Configuring Clocking and Timing
The Cisco MWR 2941 supports the following network clocking types:
• Precision Time Protocol (PTP)—Clocking and clock recovery based on the IEEE 1588-2008
standard; allows the Cisco MWR 2941 router to receive clocking from another PTP-enabled device
or provide clocking to a PTP-enabled device. To configure PTP clocking, see the “Configuring PTP
Clocking” section on page 4-39. If you want to enable PTP redundancy, see the “Configuring IP
Multicast” section on page 4-64.
• Pseudowire-based clocking—Allows the Cisco MWR 2941 router to use clocking using a
pseudowire or virtual pseudowire interface. Pseudowire-based clocking supports adaptive clock
recovery, which allows the Cisco MWR 2941 to recover clocking from the headers of a packet
stream. To configure pseudowire-based clocking, see the “Configuring Pseudowire-based Clocking
with Adaptive Clock Recovery” section on page 4-45
• Synchronous Ethernet—Allows the network to transport frequency and time information over
Ethernet. To configure synchronous Ethernet, see the “Configuring Synchronous Ethernet” section
on page 4-47.
• Verifying Clock Settings—To verify a clocking configuration, see the “Verifying Clock-related
Settings” section on page 4-49.
Note The Cisco MWR 2941 does not support the use of PTP and PWE-based clocking at the same time.
Configuring PTP Clocking
This section describes how to configure PTP-based clocking on the Cisco MWR 2941. For more
information about the PTP commands, see, Appendix B, “Cisco MWR 2941 Router Command
Reference.”
Note The settings shown in this section are an example only; you must determine the appropriate PTP settings
based upon your network clocking design.
Note The configuration sections describing the 1PPS and 10Mhz timing ports only apply to the Cisco MWR
2941-DC-A; the Cisco MWR-DC router does not have these timing ports.
