Table 20-21 PTP Service Properties
Field Description
PTP Mode Mode of PTP operation:
• Boundary—Boundary clock mode.
• E2E Transparent—End-to-end transparent clock mode.
• Ordinary—Ordinary clock mode.
• P2P Transparent—Peer-to-peer transparent clock mode.
• Unknown—The clock mode is unknown.
Note Cisco MWR-2941 routers support Ordinary mode only.
PTP Clock ID Clock identifier derived from the device interface.
PTP Domain Number of the domain used for PTP traffic. A single network can contain
multiple separate domains.
Priority 1 First value checked for clock selection. The clock with the lowest priority takes
precedence.
Priority 2 If two or more clocks have the same value in the Priority 1 field, the value in this
field is used for clock selection.
Port State Clock state according to the PTP engine:
• Freerun—The slave clock is not locked to a master clock.
• Holdover—The slave device is locked to a master device, but communication
with the master is lost or the timestamps in the PTP packet are incorrect.
• Acquiring—The slave device is receiving packets from a master and is trying
to acquire a clock.
• Freq locked—The slave device is locked to the master device with respect to
frequency, but is not aligned with respect to phase.
• Phase aligned—The slave device is locked to the master device with respect
to both frequency and phase.
PTP Interface List Table
Interface Name Interface identifier.
PTP Version Version of PTP used. The default value is 2, indicating PTPv2.

Port Role PTP role of the clock: Master or Slave.
PTP Slave Mode For an interface defined as a slave device, the mode used for PTP clocking:
• Not Set—The slave mode is not used.
• Multicast—The interface uses multicast mode for PTP clocking.
• Unicast—The interface uses unicast mode for PTP clocking.
• Unicast with Negotiation—The interface uses unicast mode with negotiation
for PTP clocking.
