6.5.10 1PPS and 10MHz Output Interface
The 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12 support 1PPS
and 10 MHz output interfaces. These interfaces output the recovered signal from the
system clock when PTP is enabled.
6.5.11 Configuration Guidelines and Restrictions for PTP
The following guidelines and restrictions apply for PTP configuration.
• On 7210 SAS devices, only a single profile (IEEE 1588v2, G.8265.1, or
G.8275.1) can be enabled for all PTP communications (both towards its master
and slave connections) at any point in time.
• The PTP G.8275.1 profile is supported only on the 7210 SAS-M,
7210 SAS-Mxp,7210 SAS-R6, and 7210 SAS-R12 devices.
On the 7210 SAS-R6, the G.8275.1 profile is supported only for IMMv1 and
IMMv2 cards.
