Configuring IP addressing This section provides information about configuring IP addressing. Configuring IBM Spectrum Control with multiple IP addressesIf the system where IBM Spectrum® Control is to be installed has multiple IP addresses, then a configuration value must be set manually as a post-installation task by using the tpctool setdscfg command. The value to be set is for the local IP address, which must be used for subscription for CIM Indications for CIM agents. Changing the HOSTS fileWhen you install IBM Spectrum® Control on your Windows™ operating systems, you must follow these steps to avoid addressing problems with the systems you want to manage. These problems are caused by the address resolution protocol that returns the host short name rather than the fully qualified host name. You can avoid this by modifying the entries in the corresponding host tables on the DNS server and on the local computer system. The fully qualified host name must be listed before the short name in each entry that is associated with systems managed by IBM Spectrum® Control. Parent topic: Configuring
