Step 11 Wait for 5 minutes and run the client.
J.2.4 NE Connection State Is Listed as Unavailable
If the connection state of an NE is listed as Unavailable in the Domain Explorer window, a connectivity
or configuration problem exists. Wait 5 to 10 minutes after adding the NE to the CTM domain; then,
complete the following steps:
Step 1 To see the NE IP address, select the NE in the Domain Explorer window. The Address tab of the Network
Element Properties pane lists the IP address of the selected NE.
Step 2 From the CTM server, enter the following command to verify connectivity between the CTM server and
the NE:
ping <IP_address>
Step 3 If the ping fails, a physical or configuration problem exists in the data communications network (DCN).
a. If connectivity existed earlier:
If there were no configuration changes made to any routers in the DCN or to the CTM server,
the problem is a physical problem.
If the configuration was changed, the change might have introduced problems. Verify the
changed configuration.
b. If connectivity was never established:
Verify that there are no problems on the physical level.
Verify the DCN configuration.
Step 4 If the ping succeeds, verify that the NE software version is listed in the Supported NE Table. See
4.3.7 Adding a New NE Software Version to the CTM Domain, page 4-37.
Step 5 For ONS 15501, ONS 15530, and ONS 15540 NEs, SNMP read and write community strings must be
set up properly on each NE. The running configuration on each NE should contain entries similar to the
following example:
snmp-server community public RO
snmp-server community private RW
The community strings configured on the server should match the strings configured on the NE. For
information on configuring community strings in CTM for ONS 15501, ONS 15530, and ONS 15540
NEs, see 3.5.1.4 Prerequisites for Adding ONS 15501, ONS 15530, and ONS 15540 NEs, page 3-10.
