master unicast mode.

Command History
Usage Guidelines If the router is set to ptp master unicast, you can only configure a single destination. If the router is set
to ptp master unicast negotiation, you do not need to use this command as the router uses negotiation to
determine the IP address of PTP slave devices.
Examples The following example shows how to configure a PTP announcement:
Router(config-ptp-clk)# clock-port MASTER Master
Router(config-ptp-port)# transport ipv4 unicast interface loopback
Router(config-ptp-port)#clock destination 8.8.8.2
Router(config-if)# exit
Router(config)# exit
Related Commands
clock-ip-address The IP address of the clock destination.
Release Modification

Command Description
ptp enable Enables PTP mode on an interface.
ptp master Sets an interface in master clock mode for PTP clocking
ptp mode Specifies the PTP mode.
