3750 - 12.2(25) or 12.2(35)

Unanswered Question
Feb 15th, 2007

I've noticed that IOS version 12.2(35) has been poping on and off the early release list for the 3750. Does anyone know what the major differences between 12.2(25)SEB4 and 12.2(35)SE2?? Why would I choose one over the other?

I have this problem too.

good luck with that..

that utility is so messed up..

it doesn't even show me 12.2.35 se2

I even opened a tac call with a screen shot of the 3550 drill down showing me 2960 code and the tac engineer was going.. " I don't see the problem"

I gave up on tac, the guy was absolutely clueless... if someone from Cisco actually wants to see the problem, its already attached here somewhere, just search my name..

meanwhile back at the farm, I put 12.2.35 se on the switches and it seems to be running fine so far.

Sunbeam,

Are you having nightmares about Cisco's Feature Navigator? :-) Relax, the above reference is to the release notes.

Hi

Hi

I would suggest you to go in for 12.2(25) SEE2

as it has been there for good amount of time and its a stable image where as 12.2(35)SE2 has just released couple of days back so it will not be an ideal image to go in for.

I should have mentioned that I'm running IPBASE code and the purpose of this exercise is to upgrade code to conform with the DST changes happening on March 7th 2007. Does that change anyone's responses?
