Boot System command for "switch 2" of stack

I have a pair of Catalyst 3750G-TS switches configured in a stack, they are running 12.2(20)SE4 IOS.

I have manually copied down an IOS to each switch by doing the following:

erase flash:

copy tftp flash:

<IP Address>


session 2

erase flash:


copy tftp:c3750-ipservicesk9-mz.122-35.SE5.bin flash2:

The "boot system switch" command is not a valid command, so I used "boot system flash:c3750-ipservicesk9-mz.122-35.SE5.bin" and it took it fine.

When I do a "show boot", I see that boot path is set correctly, but when I go in to the second switch using "session 2" and perform a "show boot", it indicates that it is pointing to the old IOS.

Is there a way to set the boot path for the second switch manually?

Re: Boot System command for "switch 2" of stack

Try using the "boot system switch all flash:c3750-ipservicesk9-mz.122-35.SE5.bin" command on the stackmaster switch. That should update the boot variable on all the switches in the stack.




Re: Boot System command for "switch 2" of stack

Mark is correct and when do a show boot is will show as both switches with the same variable . If for some reason you have a slightly different version on the second switch you can have separate boot statements pointing to the individual switch though it is reccomended that all switches run the same version.


Re: Boot System command for "switch 2" of stack

Hope you have copied the IOS properly, still see following guidelines.

1.Switch#dir flash1:

2.Switch#dir flash2:

In a Catalyst 3750 switch stack, flash: represents the Flash file system of the master switch.

3.Switch#copy tftp: flash1:

4.Switch#copy tftp: flash2:

Configure the boot variable to boot the switch with the newly copied IOS:

5.Switch(config)#boot system switch all flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin

6.Switch#write memory

Verify the boot variable:

7.Switch#show boot

Verify that the new IOS file is present in the Flash:

9.Switch#dir flash1:

10.Switch#dir flash2:


To set the boot variable for individyal switch use followign command.

3750-stack(config)#boot system switch 3 flash:/c3750-advipservicesk9-mz.


Make sure the IOS file you have copied in root directory or inside directory.

in dir flash:

you should be able to see the difference

the file ending with just like SEE1 , SEE are directories.

the file ending with like SEE1.bin , SEE.bin

are actual IOS/image files.

You need tp modify your boot variable accordingly
