Based on the table above, the recommended guidelines are as follows:
If you are going to use timeout idle settings for subscribers, it is recommended that you configure the timeout
idle parameter in the source context default subscriber to a value that is less than or equal to the lowest timeout
idle for any subscriber.
idle for any subscriber.
If you are going to use timeout absolute settings for subscribers, it is recommended that you configure the
timeout absolute in the source context default subscriber to a value that is less than or equal to the lowest
timeout idle for any subscriber.
timeout idle for any subscriber.
Failure to follow these recommendations could result in lifetime too long failures when the FA processes the subscriber
profileAPN template and finds an idle timeout that is less than the proposed MIP lifetime in the mobile RRQ.
