Answered Question
Feb 2nd, 2014
User Badges:

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?

i have:

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?

thanks

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

Switch# archive download-sw tftp://192.168.1.1/c2960s-universalk9-tar.122.53.SE.tar

You need the same version of IOS for the whole stack.

Make sure you upgarde or downgrade to have the same version before mixing them

The easiest and shortest way of doing this is by loading the same IOS to all switches, have an outage window and reboot the stack.  These devices take about 5 to 7 minutes to reboot.  If you do everything a head of time and have it  ready, an hour outage window should do it.
