The following example shows how to configure PTP globally on the device, specify the source IP address for
PTP communications, and configure a preference level for the clock:
switch# configure terminal
switch(config)# feature ptp
switch(config)# ptp source 10.10.10.1
switch(config)# ptp priority1 1
switch(config)# ptp priority2 1
switch(config)# show ptp brief
PTP port status

switch(config) # [no] ptp

running-config startup-config
Purpose
(Optional)
Configures the domain number to use for this clock. PTP
domains allow you to use multiple independent PTP clocking
subdomains on a single network.
The range for the number is from 0 to 128.
(Optional)
Configures the priority1 value to use when advertising this
clock. This value overrides the default criteria (clock quality,
clock class, and so on) for the best master clock selection.
Lower values take precedence.
The range for the value is from 0 to 255.
(Optional)
Configures the priority2 value to use when advertising this
clock. This value is used to decide between two devices that
are otherwise equally matched in the default criteria. For
example, you can use the priority2 value to give a specific
switch priority over other identical switches.
The range for the value is from 0 to 255.
(Optional)
Displays the PTP status.
(Optional)
Displays the properties of the local clock.
(Optional)
Saves the change persistently through reboots and restarts by
copying the running configuration to the startup configuration.
