based on carrying and recovering frequency information from physical layer code streams. The implementation confirms through an election whether the device uses its own crystal frequency or the crystal frequency obtained from the peer-to-peer interface.
[Use Cases]
sonic(config)# interface ethernet 1
sonic(config-if-1)# synce enablesynce mode {master|slave}
[Command] synce mode {master|slave}
[Purpose] Configure the synce mode of interface to master or slave
[Parameter]
Parameter | Description |
|---|---|
master | Clock signal sender |
slave | Clock signal receiver |
[View] Interface view
[Usage Scenario] The default synce mode is master. The synce mode is recommended to be the same as the PTP mode on interafce
[Use Cases]
sonic(config)# interface ethernet 1
sonic(config-if-1)# synce mode slavesynce priority
[Command] synce priority value
[Purpose] Configure the synce priority of interface
[Parameter]
Parameter | Description |
|---|---|
value | Value range:0 to 255 |
[View] Interface view
[Usage Scenario] When more than one interface is present to enable synce, the interface with the highest priority is selected.
[Use Cases]
sonic(config)# interface ethernet 1
sonic(config-if-1)# synce priority 1
