Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
The following examples demonstrate how to use these commands to configure each of the PTP modes.
Use the appropriate section based on the PTP mode that you want to configure on the Cisco MWR 2941.
• PTP multicast master mode—Sets the Cisco MWR 2941 to act as the master PTP clock. Multicast
specifies that the router sends PTP messages to all the slaves listening on the PTP multicast group.
Note PTP master mode is intended for trial use only and is not for use in a production network.
Router(config)# interface Vlan10
Router(config-if)# ip address 192.168.52.38 255.255.255.0
Router(config-if)# ip igmp join-group 224.0.1.129
Router(config-if)# ptp announce interval 0
Router(config-if)# ptp sync interval -6
Router(config-if)# ptp delay-req interval -4
Router(config-if)# ptp master multicast
Router(config-if)# ptp enable
• PTP multicast slave mode—Sets the Cisco MWR 2941 to receive clocking from a PTP master
device in multicast mode.
Router(config)# interface Vlan10
Router(config-if)# ip address 192.168.52.38 255.255.255.0
Router(config-if)# ip igmp join-group 224.0.1.129
Router(config-if)# ptp announce interval 0
Router(config-if)# ptp sync interval -6
Router(config-if)# ptp delay-req interval -4
Router(config-if)# ptp slave multicast
Router(config-if)# ptp enable
• PTP multicast slave mode (with hybrid clocking)—Sets the Cisco MWR 2941 to receive phase from
a PTP master device in multicast mode while using clock frequency obtained from the synchronous
Ethernet port.
Router(config)# interface Vlan10
Router(config-if)# ip address 192.168.52.38 255.255.255.0
Router(config-if)# ip igmp join-group 224.0.1.129
Router(config-if)# ptp announce interval 0
Router(config-if)# ptp sync interval -6
Router(config-if)# ptp delay-req interval -4
Router(config-if)# ptp slave multicast hybrid
Router(config-if)# ptp enable
Note You can use the ptp delay-req unicast command to set the Cisco MWR 2941 to send unicast PTP
Delay_Req messages while in multicast mode in order to eliminate unnecessary multicast traffic. For
more information about this command, see Appendix B, “Cisco MWR 2941 Router Command
Reference.”
ptp slave Sets an interface to slave clock mode for PTP clocking.
ptp sync Specifies the interval that the router uses to send PTP synchronization
messages.
