I have one question.
It is possible to configure Dual-Active Detection fast-hello on Port-channel?
If yes, what is the maximum authorize link?
Solved! Go to Solution.
It really doesn't matter how many fast-hello links you have when the sup fails in one chassis. For example, as soon as the sup fails in chassis-1 all traffic will be forward by the chassis-2. So, when sup fails, the whole chassis is dead.
