[Ranbeckycr_2]

Hi everyone,

I have been looking on the forums for the following answer:

Once I have 2 IOS images uploaded in the router how do I select which image to use?

I understand that the image is stored in Flash.  ( a link will be helpful)

I have read that I can use the command:

boot system flash slot0:image.bin

1.Is this the right command?

2. Where do I execute that command from? Privelege or config mode

3. How do I know which slot to select?

I know...to many questions, but thanks for all the help!

Hi,

boot system flash slot0:image.bin

1.Is this the right command?

- Yes the command is right if you have the IOS in slot0. Basically you have to use "boot system flash :" command.

2.  Where do I execute that command from? Privelege or config mode

- The above command to be configured in config mode and save the config Now on rebooting, the said ios will be loaded. Be aware that if you have mutliple boot statetments, it will execute in order as in configuration.

3.  How do I know which slot to select?

- It depends o where you copy the IOS to. Some devices will only have flash, while other devices support external PCMCIA cards which will be slot0/slot1 (depends on platform). When you copy the IOS from TFTP or FTP server, you need to specify the location where you will copy.

HTH,
