Change supervisor from standby on Catalyst 4500

[CiscoBrownBelt]

So experiencing difficulties loading new image on 4500 series switches.

 One issue, I want the top supervisor to be the primary not standby. ANyone know how to change this?

Also, I did:

no boot system flash (old image)

boot system flash (new image)

copy run start

reload

but old image is still used upon reboot and the "show boot" will display both images as the boot image.

Anyone know how to fix this?

I have followed in the past below document, and work like charm.

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/27848-179.html#task1

Paste below output to understand better :

show bootvar

show bootflash: 

show slavebootflash:

show redundancy states

I am basically trying to upgrade the image on a dual sup 4510 switch.
It still loads old image, but now the other sup status ligh blinks amber and does nothing (shows nothing, unable to enter commands, etc.) when consoling into this supervisor.
Any ideas?

Question, so I am working with a 4510 dual sup. On the copy source_device:source _filename slot0:target_filename command, what do I put for source_device:source_filename?

[balaji.bandi · Accepted solution]

source_device:source_filename

source_device : this can be any thing like , USB / TFTP / FTP or any other

source_filename : the filename you like to copy. example IOS.12.X.bin

You need plan and understand detailed steps for the upgrading path.

you should take some precaution measure steps, while you doing core switch in your case 4510 for the IOS upgrade.

also keep upto date your backup plan if it fails, how fast you can restore to old setup, with out any service interruption.

do all the task in maintenance window. technically not expected any long down time, there will be small network switch over and network convergence.
