Cisco Bug: CSCuq97455 - stp_io crash seen after ifmgr crash during edge link flap
Jul 30, 2018
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: stp_io process abnormally restarts following an ifmgr abnormal restart. The traceback matches that in the DDTS. In some cases (e.g. high scale, RP switchover), the process restart may not be quick enough to prevent protocol timeouts so there is some risk of a short period of network loops and/or traffic loss. Conditions: This issue is only seen when an STP interface registration attempt happens at the same time as ifmgr is unavailable (e.g. due to ifmgr restarting).
