kzahoor · ‎05-28-2022

Hi,

I have got this as my main switch however I want to upgrade the firmware as its never been updated.

I am unable to see above model to download firmware on cisco's website?

thank you

For 3750G, go with either the latest 12.2(55)SE and 15.0(2)SE train because they are famous for being the most stable IOS code.

Highly recommend downloading both (before they get removed).

thanks for that. I did find that one but it said 3750X ( I take it X is is just any version, in my case G@)

15.2(4)E train will not work. I can guarantee that. 15.2(4)E train is for the 3560E/X or 3750E/X but not for 3750/3750G.

3750G will not support anything higher than 15.0(2)SE train.

cheers for that. I am already on 12.2 so I will just leave it on it for now.
