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 Unicast negotiation configures the Cisco MWR 2941 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 The no-negotiation parameter 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.
