Configuring Back-off and Jitter Timers in DNN Profile
To define values for the back-off and jitter timers in DNN profile, use the following sample configuration:
config
profile dnn dnn_profile_name
timeout backoff backoff_timer_value
timeout jitter jitter_timer_value
end
NOTES:
-
timeout backoff backoff_timer_value : Specify the back-off timer value, in seconds. backoff_timer_value must be an integer in the range of 0-576000.
The back-off timer is the maximum allowed duration used during IP exhaustion and N4 path failure cases.
-
timeout jitter jitter_timer_value : Specify a jitter value to introduce randomness in the back-off timer value. jitter_timer_value must be an integer in the range of 0-1000.
The jitter allows spreading the different backoff timers to the UE devices so that they all wait at different times before the next reconnection attempt.
This configuration helps to prevent a session storm after the back-off timer expiry.
The following is an example configuration used during N4 path failure scenarios.
config
profile dnn test
timeout backoff 200 jitter 50
