Configuration to change reference from SyncE to PTP on 7210
SAS-M and 7210 SAS-X
On 7210 SAS-M and 7210 SAS-X, use of PTP and SyncE as a reference simultaneously is not
allowed. The user can configure either SyncE as a reference or PTP as a reference, but not both
together. The following are the configuration steps to change reference from SyncE to PTP. This
procedure is required only on 7210 SAS-M and 7210 SAS-X nodes.
1. Initially for Standalone PTP:
configure >system >ptp >no shutdown
config> system> sync-if-timing> begin
config> system> sync-if-timing> commit
Note: Now the Frequency and Time is provide by PTP only.
2. To changeover to use syncE the following must be executed:
7210 SAS M, T, X, R6 Basic System Configuration Guide
The 7210 SAS-M and 7210 SAS-X nodes uses CPU processing cycles for frequency and
time recovery.
7210 SAS-M and 7210 SAS-X support PTP hybrid mode of operation. In PTP hybrid
mode, SyncE is used for frequency recovery and PTP for time recovery. PTP Hybrid
mode allows the node to recover very stable frequency using SyncE and recovers time
using reduced PTP packet rate. It reduces the amount of CPU processing cycles needed,
helping customers to scale better.
7210 SAS-T does not support PTP hybrid mode.
On 7210 SAS-M it is highly recommended to use PTP only in hybrid mode. It allows
customers to use reduced PTP packet rates on these platforms and scale better.
On 7210 SAS-T, an IP address must be configured under "configure> security> source-
address> application ptp", before PTP can be enabled for use. It is recommended to use
System IPv4 interface address or other loopback IPv4 interface address for PTP
applications. User can also specify IPv4 address of an IPv4 interface over a port.
The 7210 SAS-T PTP software uses the configured IP address as the source IP address for
both configured peers and discovered peers.
