configure network-clock gptp ports sync
Description
Configures gPTP synchronization parameters on the specified ports.
Syntax Description
| 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. |
Default
- log_2_interval = -3 (0.125 second; 802.1AS 11.5.2.3)
- timeout_count = 3 (802.1AS 10.6.3.1)
Usage Guidelines
Synchronization 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.
Example
configure network-clock gptp ports 1-2 sync initial-interval -1 configure network-clock gptp ports all sync receipt-timeout 5
