There is a weird issue with one of our switch 10G links. The traffic which was 1:1 bidirectional suddenly become unidirectional.
Traffic was around 3G In and out but now it is only inbound 3G. Tried to bounce the port but does not help.
In diagnostic it does not show any error for the port. Any idea what is the reason or how to troubleshoot if 10G module of Ex , optics or fiber issue?
