• peer-to-peer transparent clock
Table 30: Synchronization options for 7210 SAS platforms lists the 7210 SAS platform support for the
different types of PTP devices.
The 7210 SAS communicates with peer 1588v2 clocks, as shown in the following figure. These peers can
be ordinary clock timeReceivers or boundary clocks. The communication can be based on either unicast
IPv4 sessions transported through IP interfaces or Ethernet multicast PTP packets transported through an
Ethernet port.
