Solved: Cisco Catalyst 3750 Series Stack IOS Upgrade

egemen1981 · ‎10-08-2012

I have Cisco Catalyst Stack structure that consist of;

3750E-48TD-S (MASTER) (UNIVERSAL Image)

3750G-48TS-S (IPBASE Image)

I want to upgrade their IOSs to k9 images.

I can not dowload Universal Image file from Cisco website because of the expired service contract. I have IPBASE IOS files for all switches,

Can it be a problem to upgrade master switch IOS from Universal to IPBASE image?

Regards.

Hi Egemen,

Yes,You can downgrade from Universal to IP base.

I would start with upgrading the 3750Gs (if you are allowed to use on alls witches ) to the Universal(If you have)

if you can not upgrade the 3750E then downgrade the 3750E to the same version as the others.

It is always better to use same IOS on a stack.

Regards

Please rate if it helps.
