Appendix B Cisco MWR 2941 Router Command Reference

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 “Configuring Pseudowire-based Clocking with Adaptive Clock Recovery” section on page 4-45.

ptp slave {multicast | unicast [negotiation]} [hybrid]

no ptp slave {multicast | unicast [negotiation]} [hybrid]

Syntax Description

Command Default 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

Router(config)# exit

multicast Sets the interface to use multicast mode for PTP clocking.

unicast Sets the interface to use unicast mode for PTP clocking.

negotiation (Optional) Sets the interface to negotiate unicast mode for PTP clocking.

hybrid (Optional) 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

12.4(19)MR2 This command was introduced.

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