Usage Guidelines

Usage Scenario

Sync packets are used to transmit clock information between a server and a client.

Prerequisites

1588 ACR/ATR has been enabled.

Configuration Impact

If the ptp-adaptive request sync-interval command is run for multiple times, the latest configuration of this command overrides the previous one.

Precautions

This command is supported only on the admin VS.

This command is used on clients only.

This configuration needs to be performed before enabling unicast negotiation. If this configuration needs to be modified, disable unicast negotiation first.

Example

# Set the interval at which the server sends Sync packets to 1s.
