4948 switch IOS upgrad

[JALALUDDEEN A A]

The curent ios of switch is :- cat4500-ipbase-mz.122-53.SG1.bin

I copied the new IOS on the 4948 into the bootflash directory. There is two files, the original and the new img.

OLD-HQ-TEMP-SW#show bootflash:
-#- ED ----type---- --crc--- -seek-- nlen -length- ---------date/time--------- name
1   .. image        51B30D28  EFE2FC   32 15458940 May 11 2010 01:37:15 +00:00 cat4500-ipbase-mz.122-53.SG1.bin
2   .. image        B9F04A7B 203FF78   33 18095100 Mar 30 2014 02:12:38 +00:00 cat4500-ipbasek9-mz.150-2.SG8.bin

Even though I put the command boot system flash bootflash:imgname it still boots the old ios.

When i changed the config register  to 0x2102 and boot with new image and  reloads. It going to rommon mode. so please help me to do this

I realy want to upgrade this to the latest release and I am having a hard time

Hi,

What model of Catalyst 4948 do you have? The IOS version you're trying to install only supports the Catalyst 4948E switch. If you've an older non E model then you'll not be able to use this IOS release.

Model of the switch is cisco WS-C4948.

i just copied the ios through tftp and boot with the flash. Dont know how come all 3 statements come. And also how to delete or change that bootvariable.

Apologies. My mistake the switch model you have is supported with this release.

Glen is exactly right here in that the boot statements you have look to be the cause of the problem. If you execute the command show runn | in ^boot you should see a number of statements which are reflected in your boot variable. You'll probably see a number of entries such as boot system bootflash:cat4500-ipbasek9-mz.150-2.SG8.bin, boot system tftp cat4500-ipbasek9-mz.150-2.SG8.bin 255.255.255.255 etc.

To remove those that you don't want you simply add the no keyword to the begining of each line that is not required. You also need to change the configuration register, and then save the configuration.

So the following configuration should be what you need:

no boot system tftp:cat4500-ipbasek9-mz.150-2.SG8.bin 255.255.255.255
no boot system booflash:cat4500-ipbasek9-mz.150-2.SG8.bin
config-register 0x2102
end

After you exit config mode, save the configuration and reload.

  It looks like you have three boot statements in there .  Get rid of all of them except the one you want.  Also in your show bootvar  statement  bootflash is not spelled correctly possibly the cause of your issue. Not sure what booflash is  :-) .   As long as your config register is now 0x2102 and your boot statement  is correct it should work.
