Hi,
we upgraded the release from 2015 Jul to the latest version.
For now, ipmp doesn't work anymore, I had to deactivate all port exept one of 
course.
Since we use standby links, the traffic should only occur on this port and the 
other should be STANDBY.
We found out, that in september 2015 there were changes in the ipmp and also 
one new command has been invtented. (if_mpadm).
After activating all links (incl. Standyports), all interfaces produce traffic 
and we have DUPs  checking via remote as well as enormous amounts of 
congestions.
Dladm show-vnic shows, that it uses multicast with an random MAC address. So 
far so good. But ipmp seems not to check that other interfaces are standby and 
the traffic seems to be routed trough the standby links but outgoing from the 
online interface. This is good for RR but not for standby mode.
Is there a major bug in the IPMP implementation ?
We are debugging right now for further information.


Rgds.

Franz
