<div dir="ltr">Salman,<div><br></div><div> For FCX (and ICX6610 unless you need mixed family stacking) you should stick to the 7.3.0 code train. I recommend going to 7.3.0h. 7.3.0j is newer, however I had stack communication issues with it (just like you're seeing with 7.4f).</div>

All of them are stacks. After upgrading to 7.4f we have seen a lot of stack sync issues. The standby unit in all the cases seems to be the source of the problem. Rebooting the stack causes the standby unit to go unresponsive unless the unit is hard rebooted. The show stack connection command shows the following.<br>
