All switches have been upgraded to the latest firmware (15.1.1.6). On first boot, the stack links were up and the stack was configured with easy-setup. Configuring and rebooting the stack several times was working, the stack always came up again, all stack-ports up. But as soon as I powered the switches off and on, the stack-ports did not come up again and I ended up with 8 master switches with no links between them. After a long time of searching for a solution, I found out, that I was able to reactivat the stack-ports by doing a "run diag stack". The whole procedure was repeated several times, always after powering off and on the stack-ports did not come up again...<BR /> <BR /> Somebody ever saw anything like this?<BR /> <BR /> Best regards JAN<BR /> <BR /> (from Joerg_Anliker) Wed, 08 Jan 2014 05:52:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/stacking-problem/m-p/58870#M17434 EtherNation_Use 2014-01-08T05:52:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/stacking-problem/m-p/58871#M17435 Create Date: Apr 25 2012 1:59AM<BR /> <BR /> Me again...<BR /> <BR /> Seems to be a problem with 15.1.1.6.
