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.
Note: 1pps and 10MHz signals are available only 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, 7210 SAS-R12, 7210 SAS-Sx 1/10GE
(standalone), and 7210 SAS-T devices.
On the 7210 SAS-R6, the G.8275.1 profile is supported only for IMMv1 and
IMMv2 cards.
On the 7210 SAS-R12, the G.8275.1 profile is supported only for IMMv2 cards.
When using the G.8275.1 profile, the following restrictions apply.
- The delay and sync requests are set to 16 pps by default and are not
configurable.
- The announce rate is set to 8 pps by default and is not configurable.
- A change of profile to G.8275.1 or from G.8275.1 to another profile requires
a reboot of the node.
- Only a single multicast slave is supported per port.
• PTP with Ethernet encapsulation is supported only with the G.8275.1 profile.
• PTP over IP encapsulation is not supported with the G.8275.1 profile. It is
supported only with the IEEE 1588v2 and G.8265.1 profiles.
• PTP slave capability is available on all the ports on the 7210 SAS-M,
7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-Sx 1/10GE, and
7210 SAS-T.
