Code recommendations for X450G2

Code recommendations for X450G2

I am looking for a conservative code upgrade recommendation.

We have just under 100 X450G2 stacks deployed on a customers network. Per the software release recommendations page (Updated in March) we are running 21.1.3.7-patch1-4.

We have experiences a know bug on this code twice now. When replacing a failed master the ssh key gets corrupted causing the replacement switch to fail repeatedly.

The tac engineer I was working with recommended 22.3.1.4, but that seems like a step. It is a different major release and does not even have any patches yet. I cannot find the CR he reference but here are the log messages.

We do not want the customer to have to deal with the ssh key bug but we also don't want to open ourselves up to potential new issues by moving to to new of a code version.

Thanks for your thoughts,

George,

I am aware of the Matrix that is what led me to the bugged code in the first place. We should probably update that more often than every 7 months.

Hello David,

The easiest way around this issue it to re-create the SSH key on the stack. Here is an article that explains this a little better and has the CR:

Yes, I will check the release notes for the latest version of 22.2.x and see how that looks.

Solution 2 did not work for us the first time we encountered this. The second time, i went strait to the nuclear option.

Thanks for your input. I will check the release notes and post if i have any concerns.
