3.Save the file.

4.Restart the CIM extension for your changes to take effect.

NOTE: The CIM extension looks for parameters in the cim.extension.parameters file whenever it starts, such as when it is started manually or when the host is rebooted.

5.The management server assumes the CIM extension is running on port 4673. If you change the port number, you must make the management server aware of the new port number.

Enter the port number on the System Protocol Settings page (Options > Protocol Settings > System Protocol Settings) under the WBEM section. See the SIM documentation for more information.

Configuring UNIX CIM Extensions to Run Behind Firewalls

In some instances you will need to discover a host behind a firewall. Use the following table as a guideline. Assume the management server wants to discover HostA, which has three network interface cards on three separate networks with three separate IPs: 10.250.250.10, 172.31.250.10, and 192.168.250.10. In the following table different configurations are presented:

•The “Manual Start Parameters for CIM Extensions” column provides what you would enter to start the CIM extension manually on the host. See the Installation Guide for more information on how to start a CIM extension manually.

•The “If Mentioned in cim.extension.parameters” column provides information on how you would modify the cim.extension.parameters file. See ”Permanently Changing the Port a CIM Extension Uses (UNIX Only)” on page 388.
