F5 oneconnect profile with node running nginx

Hi All,

 

Is there any known bugs or issues when configuring F5 LTM vip with "oneconnect profile" and end nodes (in pool) running nginx application ? our network topology:

 

End user <---> | F5 ltm 11.2 with one connect profile(automap) | <-------> F5 ltm 11.5.1(automap) <-------> |---> srv2(with nginx)

 

We have every day some members in the pool are flapping on the ltm 11.5.1 : status donw and status up !

 

regards,

 

L;T

    Oneconnect won't cause your pool members to flap. The most usual explanation for flapping pool members is instability in the network between the BigIP and the pool members. There are a variety of other things that can cause this behavior, but one connect is not one of them.

     

    The BigIP will monitor from the nonfloating self IP to the pool members, and both the active and standby will send monitor traffic. If you cannot determine why your monitors are flapping, support can help you nail this down.
