Appendix B Cisco MWR 2941 Router Command Reference
ptp delay-req unicast
ptp delay-req unicast
Configures the Cisco MWR 2941 to send unicast PTP delay request messages while in multicast mode.
This command helps reduce unnecessary PTP delay request traffic.
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.

Command History
Usage Guidelines If the Cisco MWR 2941 is in PTP multicast slave mode using unicast delay request messages and is
connected to another Cisco MWR 2941 as a master clock, ensure that the master clock is also configured
to use unicast delay request messages.
Examples The following example shows how to configure PTP delay-req unicast:
Router# config t
Router(config)# interface vlan 10
Router(config-if)# ptp delay-req unicast negotiation
Router(config-if)# exit
Router(config)# exit
unicast Configures the Cisco MWR 2941 to send unicast PTP delay request messages
while in multicast mode.
negotiation Specifies that the Cisco MWR 2941 use unicast negotiation to discover the
PTP master clock by sending delay request messages to all devices specified
as PTP clock sources in the local router configuration.
no-negotiation Disables unicast negotiation on the Cisco MWR 2941 in slave mode. If you
disable unicast negotiation, ensure that the PTP master clock is configured
with the slave IP address. The slave Cisco MWR 2941 obtains the PTP master
IP address from Announce messages received from the PTP master clock. The
Cisco MWR 2941 then sends delay request messages to the PTP master clock.
