Chapter 12 IEEE 1588v2 PTP Support
Configuring IEEE 1588v2 PTP
Examples
The following example shows how to configure an ordinary clock as PTP slave:
Router# configure terminal
Router(config)# ptp clock ordinary domain 0
Router(config-ptp-clk)# clock-port SLAVE master
Router(config-ptp-port)# transport ipv4 unicast interface Loopback22 negotiation
Router(config-ptp-port)# clock source 10.10.10.10
Router(config-ptp-port)# end
Configuring a Boundary Clock
You can configure the PTP master and PTP slave in a boundary clock topology as shown in
in the same way that you configure a master and slave in ordinary clock mode. This section describes
how to configure a Cisco ASR 1002-X Router in boundary clock mode.
how to configure a Cisco ASR 1002-X Router in boundary clock mode.
Note
Currently, boundary clock supports only unicast negotiation mode.

PTP Boundary Clock Scenario
SUMMARY STEPS
1.
configure terminal
2.
ptp clock boundary
domain domain_number
3.
clock-port name slave
4.
transport ipv4 unicast interface {GigabitEthernet | Loopback} interface-number {negotiation}
5.
clock source ip-address
Step 5
clock source
ip-address
Example:
Router(config-ptp-port)# clock source
10.10.10.10
Specifies the source IP address of a PTP master clock.
Note
You can specify only 1 master clock IP address.
Priority-based clock source selection is not
supported.
