I found a previous post relating to this subject that did not answer my issue...viewtopic.php?t=110400
I am using a CCR1036-12G-4S (6.37.4) and bonding 2 SFP modules to a Cisco Nexus 3064 switch. The bonding does not seem to be working properly. I expect it is an issue with the Mikrotik configuration as I am seeing data coming from the switch on both ports, but data originating from the Mikrotik is only traveling on one interface. I have 2 devices on the other side of the switch that are both generating/receiving data (Each device is on a different network and segmented via VLANs). While I would not expect to see even traffic flow on the Ethernet Interfaces, I would expect traffic on both.
