3. Configure the interval for
sending Sync messages.

By default:
• The interval is 2

seconds if the
PTP standard is IEEE 1588
Version 2.
• The interval is 2

3. Configure the minimum
interval for sending
Delay_Req messages.
ptp min-delayreq-interval value
The default is 1s (2

s).
When receiving a Sync or
Follow_Up message, an interface
can send Delay_Req messages
only when the minimum interval is
reached.
Configuring the MAC address for non-pdelay messages
Pdelay messages include Pdelay_Req, Pdelay_Resp, and Pdelay_Resp_Follow_Up messages. The
destination MAC address of Pdelay messages is 0180-C200-000E by default, which cannot be modified.
The destination MAC address of non-Pdelay messages is either 0180-C200-000E or 011B-1900-0000.
If ports on the same link forward PTP packets of the same type to different destination MAC addresses,
they do not receive the packets from each other. You need to configure the same destination MAC
address for the ports.
