Cisco Cisco Packet Data Gateway (PDG)

 

  For the MME to report these TAI level statistics, you must first issue the MME Service 

Configuration Mode command: 

. Only those MME Services which are 

configured accordingly will provide TAI based statistics.  

  Changing this collection mode will restart the MME service and will clear all statistics at the MME 

service and eNodeB level.
