Configuration register is 0x2101

Forget it.  I know why.  

Configuration register is set to 0x2101.  This is the DEFAULT value of a supervisor card fresh from the factory.  The last octet "1" means disregard boot variable string and boot the first IOS found in the bootflash.   

Change the configuration register to 0x2102 and you should be fine.

Hi Leo,

Thanks

Before restart is necessary to put the command :

no boot system flash bootflash:cat4500e-ipbasek9-mz.122-53.SG.bin(old IOS)

I wouldn't do that, if I were you. 

Your boot variable stable should be the following: 

boot system flash bootflash:NEW_IOS.bin

boot system flash bootflash:OLD_IOS.bin

This will ensure that your chassis will recover if the new IOS doesn't work. 

Don't forget to rate our useful posts.

Hi,

Now show bootvar:

cat4500e-ipbasek9-mz.150-2.SG10.bin New IOS

cat4500e-ipbasek9-mz.122-53.SG.bin OLD IOS

Core_1#sh bootvar
BOOT variable = bootflash:cat4500e-ipbasek9-mz.150-2.SG10.bin,1;bootflash:cat450
0e-ipbasek9-mz.122-53.SG.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2101

Now will I put the command

Configuration register is 0x2102 and reload the switch, switch will boot with the new IOS

am I right?

After you change the config-register value, please don't forget to save the config. 

Otherwise, you're good to go.
