LACP Bonding over bridge issues

Hello everyone,

I have Mikrotik RB1100AH and trying to configure LACP bonding for Synology NAS with 802.3ad support. NAS is plugged directly into router ports 4 and 5. Bonding of these ports is configured as follows:

/inteface bonding add slaves=ether4,ether5 mode=802.3ad lacp-rate=30secs link-monitoring=mii-type1 transmit-hash-policy=layer-2-and-3

(based on the wiki)

I want my NAS to be accessible from LAN which is connected to port 1 on the RB so I just add bonded interface to a bridge with port 1. After doing so it works … partially. Connection to the NAS is unstable and it tends to drop packets (up to 25% total). I wonder what might be a cause of the problem… is this my misconfiguration or something else? Or maybe there is some other way of achieving 802.3ad with my setup?

Any help would be greatly appreciated.

I have the same problem as you, to see if someone gives us a solution …
