I have a CCR1036-8G-2S+EM with 10GB link with a CRS317 and the sfp’s interfaces are flapping!
The time between those flappings is completely random.
We took some actions to try to fix the situation:
Changed CRS317 for a CRS305 >> still flapping.
Changed gbics and cords >> still flapping
Disabled auto negotiation in both boards >> still flapping
I noticied that only on CRS317 and CRS305 is telling us about interface is going down, when the flap occurs in the log. The CCR1036 don’t pop up not even a warning, except for OSPF going down.
Then we decide to make a bound (LACP) between the CCR1036-8G-2S+EM and the CRS317, because we think that that are much harder two interfaces flap at once,right? Wrong, both sfp interfaces flapped at same time. So, problem not solved.
The CRS317 is a bridge dumb config with bounding:

There is any solution? Thank you.
