configure
ddn-apn-profile ddn-apn_profile_name
qci value ddn falure-action pkt-drop-timer value
remove qci value
end
Notes:
This value supersedes the one configured at sgw-service-level.
When DDN failure is received, the minimum of the pkt-drop-timer of all QCIs having data is started.
qci <value> ddn ignore-ddn-timers
This command has been added to DDN APN Profile Configuration Mode so that if any DDN timer (DDN delay or
DDN failure) is started and data arrives on a bearer with QCI for which this flag is set, then S-GW will stop that timer
and send DDN again. This helps S-GW to send DDN for preferential bearers immediately on receiving new data.
