I actually went through the chapter before I came here. It did not really tell me what is wrong with my stack ( two switch stack)

How are your stack cables connected?

It doesn't look like you have a valid connection between your stack ports on the back of the switches. Make sure you use TWO stacking cables to fully close the loop on your stack.


I strongly suggest powering off the switch that isn't properly configed (the second switch in your example?), rechecking your cables, and then powering back on and seeing if it joins the stack.


The election process can come to a decision junction at which point it selects the switch with the longest uptime- and this may inadvertently cause you a lot of headache.

this is how the cables are connected:


switch1/port1 -> switch2/port2

switch1/port2 -> switch2/port1


and I noticed the switches have detected stack connection during boot up process. If the cables are not connected at all, the port status should be showing as absent, right?

Per your output, it shows the stackport status shows down. This is the physical connection that allows the stacking to take place.


Did you connect the stacking cables per the diagram on the documentation I provided?

yes I did. If the cables were not connected at all, the port status should have been showing as absent, according to the documentation

I have exactly the same problem. There seem to be a lot of people with a similar problem in the 'Support Community' but no real fix or solution. If anyone can help, please...

Power down the secondary switch. Unprovision it from the configuration if it has it listed.


# config t

# no provision xxxx


Upgrade the IOS to 12.2.55 latest on both switches manually. Reboot and make sure both are running the same code. Power down the member switch and make sure the stack cables are plugged in tightly in the manner you have Switch1 port 1 <-> Switch2 port 2 and vice versa for full duplex connection.


Once stack ports connected, power up the member switch and check status. I always perfom it in this way to minimize problems.
