Cisco IOS EOL

I'm currently tracking on software currency  and  not able to find EOL info on the IOS below. Can anyone help? Thanks.

12.2(35)SE.

12.4(13r)T10

IOS itself doesn't really have an EOL date. It's more about the hardware that you're running it on. In the case of 12.2(35)SE, that software can be found on switches ranging from the 2960G all the way up to the 3750E. The last one of these to get EOLed was the 3750E, which reached end of software maintenance in January of this year, so that's the closest answer that can be given. Of course, if you have a hardware platform  (2970 or 3750, for example) with an earlier EOL date, then you may be even further past it. In any case, the date is in the past and not the future.

12.2(35)SE itself was last updated in 2007, so it's really old. Even if your switch is EOL, there are likely much newer IOS versions available for it.

Thanks Jody for your help.

Maybe I didn't use the correct term, should be EOS or retired IOS? I could find the info on later/other versions, but not on the two mentioned.

Ah... I see what you mean... and I stand corrected on the EOL announcements for IOS. Good to know.

I can't find a specific announcement for the EOL for 12.2(35)SE either, but if you go to the downloads section of the Cisco web site and go to the 12.2(35)SE release for the Catalyst 3750, you'll see that the last update for this version was 12.2(35)SE5 on 2007/07/30. Given that no releases have come out since then and its successor, 12.2(55)SE has a posted EOL announcement, I think it's fair to say that EOL for 12.2(35)SE was the release date of the last posted version. :)

12.4(13r)T10 sounds more like a bootstrap software version than an IOS version. Can you paste the output of the "show version" command that you're getting this from?

Thanks. I am more concerned about 12.2(35)SE as we have many 3750 running this release. I checked the retired table, and it indicated that 12.2(35)SE5 retired on Nov. 1, 2011. Does that mean EOSale or EOSM as it also indicated it might still be supported. Can anyone who knows help please? Thanks.

The best thing to do in order to get a specific EOS date is call TAC and ask them for that information.

Personally, I think you can be absolutely certain that if 12.2(55)SE is EOS, any previous minor release of 12.2SE is too.

Thanks Jody!
