Chapter 16 Configuring Clocking and Timing

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 Configuring PTP

Clocking. If you want to enable PTP redundancy, you must also complete the steps in the

Configuring PTP Redundancy section.

• 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 Configuring Pseudowire-Based Clocking with

Adaptive Clock Recovery.

• Synchronous Ethernet—Allows the network to transport frequency and time information over

Ethernet. To configure synchronous Ethernet, see Configuring Synchronous Ethernet.

• Verifying Clock Settings—To verify a clocking configuration, see Verifying Clock-Related Settings.

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 the Cisco MWR 2941 Mobile Wireless Edge Router IOS

Command Reference, Release 15.0(1)MR.

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.
