here is my real life experience. I tried stacking switchs with mismatched IOS and they didn't work together at all. Another time one master tried to update a new switch memember and it got so hosed Cisco told me to just RMA it because it couldn't be fixed.
Another time I tried upgrading the master and then I ended up with one switch by itself and the other switches formed their own stack even though they were all cabled together.
The "Stackwise" technolgy is nowhere near as pug'n'play as Cisco would make you think it is and there are a lot of gotcha's to this stuff.
Hint. If you use the GUI to do upgrades it puts the software in all the right places. The flash has the IOS stashed in a dir named after the IOS image which is confusing.
If you don't use the GUI you have to carefully load the new IOS on all the switches in the same flash location and remove the old IOS. It's a pain but workable.
I agree its tricky at best , you are better off doing a manual copy from the master down to the other stack members flash and then reload them.I have never figured out what versions you could use together and what is a major and minor version revision number. They could have taken a lesson from the old Bay hubs where you had the top master and you just plugged them into the back and the master controlled the rest with no intervention. 3750's can be a pain sometimes .
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
