Catalyst 3560 Image Update changes memory figure to Zero

I have updated the IOS on a Catalyst 3560 switch from 12.2(25)SEB4 to 12.2(44)SE2. Prior to the upgrade the memory was shown as 118784K/12280K, but afterwards it shows as 0K/8184K. How can I correct this? I have copied the output of show version below.

Many thanks

Re: Catalyst 3560 Image Update changes memory figure to Zero

Your configuration Register seems invalid.

Change it to a proper value. ie: 0x2102

(or 0x2142 if you need to ignore nvram)

Then reboot and verify the status.

If still a problem, post a 'show diag'.

Re: Catalyst 3560 Image Update changes memory figure to Zero


I dont feel its the problem with the Config Register.

The problem may be with the hardware.

Show diag would be helpful.

Also if you can reset the switch and check .

Re: Catalyst 3560 Image Update changes memory figure to Zero

This is definately a software bug. My 3560 have the same error 0K/8184K when i went from 12.2(35) to 12.2(44).
