Server Problems
C.1.3 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 Cisco MGM 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 sheet lists the IP address of the selected NE.
Step 2 From the Cisco MGM server, enter the following command to verify connectivity between the
Cisco MGM server and the NE:
ping IP_address
Step 3 If the ping fails, a physical or configuration problem exists in the communication between an NE and
Cisco MGM.
Step 4 If the ping succeeds, verify that the NE software version is listed in the Supported NE Table.
Step 5 SNMP read and write community strings must be set up properly on each NE. To view the community
string, enter:
dspsnmp
The community strings configured on the server should match the strings configured on the NE. For
information on configuring community strings in Cisco MGM.
C.1.4 Launching Tables Results in Database Errors
If the Oracle database or Oracle listener that Cisco MGM is using is down, launching tables will generate
database errors. To troubleshoot table launching errors:
Step 1 Log in as the Oracle user and enter the following command:
sqlplus ctmanager/ctm123!
If login is successful, an SQL> prompt appears, which indicates that the Oracle database has been
installed and the database server is up and running. If login fails, either the Oracle database has not been
installed or the database server is not running.
Step 2 To start the Oracle database, log into the Solaris workstation as the Oracle software owner user.
Step 3 Enter the following command at the shell prompt to start the Oracle database:
dbstart
Step 4 Enter the following command at the shell prompt to start the Oracle listener:
lsnrctl start
If there are still problems with starting the Oracle database or the Oracle listener, refer to the Oracle
documentation or contact Oracle support.
