Description (partial)


Under stress condition, due to getbuffer failures or inband interface throttling, inband may drop BPDUs. This affects the reliability of control protocols.


To minimize the impact from control plane instability, a notification mechanism is needed to inform inband clents before packet drop happens and after regular operation resumes on a particular port. This will benefit fast UDLd and also can benefit other upper layer protocols.
