PurposeCommand or Action
Displays the status of the PTP port.(Optional) switch(config-if) # show ptp port
interface interface slot/port
Step 9
Saves the change persistently through reboots
and restarts by copying the running
configuration to the startup configuration.
(Optional) switch(config-if)# copy

Step 10
Example
This example shows how to configure PTP on an interface and configure the intervals for the announce,
delay-request, and synchronization messages:
switch# configure terminal
switch(config)# interface ethernet 2/1
switch(config-if)# ptp
switch(config-if)# ptp announce interval 3
switch(config-if)# ptp announce timeout 2
switch(config-if)# ptp delay-request minimum interval 4
switch(config-if)# ptp sync interval -1
switch(config-if)# show ptp brief

Configuring Multiple PTP Domains
You can configure multiple PTP clocking domains on a single network. Each domain has a priority value
associated with it. The default value is 255.
