After several days on the lab I have got a Smart Install and Automatic Smart Ports Zero touch configuration almost ready to deploy on our network. I am just having a last issue.
The configuration of my 2960S is ok and they detect other switches on the ASP ports and everything is fine.. BUT.. after about 2.40mns with no cables being unplugged the switch forgets that port gi1/0/6 fx has a Catalyst Switch connected to it and discovers one unclassified device executing CISCO_LAST_RESORT_EVENT macro which has other access ports and so on.
I have no idea what could be triggering something like this. I have ried several debug commands but nothing seems to be the trigger.

Hope someone can give me a clue on what could be causing this.
I have gone further on investigating and the switch receives information about all the devs that are on the neighbour switch and takes actions according to it.

My Gi1/0/6 is Uplink to one other Auto Smarports device.
I have tried to stop macro auto processing on the neighbor switch but that doesn't help.
Someone could help on how to solve this - maybe some turn around? Could that be an IOS issue?
