Cisco Bug: CSCul50570 - Ucode crash followed by cpp crash while scaling to 500 MLPoA bundles PTA
Apr 17, 2019
- Cisco ASR 1000 Series Aggregation Services Routers
Known Affected Releases
15.2(4)S 15.3(3)S 15.4(1)S 15.4(2)S
Symptom: A hardware interrupt causes service outage and a micro-code core will be generated. This condition puts the router in an inoperable state. This issue would affect bundle interfaces such as MLPPP and GEC aggregate mode. Conditions: While processing dynamic reconfiguration events, one of the scheduling node is left in a committed but not forward state. When a flush packet is injected in a flush queue to complete the reconfiguration process, it causes a hardware interrupt when it traverses the node that was left in a non-forwarding state.
