How to OS Upgrade Cisco Catalyst 9200/9300 Series Switch

 

Firmware Upgrade for Catalyst 9200 and 9300 Series Switches

When you upgrade to a newer release of the firmware or operating system on your switch, the boot loader may also be updated automatically, depending on the hardware version of the switch. This updated boot loader will come into effect the next time the switch is restarted or reloaded.

Follow these instructions to upgrade from one release to another in install mode. To perform a software image upgrade, you must boot into IOS through boot flash:packages.conf.

Step 1: Clean-up

install remove inactive

Use this command to clean-up old installation files in case of insufficient space and to ensure that you have at least 1GB of space in flash,

Switch# install remove inactive

install_remove: START 

Cleaning up unnecessary package files

Do you want to remove the above files? [y/n]y

Step 2: OS upload in to the flash 

Switch# copy tftp://10.8.0.6/image/cat9k_lite_iosxe.17.09.05.SPA.bin flash:

or

Switch# copy usbflash0:cat9k_lite_iosxe.17.09.05.SPA.bin flash:

Switch# dir flash:*.bin

Verify the image using md5  

Switch# verify /md5 bootflash:cat9k_lite_iosxe.17.09.05.SPA.bin

Step 3: set boot variable

Switch(config)# boot system flash:packages.conf

Switch(config)# no boot manual

Switch(config)# exit

Switch# write memory

Verify the BOOT variable

Switch# show boot

BOOT variable = flash:packages.conf;

Manual Boot = no

Step 4: Install image to flash

Switch# install add file flash:cat9k_lite_iosxe.17.09.05.SPA.bin activate commit

install_add_activate_commit: START 

This operation may require a reload of the system. Do you want to proceed? [y/n]y

Step 5: Verify installation

After the software has been successfully installed, use this command to verify that the flash partition has four new .pkg files and two .conf files.

Switch# dir flash:*.pkg

Switch# dir flash:*.conf

Directory of flash:/*.conf

Directory of flash:/

16631 -rw- 4882  Apr 25 2024 05:39:42 +00:00  packages.conf

16634 -rw- 4882  Apr 25 2024 05:34:06 +00:00  cat9k_lite_iosxe.17.09.05.SPA.conf

Step 6: Reload and verify version

Use this command to reload the switch. When you boot the new image,

Switch# reload

After the image boots up, use this command to verify the version of the new image.

Switch# show version

Cisco IOS XE Software, Version 17.09.05

Cisco IOS Software [Cupertino], Catalyst L3 Switch Software (CAT9K_LITE_IOSXE), Version 17.09.05, RELEASE SOFTWARE (fc1)
