Parameters

time-offset-value: Specifies the time-offset threshold between the external reference clock and the PTP clock, in the range of 200 to 1000, in nanoseconds.

Usage guidelines

Parameters

multiple-value: Sets the timeout multiplier for the announce message receiving interval, in the range of 2 to 10.

Usage guidelines

A master node periodically sends announce messages to the member nodes. If a member node does not receive any announce message from the master node within multiple-value times the announce message sending interval configured on the master node, it determines that the master node is invalid.

This command is available only after you specify a PTP profile and a PTP clock node type.

Parameters

mac-address: Specifies the destination MAC address (any unicast MAC address) for PTP unicast messages or specifies the destination MAC address (0180-C200-000E or 011B-1900-0000) for non-peer delay multicast messages.

Usage guidelines

This command is available only after you specify a PTP profile and specify a PTP clock node type.

This command takes effect only when PTP messages are encapsulated in IEEE 802.3/Ethernet packets.

IEEE 802.3/Ethernet-encapsulated PTP messages can be sent through multicast (default) or unicast.

· In multicast mode, the destination MAC address is 0180-C200-000E or 011B-1900-0000 for non-Pdelay messages and 0180-C200-000E for Pdelay messages. Non-Pdelay messages include delay_Req, delay_Resp, delay_Resp_Follow_Up, Announce, Sync, and FollowUp messages. Pdelay messages include Pdelay_Req, Pdelay_Resp, and Pdelay_Resp_Follow_Up messages.

· In unicast mode, you can configure any unicast MAC address as the destination address for PTP messages.

Examples

# Configure 0180-C200-000E as the destination MAC address for non-peer delay messages on Ten-GigabitEthernet 3/1/1.

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. The value range for the interval argument is –4 to 6.

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.

This command is available only after you specify a PTP profile and a PTP clock node type.

The configured interval takes effect only when it is set 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 value on a member clock, execute the display ptp interface command on the member clock.

Examples

# Set the minimum interval to 4 (22) seconds for sending delay request messages on Ten-GigabitEthernet 3/1/1.
