Dec 25, 2016
- Cisco ASR 5000 Series
Known Affected Releases
Symptom: Dedicated bearer creation is not triggered from PGW on installing same rule which was removed earlier after MBR/DBR collision happens on that subscriebr session. Conditions: PGW initiates Delete Bearer Request for dedicated bearer EBI and there is on wire collision of it with MBReq coming from SGW/MME which does not include EBI for which DBReq was initiated. This collision handling at PGW leaves the rule related to that EBI in anomalous state at PGW. Further Rule installation succeeds. But after that point removal of the rule and install of the same rule does not work.
