The interface-mapping Branch

The interface-mapping branch resides at the root level of the Oracle Communications Session Border Controller's ACLI. It contains a group of commands used for mapping physical interfaces on virtual machines or COTS platforms to the Oracle Communications Session Border Controller application's configuration. The system accomplishes this using physical interface MAC addresses and ACLI configuration interface naming.

Sample default Oracle Communications Session Border Controller interface mapping is presented below, using the interface-mapping, show command: 

ORACLE(interface mapping)# show

You can check or change phy-interface to MAC address configurations using the names shown under the Eth_IF column. You can identify the two types of physical interfaces that apply to the Oracle Communications Session Border Controller, by the naming conventions:

  • Management interfaces, shown above as wancom0, wancom1 and wancom2
  • Media interfaces, shown above as s0p0, s0p1, s1p0 and s1p1

It is recommended that the user configure physical interfaces using the naming in the Eth-IF column above on COTS and VM platforms. These conventions, which simply use 's' for slot and 'p' for port, are visible in the interface-mapping, show output.

The default interface mapping assignment assumes four interfaces on the VM. If deployed with less than four, the user may need to re-assign the resulting interface mapping, which they can verify using the interface-mapping, show command after system start-up. If the mapping is wrong, the interface-mapping, show command allows the user to correct it. The most likely change would be to swap the wancom1 mapping with a viable media interface.
