ios upgrade on switch stack

Answered Question
Nov 22nd, 2013
User Badges:

We have a stack of three switches.

Two are 3750E switches which use the universal ios and one is a 3750G switch which does not.

they are all at same version 12.2.55 SE3                  


i think when we built the stack we installed the ios individually but now we want to upgrade the stack preferrably with taking it apart.


the stack master is the 3750G switch.


we tried using the archive download-sw and no joy.


is there a procedure we can use to upgrade the ios on the stack that will work ?


thank you in advance

If you are goal is to upgrade the stack. Copy the image from the tftp server to all the flashes.


copy tftp:///image-name.bin flash1:image-name.bin

copy tftp:///image-name.bin flash2:image-name.bin

copy tftp:///image-name.bin flash3:image-name.bin


change the boot sequence


conf ter

boot system siwtch all flash:

end

wr mem


reload

Since two of the swtiches have different images do I put different boot statemetns in each switch ?


is there no way to do with the archive command.


someone said we could use this ?


archive download-sw /overwrite tftp:/3750e image.tar  tftp:/3750G image.tar

There are several ways to upgrade the IOS of a 3750.  What Karthick has posted is an old-school method and would work if you only have the BIN file.


If you have the TAR file, the best (and most effective) method is this command:


archive download-sw /destination 1 /destination 2 /destination 3 tftp:///filename.tar


You can add the following options:


/overwrite - Delete the OLD IOS subdirectory.  If your old IOS is a BIN file in the boot directory, then this file will be left intact.  If you have more than one old IOS subdirectory, only one subdirectory will be deleted. 


/no-set-boot - Do not set the boot statement.  By default, boot statement is always changed by this script.
