I have a Switch Stack that is mixed with Cisco 2960S and 2960X switches.
How can I upgrade the IOS of the switches in the stack without unstacking it.?
Here is the steps :
So you need to prepare two different types of IOS. One for the 2960X and one for the 2960S.
For the 2960S, use the command "archive download-sw /dest 2 tftp://<TFTP IP address>/filename.tar".
For the 2960X, use the command "achive download-sw /dest 1 /dest 3 tftp://<TFTP IP address>/filename.tar".
You could also download the two different SW images but with the same SW bin versions , manually install them into the flash then reboot the stack with the new ios.
