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, 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.
Note: 1pps and 10MHz signals are available only when PTP is enabled.
