IP Identification (ID) Field

By default, non-fragmented UDP packets generated by media interfaces have the ID field set to 0. You can configure the Oracle® Enterprise Session Border Controller to populate this field with an incrementing value by adding the increment-ip-id option in the media manager. Every non-fragmented packet sent will have its ID increased by one from the previous packet sent.

Using a packet trace application, egress packets from the Oracle® Enterprise Session Border Controller will have an ID field that appears to be incrementing. Enabling the ID field can help distinguish a retransmitted non-fragmented application layer packet from a packet retransmitted by the network layer in monitoring or lab situations.
