Chapter 20 Monitoring MToP Services Configuring Clock
Configuring Clock
With Ethernet equipment gradually replacing SONET and SDH equipment in service-provider netwo rks,
frequency synchronization is required to provide high-quality clock synchr onization over Ethernet ports.
SyncE and PTP are two widely used clock synchronization protocol used in ethernet based networks.
Clocking configuration commands allows you to configure SyncE and PTP clock configuration on Cisco
router. SyncE and PTP clocking configuration is predominantly used in RAN Backha ul (or MToP)
network where TDM traffic carried from cell site router to central office via packet switched network.
These commands can be launched from the logical inventory by right- click ing on Clock no de. Before
executing any commands, you can preview them and view the results.
To run the these commands, the software on the network element must suppor t t he t ec hnolo gy. Before
executing any commands, you can preview them and view the results. For details on the software
versions Prime Network supports for the listed supported network elements, see Cisco Prime Network
4.0 Supported Cisco VNEs.
Note You might be prompted to enter your device access credentials while executing a command. Once you
have entered them, these credentials will be used for every subsequent execution of a command in the
same GUI client session. If you want to change the creden tial s, clic k E dit Credentials. The Edit
Credentials button will not be available for SNMP commands or if the command is scheduled for a later
time.
The table below lists the PTP and SyncE configuration commands. Additional commands may be
available for your devices. New commands are often provided in Prime Network Device Packages,
which can be downloaded from the Prime Network software download site. For more information on
how to download and install DPs and enable new commands, see the information on “Adding Additional
Device (VNE) support” in the Cisco Prime Network 4.0 Administrator Guide.
Clock Source Right-click on SONET port and
select Commands > SONET >
Configure >
Clock source of sent signal on SONET
ports:
• internal—Controller will clock its
sent data using internal clock.
• line—Controller will clock its sent
data using the clock recovered
from the line’s receive data stream.
• default—Cancels any clock source
setting.
TCA Threshold TCA threshold:
• b1-tca—Threshold for B1 BER
TCA, between 3-9 (default is 6).
• b2-tca—Threshold for B2 BER
TCA, between 3-9 (default is 6).
Bit error rate: Value from 3-9 (10 to the
negative x), or default.
