Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
• PTP unicast master mode—Sets the Cisco MWR 2941 to act as the master PTP clock. Unicast
specifies that the router sends PTP messages to a single slave host.
Router(config)# interface Vlan2
Router(config-if)# ip address 192.168.52.38 255.255.255.0
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 unicast
Router(config-if)# ptp clock-destination 192.168.52.201
Router(config-if)# ptp enable
• PTP unicast master mode (with negotiation enabled)—Sets the Cisco MWR 2941 to send clocking
to a single PTP slave device; the router allows the slave devices to negotiate their master clock
device. When in the router is in PTP unicast master mode, you can specify up to 128 PTP clock
destination devices.
Note If you set the router to PTP master unicast mode with negotiation, you do not specify PTP clock
destinations because the router negotiates to determine the IP addresses of the PTP slave devices.
Note We recommend that you determine the number of destination devices to assign to a master clock based
on traffic rates and available bandwidth.
Router(config)# interface Vlan2
Router(config-if)# ip address 192.168.52.38 255.255.255.0
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 unicast negotiation
Router(config-if)# ptp enable
• PTP unicast slave mode—Sets the Cisco MWR 2941 to receive clocking from a single PTP master
device.
Router(config)# interface Vlan2
Router(config-if)# ip address 192.168.52.38 255.255.255.0
Router(config-if)# ptp announce interval 3
Router(config-if)# ptp announce timeout 2
Router(config-if)# ptp sync interval -6
Router(config-if)# ptp delay-req interval -4
Router(config-if)# ptp slave unicast
Router(config-if)# ptp clock-source 192.168.52.10
Router(config-if)# ptp enable
• PTP unicast slave mode (with negotiation enabled)—Sets the Cisco MWR 2941 to receive clocking
from a PTP master devices; the router negotiates between up to 128 PTP master devices.
Router(config)# interface Vlan2
Router(config-if)# ip address 192.168.52.38 255.255.255.0
Router(config-if)# ptp announce interval 3
Router(config-if)# ptp announce timeout 2
Router(config-if)# ptp sync interval -6
Router(config-if)# ptp delay-req interval -4
Router(config-if)# ptp slave unicast negotiation
Router(config-if)# ptp clock-source 192.168.52.10
Router(config-if)# ptp enable
