Description
Cold Start Attempt Aborted Flag — protocol related event: ‘set coldstart abort indicator in CHI’
This flag is set when the controller has aborted a cold start attempt.
0 No such event
1 Cold start attempt aborted
Leading Cold Start Path — This status bit is set when the controller has reached the POC:normal active state
via the leading cold start path. This indicates that this node has started the network
0 No such event
1 POC:normal active reached from POC:startup state via leading cold start path
