3750X Stable IOS version

cco_heerema
Level 1
Level 1

Currently running all my 3750X's on Ios 15.0.2 SE2, all switches are in a minimum of a 2 member stack and a maximum of 6 members.

We are running in all sorts of issues lately.

High CPU due to the Auth Manager.

Not being able to use port security (will result in unstable switch).

Not being able to login with SSH.

So after a quick research I only found Early Deployment Ios versions in the 15 branch, can someone explain where the stable (golden medal) versions have gone ?

Just to be short, we need a stable "less evil" version of IOS IPbaseK9 which one do I choose ?

There has been many discussions on this subject, since IOS 15 seems to be very buggy so far.

Usually, the recommendation on the fourm is to tun 12.2(55)SE7 with proper license until 15 becomes more stable.

Most stable IOS is 12.2(55)SE8.  Second place goes to 15.0(2)SE4.

The worst one currently out for download is 15.2(1)E1.

Thank you all !

I am quite surprised that we still need to rely on the old 12.2 train and there is no real stable version in the 15 train.

Call me oldfashioned but I long for the days companies realy tested their software before publishing.

But if I hear you all well we need to downgrade the complete network back to 12.2(55)SE8
