Solved: Re: Show Version command displays old IOS on Cisco 4948? - Page 2

cdalask · ‎11-25-2009

Recently upgraded our Cisco 4948 with no apparently problems. The switch appears to be opperating fine. However when you enter "show version" it still shows the old IOS. When you enter "show config" or "show running-config" it shows the upgraded version. How do we correct the "show version" command to display the current IOS?

Thanks,

Can you post

1) "sh run" from switch

2) "sh ver" from switch

3) dir flash or dir bootflash from switch

What do you see on the console when you reboot ie. does it even try to load the new IOS ?

Jon,

When it does attempt to boot at the rommon prompt I can see it attempt several times before I have to type "boot" at >rommon. Below are the commands you requested:

You have to re-do your boot statement with the following command

conf t

no boot system flash cat4500-ipbasek9-mz.122-53.SG1.bin
boot system flash bootflash:cat4500-ipbasek9-mz.122-53.SG1.bin

exit
wri mem

Please post the output of show boot before you reboot your 4948.

Regards,

jerry

cdalask · ‎11-30-2009

I noticed you entered the word bootflash:/ with a slash before the filename. This could be where I'm missing the boat because it doesn't show "bootflash" when I use the auto complete feature. I have been entering #boot system flash cat4500-ipbasek9-mz.122.53.SG1.bin and I haven't been entering a forward slash! I will give it another try once you confirm my reply.

Thanks,

~c

You shouldn't need the / but from memory i don't think it matters either way. Don't use the auto complete feature at the moment, just type it in manually and make sure you save it to memory. You just need to confirm it is in the running config with bootflash in the string before you reload the switch.

Jon

cdalask · ‎11-30-2009

Success! I believe my error was not entering the word bootflash: after boot system flash. Thanks for your support and patience!

You still have the wrong boot statement in your config. Do this

4500(config)# no boot system flash cat4500-ipbasek9-mz.122-53.SG1.bin

4500# wr mem

then do a "sh run". You should not see the boot system flash statement that is there at the moment.

Then

4500(config)# boot system flash bootflash:cat4500-ipbasek9-mz.122-53.SG1.bin <--- note the additional "bootflash" in the statement

4500# wr mem

then do a "sh run" again and you should see the new boot system flash statement.

Then reload the switch.

Hi,

Have you solved the problem or not yet?

glen.grant · ‎11-25-2009

Jon is correct because the config register is 0x2101 the boot statement you entered will do absolutely nothing. 0x201 means it will just load the first image it finds in flash which is your old image because it was not deleted . As Jon indicates change the register to 0x2102 and reload and it will load the newwer image.

OH SNAP!!!!

Sorry... I had too!!!

glen.grant · ‎11-25-2009

Jon what do you mean the original post looks correct ? :-)

rupam_chakra1983 · ‎11-25-2009

The problem can be due to this

1. From the "rommon" mode try to change the configregister

you can use the command " confreg"

reset

and then check whether the config register get changed or not.

If once the config register get changed via this your problem will get resolved

Thanks
