Most Stable IOS for Cat 3750 - Cisco Lab

[sean.cline]

As the title states, what is a good IOS version to stick on a 3750 (normal, no X or G series) switch? This is being used for a Cisco Lab in my CCNP - SWITCH studies.

Normaly I referance INE's site though they dont have a 3750 (only 3560) IOS recomendations.

122-55 is the latest on Cisco.com and seems to be pretty stable..

IP second Reza's recommendation, 12.2(55)SE7 is, currently, THE most stable IOS around.

If you need 15.0, then you can try 15.0(2)SE2.

Thank you for that information, I will upgrade to that revision. I don’t believe my model however supports IOS 15 code, at least I don’t see it on Cisco's download page for the switch "Cisco Catalyst 3750-24TS" or would installing the 15x code from say 3750-X model theoretically work (non-production of course).

If your applliance has 16 mb flash, then the highest version is 12.2(55)SE and later (like SE7).

If your appliance has 32 mb flash, then you can go as high as 15.0(2)SE and later (like SE2).
