Upgrade 4510R+E with Sup8

Hi,

I have this 4510 switch with 2 Sup 8s.

Currently running this firmware : cat4500es8-universal.SPA.03.08.04.E.152-4.E4.bin

 

Can I install a k9 firmware to allow SSH support on this?

I am installing : cat4500es8-universalk9.SPA.03.09.00.E.152-5.E.bin

 

Going to do upgrade without changing the config reg, by renaming old firmware to .BAK.

There are no dependencies in upgrading from non-K9 to a K9 image. So you can proceed with the upgrade. 

 

I am not sure why do you want to re-name your old firmware. If that is your general practice then go ahead. Else, you just need to change the boot variable pointing to the new image and remove the previous one.

 

Something like this:

 

no boot system

boot system flash bootflash:cat4500es8-universalk9.SPA.03.09.00.E.152-5.E.bin

 

4500#show bootv

BOOT variable = bootflash:cat4500es8-universalk9.SPA.03.09.00.E.152-5.E.bin,12;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x2102

Hi Thank you!
I tried this method, but had to change the confreg to 0x2102 ( as it was still pointing to 0x2101).
Force reloaded the peer and waited for it to come up. It came up as RPR (Cold Standby).
Made sure standby had the latest firmware.
Did "Redundancy force-switchover" and it took a about 5mins to come up.
Strange thing is that the switchover did not work, it came back to primary sup with downtime, but firmware came up ok and changed to SSO after few more minutes. Is this expected?
