value
By default:
•
The interval is 1 (2

) second
if the PTP standard is IEEE
1588 version 2.
•
The interval is 1/8 (2

seconds if the PTP standard
is IEEE 802.1AS.

Set the minimum interval for
sending Delay_Req
messages.
ptp

value
The default is 1 (2

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.
