Step 1: Need to clean old installation files in case of insufficient space and to ensure that you have at least 1GB of space in flash, to expand a new image
NDNA_Switch# install remove inactive
Step 2: Copy the new IOS file to each switch flash through TFTP.
NDNA_Switch# copy tftp://10.10.10.1/cat9k_iosxe.17.09.03.SPA.bin flash:
Where 10.10.10.1 is a TFTP server
Check the flash now
NDNA_Switch# show Flash:
Step 3: Verify md5 hash file for new IOS file.
NDNA_Switch# verify /md5 flash:cat9k_iosxe.17.09.03.SPA.bin
Step 4: Configure the boot variable as below.
NDNA_Switch(config)# no boot system
NDNA_Switch(config)# boot system switch all flash:cat9k_iosxe.17.09.03.SPA.bin
NDNA_Switch# end
NDNA_Switch# wr
Step 5: Verify the boot variable is configured correctly.
NDNA_Switch# show boot system
Step 6: Need to create packages and install the new IOS.
NDNA_Switch# install add file flash:cat9k_iosxe.17.09.03.SPA.bin activate commit
Note: It will prompt for (Y/N) we need to press Y. Switch will automatically reload once execution of above command completed. This command will also copy new IOS file in standby switches.
