Problem in upgrading IOS version 15.0-SE5 to 12.2-SE12

[Aida Hadad]

hi guys,

I've just started working in company which I should upgrade Switch IOSs based on Cisco website recommendations.

Among the all Switches which we upgraded, One of them is 2960 which runs IOS version 15.0(2)SE5.

Based on Cisco recommendation I wanted to change it to version 12.2(55)SE12 but during boot up it fails .

Can we change IOS from 15 to 12?

What might be its problem?

It must to mention that I don have any log right now but I remembered it passed the post procedures and hang right CPU .. but requirement for our devices is OK .DRAM 64 flash 32

Console into the switch and reboot.  We want to see what is going on.

hi
As I said it get in to problem during boot up as passed all of post procedures successfully.
I am working in alive network with lots of staff and I couldn't do it right now. but in this weekend I should upgrade it any way cause my boss told me so.
I just wanted to know any possibility causes about situation which I mentioned above.
It must to mentioned that I couldn't simulate it so.
Many thanks for your reply

HI,

Please share the console logs.

As I said to our other Cisco friend, I don have logs and also couldn't reboot switch in live network right now.

Also as I mentioned it passed all POST procedures after booting up successfully and after that it gets to problem.

I just want any possibilities of this changing from V15 to V12...Any troubleshoots regarding that might be help full.

Please give me reply other than sending logs or rebooting to see what will happen.

Many thanks for your considerations.

Right.  I know what happened.  So you are new to this world of Cisco stuff.

So the switch boot up fine, albeit running the same IOS instead of downgrade.

Which leads me to this question:  Exactly HOW did you perform an upgrade.  

If done right, the script would've told you if things went wrong.  But it didn't.  So this means the upgrade was done using a very archaic and dangerous method (for those who don't know what they're doing) of copying the BIN file from one machine to another.  Now if this BIN file was corrupt, there is no chance the appliance is going to boot this IOS.  

Or the IOS could be pulled from a completely different appliance and copied across without any verification.

[Aida Hadad]

Hi 

Of-course before copying .bin file you must check hashing and size of that file on your system to be match with the one in Cisco site.

Then after copying that to flash you can see the exact size just with show flash.

So it can't be corrupted with those easy verification.

[Leo Laohoo]

A-ha. We're getting somewhere.
So the upgrade was just copying the BIN file across.
Show us the boot-up process.
Post the complete output to the command "dir".

Hello Aida,

As mentioned by other colleagues here already, we unfortunately depend on seeing the complete and accurate console logs from that switch. The general fact is that on a Catalyst 2960 platform, you can freely upgrade and downgrade between any arbitrary IOS versions. Since your switch behaves differently, we need hard evidence to understand what is going on. We may speculate but neither of the hypotheses will be actually useful if not paired with correct symptoms.

By the way, there is not much you could have done wrong during the downgrade. If the IOS image in the flash: filesystem has not been corrupt, we might be looking at a hardware problem.

One thing - I faintly recall that in another thread here on CSC, another user reported a problem with 12.2(55)SE12 that was similar to yours. What I would suggest is to try to go back and try 12.2(55)SE10 or 12.2(55)SE9 to see if any of them boots. To do this, I am afraid, you will need to erase the flash: filesystem and transfer the IOS image through the console port and XModem which will take hours. The general procedure is described in this document:

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/41845-192.html

Once again, however, it would be best to see the console logs and not jump to conclusions. Any attempt to recover the switch will require you to access its console, anyway.

Best regards,
Peter

The appliance is crashing.
May I recommend loading a different version. 12.2(55)SE12, perhaps?

[Aida Hadad]

I tried that one too before and it had the same log as abow

[Leo Laohoo]

RMA the appliance. Something doesn't add up.

[Aida Hadad]

I found 9 crash info in that switch but I think some of them are from the past.

all of them are same as each other and the time goes to 1993!!!!!

I think some one in past wanted to upgrade it and face to this problem too.
