configure network-clock gptp ports sync

configure network-clock gptp ports [port_list {only} | all] sync [initial-interval log_2_interval receipt-timeout timeout_count]

Description

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.

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.

configure network-clock gptp ports 1-2 sync initial-interval -1
configure network-clock gptp ports all sync receipt-timeout 5
