Cisco 3850 bundle mode

[Brad Martin]

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
2 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 INSTALL
3 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 INSTALL
4 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 INSTALL
5 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 INSTALL
6 56 WS-C3850-48P 03.03.02SE cat3k_caa-universalk9 BUNDLE

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" command says no switches are running incompatible software.

Ran this command with this result.

software expand running to flash-6:
% Failed to establish communication with switch 6, operation aborted

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.

Thanks for the info. I will try it when I am on-site next week.
