SOLVED: Is it possible to transfer FGS switch flash to another switch?

[ Edited ]

I notice when I download the flash to tftp the image is different.  It's 32 bytes larger.  Is it possible to download the image from a switch and upload it to another switch?

 

FGS624XGP-POE

 

The reason I ask this is because something very suspicious is going on with my switches.  I am getting random host logging lines in the config.  The ports are invalid port numbers so I cannot no out the lines.  Even if I upload a new config, those entries come back.  The only way to clean this out is to re-writre the flash, power cycle, and then upload the new config.  A reload will not work.  It just comes back, hours or days later.  I found it strange that the image signaures were different from the stock when I download them from the switches.

 

This situation is acting like a worm.

Re: Is it possible to transfer FGS switch flash to another switch?

There are two issues here ...

1. tftp image from a switch to yourr tftp server and getting incorrect file size.  

     This has happened to me as well and can NOT really find the reason for it,  Make sure the file size is the same when copy to tftp server.

      If the download is ok, you can copy it from tftp server to another switch and it shuold work fine, otherwise, the image will not boot correctly due to file corrruption.

It is best to download images from MyBrocade to your tftp server and then tftp that image to other switch to avoid the issue above.

 

 

2. host logging added randomly in config

     is it something like the following

...

logging host ipv6 0:cccc:100:ccc4:0:cccc:0:cccc udp-port 1073794252
logging host ipv6 101:cccc:0:cccc:2:c8cc:0:cccc udp-port 183500
logging host ipv6 200:cccc:2:cccc:300:cccc:0:c8cc udp-port 52428
logging host ipv6 2:cccc:0:cccc:0:cccc:0:cccc udp-port 33737932
logging host ipv6 1:cccc:0:cccc:0:cccc:0:ccc4 udp-port 52428
logging host ipv6 0:cccc:0:cccc:0:cccc:0:cccc udp-port 33604812
logging host 0.2.204.204 udp-port 51404
logging host 0.0.204.204 udp-port 51404
logging host 0.0.204.204 udp-port 52428
logging host 0.0.204.204 udp-port 33606860
logging host 0.0.204.204 udp-port 52428
logging host 0.34.200.204 udp-port 268487872

 

This is a known defect, please upgrad e to FI 7202m, posted on 8.25-14, for fix of Defect517795

Yep that is exactly what it looks like.  I've already started updates to ver m, getting rid of the logging was a bit tricky.  I had to develop procedures in a specific order.  At first I was having to power cycle the switches to get rid of it after the update, but then we figured out it would go away if we removed the logs and logging persistance.

 

Thanks!

 

No luck with the file image size thingy though.  No matter what I do the image is 32 bytes larger.  I have the firmware from Brocade so I can still do it.  Strange though.  I'm going to take a look at it with a hex editor and see if all the bytes change or it just adds 32 bytes to it.  If so, it should be easy to code a little program to fix them.
