Center.
Step 2 Click the Elements tab to display the Configuration Window for Elements.
Step 3 Click the Clocking tab to display Clocking Configuration window.

Step 6 Choose one of the following clock source options from the Priority drop-down arrow:
• primary— Configures an available network clock source to be the primary manual clock source.
• secondary—Configures an available network clock source to be the secondary manual clock source.
• default—Configures an available network clock source to be the default manual clock source.

3.12 How Do I Test Connectivity for Optical and Routing
Devices?
The following sections describe how to test server connectivity to an NE. Table 3-21 explains the
difference between pinging an NE and testing NE connectivity.
Table 3-21 Testing NE Connectivity
Method Description
Ping NE Pinging the NE uses the standard UNIX ping command to verify IP connectivity between the CTM
server and an NE. If successful, the ping results include the NE’s IP address, round-trip time, and packet
loss statistics. A response of “Request timed out” means there was no response to the ping attempt. If
the ping is unsuccessful, verify that the NE’s IP address and SNMP settings are configured correctly.
Test NE
connectivity
The Test NE Connectivity operation uses the appropriate management protocol (SNMP, TL1, or
CORBA) to run the ping command to verify the server’s IP connectivity to an NE. If the ping is
successful, the Test NE Connectivity operation verifies that the management protocol is configured
correctly. The results show whether the connection state of the NE is Available or Unavailable. If
Available, the connection state of an NE is updated to Available in the CTM database. If the connection
state of an NE is listed as Unavailable, a connectivity or configuration problem exists. Complete the steps
in J.2.4 NE Connection State Is Listed as Unavailable, page J-5 to resolve the problem and retest NE
connectivity.
