Cisco 3850 bundle mode

I have a stack of six 3850 switches. One is in BUNDLE mode and the others are in INSTALL mode. How do I change the one switch so all are in INSTALL?

Switch Ports Model SW Version SW Image Mode
------ ----- ----- ---------- ---------- ----
* 1 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 INSTALL

Hi bmartin1000,

Hi bmartin1000,

A good approach in order to accomplish that task is to enable the "software auto-upgrade" feature in your stack and then reload the switch with the software mismatch (in your case SW6).

 

(config)#software auto-upgrade enable

 

The following link contains more information on this process:

Hope this helps! :)

The "software auto-upgrade"

The "software auto-upgrade" command says no switches are running incompatible software.

If that didn't do the trick,

If that didn't do the trick, you will need to perform the following steps:

 

1. Remove SW6 from the stack

2. While the switch is standalone extract the .bin (bundle) file with the "software expand file" command (this will create the "packages.conf" file)

#software expand file flash:cat3k_caa-universalk9.SPA.03.02.03.SE.150-1.EX3.bin to flash: 

Note: Before extracting the .bin file, confirm that no other "packages.conf" file has already been created within the "flash:" due to older releases; if there is one remove it. 

3. Change the boot statement and point to "packages.conf" then save the configuration:

3850(config)#no boot system 
3850(config)#boot system switch all flash:packages.conf
3850(config)#exit
3850#wr
Building configuration...
Compressed configuration from 5062 bytes to 2695 bytes[OK]
3850#	

 

4. Reload the switch and verify it is on the Install mode

5. Add it back to the stack

 

Let me know if you have questions on the above steps.
