configure network-clock gptp ports sync
Configures gPTP synchronization parameters on the specified ports.
|port_list||Specifies one or more of the switch's physical ports.|
|only||Apply change only to specified port, even if port is master of a load sharing group.|
|all||Specifies all of the switch's physical ports.|
|log_2_interval||The interval between Sync messages used by the switch for the port when the port is initialized or when the switch receives a message interval request TLV with timeSyncInterval value of 126. This value is in log2 seconds. The valid range of values is -3 (2-3 = 0.125 seconds) to 17 (217 = 131072 seconds).|
|timeout_count||On a gPTP slave port, the number of sync intervals to wait without receiving a Sync message before assuming the adjacent master port is no longer sending Sync messages.|
- log_2_interval = -3 (0.125 second; 802.1AS 188.8.131.52)
- timeout_count = 3 (802.1AS 10.6.3.1)
Usage GuidelinesSynchronization distributes the time from the grandmaster to all other time-aware systems in the networks.
initial-interval corresponds to 802.1AS parameter initialLogSyncInterval.
receipt-timeout corresponds to 802.1AS parameter syncReceiptTimeout.
