The following table lists the synchronization options supported on 7210 SAS platforms.
The 7210 SAS supports the ordinary clock in timeReceiver mode and the boundary clock. The boundary clock and ordinary clock timeReceiver can be used for both frequency and time distribution and recovery. The 7210 SAS does not support ordinary clock in timeTransmitter mode or peer-to-peer transparent clock.
