Hi,
I checked and it looks no easy possibility for detecting link loss at
controller AvD as it gets AvND down and Avnd UP in the tipc flicker. This is
the same even when payload goes down and rejoins. Only time difference is the
differentiator between these two scenario.
Hans: Can you please check any other possibility at Amfd to detect tipc flicker?
Thanks

and Payload flickers [#600]
Hi Nagu,
What is the discrimination point that the link flap has occurred with only one
PLD? The chances of getting link flap with one Payload is less when compared
wiht link flap with all the payloads. With my suggestion, there will be a
failover. but with the present patch if a link flap happens with the payload
nodes, all the payload nodes will go for reboot. So considering in total, i
guess we should reboot the Active controller only.
Regards
Surya
