Configuring Multiple PTP Domains

Step 9
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
