3.2.x.x firmare has the ability to set a stacking module port to be an ethernet port and CX4 module port to be a stacking port. It looks like your first switch has at least one of its stacking module ports (xg2) set to be an Ethernet port.  This may happen because at one time you had a non-stacking module in this slot or you plugged in a stacking module while the switch was powered on.  Or it is a bug.  Either way, here is something to try: Use the following commands to set the stacking module ports to stacking ports. stack-port 1/xg1 stack stack-port 1/xg2 stack You may have to save the configuration and reboot. Just curious, did these switches come with 3.2.0.7 firmware on them or did you load it yourself?
Hi all. I have 2 6224: one already working and the second one tath i want to stack with the first. I followed those steps: -configure priority 12 on the first switch (the one i want to be master) -power off both switches and add stack module -connect stacking cable from 1/xg1 of the first switch to the 1/xg2 of the second one -power on both switch  but nothing happened!!!!!! The switch doesen't recognize the topology change. I tried to connect the stacking cable while the switch was powered, to change ports, to change cable but there is no way....   What do you suggest to do??   Thanks in advance! Stefano
6224 Stack won't work!
