Configuring PTP on an Interface
After you globally enable PTP, it is not enabled on all supported interfaces by default. You must enable PTP
interfaces individually.
Before You Begin
Make sure that you have globally enabled PTP on the switch and configured the source IP address for PTP
communication.

Configuring PTP on an Interface
Purpose
Enters global configuration mode.
Specifies the interface on which you are enabling PTP
and enters interface configuration mode.
Enables or disables PTP on an interface.
(Optional)
Configures the interval between PTP announce messages
on an interface or the number of PTP intervals before a
timeout occurs on an interface.
The range for the PTP announcement interval is from 0
to 4 seconds, and the range for the interval timeout is
from 2 to 10.
(Optional)
Configures the minimum interval allowed between PTP
delay-request messages when the port is in the master
state.
The range is from log(-6) to log(1) seconds. Where,
log(-2) = 2 frames per second.
(Optional)
Configures the interval between PTP synchronization
messages on an interface.
(Optional)
Specifies the VLAN for the interface where PTP is being
enabled. You can only enable PTP on one VLAN on an
interface.
The range is from 1 to 4094.
