Interface identification on the Oracle Communications Session Delivery Product is based on a system-level file called MACTAB that maps interface MAC addresses to interface naming that can be applied within Oracle Communications Session Delivery Product configuration. In most cases, users retain the default mapping. The interface-mapping, show command provide access to commands that allow the user see, change and even locate each interface based on this mapping. The MACTAB file is stored in the /boot folder. The MACTAB file ensures that interface mapping is persistent, and therefore usable, by your configuration regardless of changes to the system.

The interface-mapping, show command displays the current mapping. An example of a MACTAB file that a user has configured is provided below.
