must be an integer from 1 through 10080.
Usage
Use this command to configure how long to hold on to CDRs that are possibly duplicates while waiting for
the primary CGF to come back up. If the GGSN/P-GW (SAEGW) determines that the primary CGF is down,
CDRs that were sent to the primary CGF but not acknowledged are sent by the GSN to the secondary CGF as
“possibly duplicates”. When the primary CGF comes back up, the GSN uses GTPP to determine whether the
possibly duplicate CDRs were received by the primary CGF. Then the secondary CGF is told whether to
release or cancel those CDRs. This command configures how long the system should wait for the primary
CGF to come back up. As soon as the configured time expires, the secondary CGF is told to release all of the
possibly duplicate CDRs.
