Disabling Transparent Clock Mode for PTP

The PTP transparent clock mode can be disabled globally or on specified interfaces.
The following task shows you how to disable the transparent clock mode on a specified interface.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter interface configuration mode. 
    device(config)# interface ethernet 1/1/5
  3. Disable PTP on the Ethernet interface 1/1/5 using the no form of the command. 
    device(config-if-e25000-1/1/5)# no ptp-clock transparent pkt-type ethernet option e2e step-type onestep
PTP Feature Disabled on port 1/1/5
device(config)# show ptp-clock
Clock             : Transparent
Clock ID          : 00e0.5200.0100
PTP Enabled Ports : e 1/1/1 to 1/1/4 e 1/1/6 to 1/1/48 e 1/2/1 e 1/2/2
                    e 1/2/3 e 1/2/4 e 1/2/5 e 1/2/6 e 1/2/7 e 1/2/8
