Configuring Clocking and Timing
• 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 device; 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
• PTP unicast slave mode (with hybrid clocking)—Sets the Cisco MWR 2941 to receive phase (ToD
or 1PPS) from a single PTP master device while using clock frequency obtained from the
synchronous Ethernet port.
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 hybrid
Router(config-if)# ptp clock-source 192.168.52.10
Router(config-if)# ptp enable
• PTP unicast slave mode (with hot standby master clock)—Sets the Cisco MWR 2941 to receive
clocking from a single PTP master device and enables a standby master clock. When you enable a
standby master clock, the Cisco MWR 2941 selects the best clock source between two PTP master
clocks and switches dynamically between them if the clock quality of the standby clock is greater
than that of the current master clock. If you define a standby master clock, both clock sources must
be in the same VLAN. Setting a standby master clock in unicast mode is optional.
