Upgrading IOS on 4500x Switches

[c-davies]

Hello,

I need the crypto version of IOS for a VSS pair of 4500x-32 port switches.

I tried what I thought was the usual upgrade process.

tftp image to bootflash: and slavebootflash: and config to boot system flash blah.bin

wr mem

reloaded both switches.

on Bootup the cli simply says using 1st file on flash.

I followed the process which wanted to change the config-register to 0x2102 for some reason? and a redundancy peer reload, this simply put my swithes into rommon mode.

Whatever process I try the switches will not load the same version k9 crypto file, its simply ignored. Are we back to the old days of having to order the image on the bootflash?

Please help if anyone knows how to upgrade these switches, they are not production yet in pre-stagng so uptime is not important yet.

My current version is -

System image file is "bootflash:/cat4500e-universal.SPA.03.04.00.SG.151-2.SG.bin"

I want to load

cat4500e-universalk9.SPA.03.04.02.SG.151-2.SG2.bin

Which exists on the bootflash and slavebootflash

Thanks

Chris

Hey c-Davis,

Just saw this post- I follow the below method to upgrade 4500 with dual sups-

copy the image to bootflash& slavebootflash

!update the boot statement

conf t

boot system flash bootflash:

(needs to set the conf reg to 0x2102 if its set to other value)

end

wr mem

!!reload the entire box

redundancy reload shelf

this will reload the entire box and it will come up with the new image.

Cheers!

George

Has anyone tried using the "changeversion" functionality on ISSU; one command step?
