Usage guidelines
You can configure this command only after you have specified a PTP profile, PTP mode, and PTP domain for the device.
You can enable PTP on only one port if the clock node type of the device is OC.
As a best practice, enable PTP on an interface after you complete PTP configuration on the interface.
To enable PTP on a Layer 2 Ethernet interface, make sure the VLAN interface for the VLAN to which the Layer 2 interface belongs is not associated with any VPN instance (the ip binding command not configured on the VLAN interface).
To enable PTP on a Layer 3 Ethernet interface that has been assigned to a VPN instance, you must specify this VPN instance in the ptp source ip-address vpn-instance vpn-instance-name command if PTP messages are to be transmitted in multicast mode over IPv4 UDP.

Parameters
master: Specifies the PTP port as a master port.
passive: Specifies the PTP port as a passive port.
slave: Specifies the PTP port as a subordinate port.
Usage guidelines
By default, the PTP port roles are automatically negotiated based on the BMC algorithm. If you use this command to change the role of one PTP port, all the other PTP ports in the PTP domain stop working. For these PTP ports to function, you must specify roles for each of them by using this command. As a best practice, enable automatic negotiation of PTP port roles based on the BMC algorithm.
You can configure this command only after you have specified a PTP profile, PTP mode, and PTP domain for the device.
You can configure only one subordinate port for a device.

Use undo ptp min-delayreq-interval to restore the default.
Syntax
ptp min-delayreq-interval interval

Predefined user roles
network-admin
Parameters
interval: Specifies an exponent, to the power of which base 2 is raised to get the interval in seconds for sending delay request messages. When the PTP profile is IEEE 1588 version 2, the value range for the interval argument is –4 to 6. When the PTP profile is SMPTE ST 2059-2, the value range for the interval argument is –5 to 4.
Usage guidelines
When a member clock receives a Sync message, it responds by sending a Delay_Req message and starts a timer defined by this command. The member clock will not send another Delay_Req message until it receives a Sync message after the timer expires.
You can configure this command only after you have specified a PTP profile, PTP mode, and PTP domain for the device.
In PTP multicast transport mode, this command takes effect only when configured on the master clock. The master clock sends the value to a member clock through PTP messages to control the interval for the member clock to send Delay_Req messages. To view the interval, execute the display ptp interface command on the member clock.
In PTP unicast transport mode, this command takes effect when configured on member clocks. It does not take effect when configured on the master clock.
When the PTP profile is SMPTE ST 2059-2, set the interval argument to a value in the range of ptp syn-interval interval to ptp syn-interval interval plus 5 as a best practice.

Parameters
utc-offset: Sets the cumulative offset between UTC and TAI, in seconds. The value range for the utc-offset argument is 0 to 999.

An offset exists between UTC and TAI. The device displays the UTC time. However, PTP uses TAI for time synchronization. For the device to synchronize correct time to other clock nodes in the PTP domain when its local clock is selected as the GM, configure this command to correct the offset between UTC and TAI.
