mac-address: Specifies the destination MAC address for non-peer delay messages, which can be 0180-C200-000E or 011B-1900-0000.

Usage guidelines

This command is available only after you specify a PTP profile and a PTP mode.

Peer delay messages include Pdelay_Req, Pdelay_Resp, and Pdelay_Resp_Follow_Up messages. By default, the destination MAC address for peer delay messages is 0180-C200-000E, which cannot be modified.

This command is available only if you specify the PTP profile as IEEE 1588 version 2.

This command is available only if PTP messages are transported over Ethernet.

Examples

# Configure the destination MAC address for non-peer delay messages as 0180-C200-000E on Ten-GigabitEthernet 1/0/1.
