CSCup54025 - S1 and SGs associations not equally distributed across
mmemgr tasks
Feature Changes
Delay in Processing Traffic After Restart
Previous Behavior: After an MME reboot or an SGs service configuration change, the S1 and SGs associations were
not equally distributed across available MME Manager processes. On startup, the MME was starting to allocate traffic
to individual MME Manager processes before all MME Manager processes were activated.

to individual MME Manager processes before all MME Manager processes were activated.
New Behavior: The MME now waits for all MME Manager processes to become available before processing traffic.
Performance Indicator Changes
show session subsystem facility mmedemux verbose
The following counter has been added to the output of the
show session subsystem facility mmedemux
verbose
command.
This counter tracks the number of incoming packets dropped by the MME Demux subsystem (at S1 interface, coming
from eNodeB) while waiting for all MME Managers to be activated (status = UP). The MME waits to start processing
traffic only after the expected number of MME Managers are UP after an MME restart.
