This first happened in ROS 6.38. I have bonds to switches and servers (different vendors and different routerboards) 802.3ad (for throughtput). The bonds are always in bridges.
Untill last 6.37 all was working fine - but in 6.38 the slave ports of the bonds dinamically added to the same bridges the "master" bonds are in.
This STOPS the bonds from working. I am unable to communicate with devices connected to the switches or servers and switches connected to the bonds themselves.
In 6.38 I Was able to remove the dynamic member ports from the bridge - then everything started working again. In 6.38.1 You blocked dynamic port removal.
Logically - i think this will always be a problem (the slave ports of a bond cannot take part in communication themselves only the master bond can - so the slaves cannot be a part of anything except the master bond).
I reverted to 6.38 - removed dynamic ports from the bridge and everything started working again.
