i purchased a new 2960-X switch
i would like to add it to an existing 2 switch 2960-s stack
i understand i need to downgrade the stack speed on the 2960-x with :
switch stack port-speed 10
do the IOS version need to be identical on all switches?
2960-s = 12.2(55)SE3
2960-x = 15.0(2)EX3
if they do need to be identical, whats the best way to do this?
Yes, use this command with a .tar file to upgrade all switches in the stack.
Here is an example of using the `archive download-sw` command to upgrade a stack of Cisco Catalyst 2960-S switches. Notice that the number of members in the stack is not relevant to this command. By default all members are upgraded unless the network admin uses the options to do otherwise. The TFTP IP address is 192.168.1.1, and the tar file name is c2960s-universalk9-tar.122.53.SE.tar
