15.2(4)S 15.3(3)S 15.4(1)S 15.4(2)S

Description (partial)

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.
