CAT3K_CAA-UNIVERSALK9-M version stacking support

[Marwan Hassan]

Hi all,

 I need to know that "CAT3K_CAA-UNIVERSALK9-M" version in 3800 series supports how many switches to be stacked as I know that the initial software version supports physically stacking up to four Cisco Catalyst 3850 Switches to form a stack ring. Could you please help me out in this regard.

Thanks&Regards,

Hassan

Depends on the IOS loaded.  Early IOS will only support up to 4 switches in a stack. 

Later IOS will now support up to 9 switches in a stack.

Thanks Leo,

 I am using "cat3k_caa-universalk9.SPA.03.02.00.SE.150-1.EX.bin" so it can support 9 switches in a stack?

No.  3.2.X is the "base" version and will only support up to four.  

Starting from 3.3.X, you can stack up to nine (9).  

What’s New in Cisco IOS XE Release 3.3.0SE

• Nine-member stacks—Up to nine switches can participate in a switch stack. All switches must be running the same feature set.
