E5500 - 03-03-02s168ep21.app - Checksum is different from unit1's

Hi,

 

Has anyone come across this in the latest code, after applying to a stack and saving, whilst the save appears to update the config file there is a message:

 

-Unit2's checksum is different from unit1's.  This is also for any other units in the stack.

 

I notice that in release notes it appears this used to happen in an older version of the code, but was fixed back then - LSOD08674.

 

Anyone know how to resolve this checksum error?

 

Thanks!

You will have different configuration on the switches. Perform a diff of the saved configurations from each unit and it should quickly become apparent where it's broken.

I have the same problem after update the software to the last build (p21). I got the problem on two stacks. If never seen this error before. I deleted the config files in flash and did a new save, but problem still exist. What can I do to solve the problem?

It has to do with the new cipher algorithm, it's a little buggy.

 

Just look at your configuration and copy & repaste all lines that you have with "cipher" keyword.

 

For example:

 

Current config: "

user-interface aux 0 7
authentication-mode password
set authentication password cipher $c$3$XPTOXCPTCPTOXCPTO==

"

just go to:

 

[4500]user-interface aux 0 7
[4500-ui-aux0-7]set authentication password cipher $c$3$XPTOXCPTCPTOXCPTO==

 

and then save

Code 3.3.2p22 is now available and  should contain the fix "cipher" issue when saving configurations in stack

I've upgraded with the new firmware (3.03.02s168p22) & have the problem  with 3 of the 4 switches in the stack having a different checksum to unit1. I have recopied the .app file on all units to overwrite the originals & while the same file has worked without error on 4 other stacks, I have a problem on my main stack.

Any advice would be hepfull.

I have changed all my local-users password for the type password simple and the issue remains the same.
