Hi
Two switches given:
CRS354-48G-4S+2Q+
CRS312-4C+8XG
I first created a bonded interface on CRS354 but i didn’t get it to work. Then I created a bonding interface on CRS312 the same way as on CRS354 and it worked with the same host connected.
I don’t see a difference in the configs (except some quotation marks for tagged interfaces). So there must be a problem with CRS354, maybe related to http://forum.mikrotik.com/t/crs354-48p-4s-2q-traffic-problem-on-ports-1-to-8/139024/1 But single interfaces are working for me on CRS354.
Configs (removed MAC addresses and some non relevant parts, had to add both configs into same code tag)
