Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR
ptp slave
ptp slave
Sets an interface to slave clock mode for PTP clocking. To enable ordinary slave clock mode, use the
ptp slave command in interface configuration mode. To disable this feature, use the feature, use the no
form of this command.
Note The Cisco MWR 2941 only supports multicast routing for PTP redundancy. For more information, see
the Cisco MWR 2941-DC Mobile Wireless Edge Router Software Configuration Guide.
ptp slave {multicast | unicast [negotiation]} [hybrid]
no ptp slave {multicast | unicast [negotiation]} [hybrid]
Syntax Description
Defaults There is no default setting.
Command Modes Interface configuration
Command History
Usage Guidelines You must configure the IP address of the remote timing device before enabling PTP.
To configure hybrid mode, ensure that you have selected a synchronous Ethernet timing source using the
network-clock-select command. You cannot configure hybrid mode if network-clock-select is
configured for packet timing.
Examples The following example shows how to enable ptp slave multicast mode:
Router# config t
Router# interface Vlan10
Router(config-if)# ptp slave multicast
Router(config-if)# exit
multicast Sets the interface to use multicast mode for PTP clocking.
unicast Sets the interface to use unicast mode for PTP clocking.
negotiation Sets the interface to negotiate unicast mode for PTP clocking.
hybrid Enables hybrid clocking mode, in which the Cisco MWR 2941 uses clock
frequency obtained from the synchronous Ethernet port while using phase
(ToD or 1PPS) obtained using PTP. You must enable synchronous Ethernet
network clocking to configure hybrid mode.
Release Modification

12.2(33)MRA Added parameter to enable hybrid clocking mode.
