IOS load failure for Cisco switch 2960

Nabaruma

I have a Cisco 2960 switch that has an old ios (c2960-lanbase-mz.122-25.SEE2.bin) which i want to replace with a new ios (c2960-lanbasek9-mz.122-55.SE.bin) which I successfully uploaded from my tftp server.

The new ios has been uploaded to the switch flash and boot change to the new ios (using the command: boot system flash:) but the switch still load from the old ios even after reload.

I have reloaded several times and even tried using this command ( no boot system flash:....old ios...) but all to no avail.

Someone please should help.

Thanks guys in advance.

Jon is correct missing boot statement

2960(config)# boot system flash:c2960-lanbasek9-mz.122-55.SE.bin

2960(config)#Wr mem

2960(config)#show boot

Run show boot to verify that boot statment is set prior to reload

you should see a statement that says "boot=" or BOOT path-list

2960(config)#reload  < will reload the switch and apply new image, since you stated its a live network, schedule a maintiance window and do it afterhours

Best of luck!

Why not delete the old IOS?

Nice suggestion, but it's actually a live switch and I'm scared to take that risk!

Can you post -

1) "sh version" from switch

2) dir /all or dir bootflash: from the switch

3) the running config of your switch

Jon

Hi Jon,

I have triend show boot ealier and it showed the booting is on the new ios.

Anyway i have attached the commands that you said i should run on the swicth.

Thanks,

Usman

I cannot see any "boot system flash" command in your running config ?

Please add this to your config and try reloading again -

2960(config)# boot system flash flash:/c2960-lanbasek9-mz.122-55. SE.bin

Jon

Hi ALL,

I'm alright now. The swicth has loaded the new ios after using the following commands:

#no boot system flash:c2960-lanbase-mz.122-55. SE.bin

#boot system flash:c2960-lanbasek9-mz.122-55. SE.bin and reloaded.

I really appreciate you all.

Thanks,

Usman.

No problem, glad you got it fixed.

Hi Usman,


try "show boot "

this will tell you the boot variable, boot loader and configration registor. This way you can verify the boot variables before reloading

Pretty usefull command

Hope that helps.
Prag

========================
show boot

Use the show boot privileged EXEC command to display the settings of the boot environment variables.

show boot [ | {begin | exclude | include} expression]
