Enabling Generalized Precision Time Protocol on an Interface To enable gPTP on an interface, complete the following task: Procedure Configuring the Values of Precision Time Protocol Clocks Follow these steps to configure the values of PTP clock priority1 and priority2: Procedure Configuring Audio Video Bridging Enabling Generalized Precision Time Protocol on an Interface Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device# configure terminal Enters the global configuration mode. Step 3 interface interface-id Example:
Device(config)# interface te1/1/1 Defines the interface to be configured as a trunk, and enters interface configuration mode. The interface that you specify can be part of an EtherChannel. Step 4 ptp enable Example: Device(config-if)# ptp enable Enables gPTP on all the interfaces. Use the no form of this command to disable gPTP on an interface Step 5 end Example: Device(config-if)# end Returns to privileged EXEC mode. Command or Action Purpose Step 1 enable Example: Device> enable Enables privileged EXEC mode. Enter your password, if prompted. Step 2 configure terminal Example: Device# configure terminal Enters global configuration mode. Step 3 ptp priority1 value Example:
Sets the value of PTP clock priority1. The range is from 0 to 255. The default value is 128. Note Configuring Audio Video Bridging 10
