Dear all,
I please have the following short question:
What is the flapping rate (down/up in what time interval) of an interface on a Nexus 7k to trigger the "errdisable link-flap" feature?
I have searched a lot of documents and on the internet but I have not found any explicit information on it for Nexus.
I have just found the general information that it is triggered on some Cisco devices when an interface goes up and down more than 5 times within 10 seconds.
Thank you for your feedback.
Cheers
Karl

- Do you have show errdisable flap-values as an available command on the N7K ?

- Check wether you can influence the behavior of flap detection with :
config # errdisable flap-setting cause link-flap max-flaps 3 time 20
