lacp performance degradation



We are currently in the process of activating lacp profiles for our IAP-225's following the configuration provided by madjali in this post.


The issue we are seeing is after the third port channel, the MAS becomes unresponsive for a few seconds, after the fourth putty will time-out every time we add a port to the port-channels. After the fifth the MAS will stop responding to pings every 30 seconds or so and causing all connected devices to lose the network.


Is there there a step we missed during config? We have experienced this on more than one stack. We are running IAP v. and MAS

Total shot in the dark -- the first place I'd look is to see if the switch uplink is going through some sort of spanning tree state transition.
