Cisco 9200 Stack Switch Firmware Upgrade with USB flash drive

-

 1. Download the new firmware from the following link.

https://www.cisco.com/c/en/us/support/switches/catalyst-9200-r-series-switches/series.html#~tab-downloads

2. Copy the file cat9k_lite_iosxe.17.03.05.SPA.bin into the USB flash drive.

3. Connect the USB flash drive to the stack master switch and console it.

4. Before you do anything, backup all the configuration of the switches

5. Login to the stack master switch and check the mode using "Show Ver". In this case, it is running the install mode.

6. Remove unwanted Packages

C9200#install remove inactive

7. Copy new image into the flash

C9200#copy usbflash1:cat9k_lite_iosxe.17.03.05.SPA.bin flash:

To verify: C9200#dir flash:*.bin 

8. Set Boot Variable (Change Boot Mode from Bundle to Install Mode)
C9200(config)#no boot system (For bundle mode)
C9200(config)#boot system flash:packages.conf
C9200(config)#end
C9200#wr
C9200#show boot system

9. Software Install Image to Flash
C9200#install add file flash:cat9k_lite_iosxe.17.03.05.SPA.bin activate commit

After hitting 'y', you'll be asked to confirm that you have changed the boot config to packages.conf. You'd have done this in step 8.

Confirm by hitting 'y'. Your screen will produce a similar output and requires a reload. 

10. Verify New Packages and Image after reload

C9200#dir flash:*.pkg

11. Check the Version and New Bootloader

C9200#show version

C9200#show boot

12. Clean up

C9200#install remove inactive
