Hello,

Does anyone know if the ExtremeXOS 15.1.0.20 image is available anywhere on the download site? It appears the earliest available 15.x version is 15.1.1.6, but I was interested in the earlier version to debug a problem.

If no link is available, but I had access to a machine (Summit X440-24T) with the XOS version of interest, is it possible to extract the XOS image from the primary/secondary partition from the machine and use that?

Thanks in advance!

Hi Pat, welcome to The Hub!
EXOS v15.1.0.20 is a pre-release version, likely installed on your X440 at the factory.  It is not advisable to use this version in production because it is not fully tested.  Does the CLI prompt show "software upgrade required?"

Regarding the ability to transfer the software from another switch, this isn't possible.

Ah, ok. Thanks for the explanation!

Nevertheless, any way to obtain that or any other pre-release versions?

Thanks again!

You're welcome!
Unfortunately there is no way to provide them.  Can I ask what type of debugging you're trying to do that isn't applicable to a newer version?

We were looking at an issue involving dropped packets and CRC RX errors in the newer versions, which were not as prevalent on the pre-release version (i.e. only a few dropped packets, no CRC RX errors).

We're upgrading a couple of our X440 stacks to version to 16.1.3 just to have a couple up-to-date.

But before I go any further, should I create a new post for dropped packet / CRC RX error discussion? It doesn't seem relevant to this thread anymore.

Thanks again!

Sure, a new thread would be best as long as it pertains to a regular release version of EXOS :)
As an aside, and if you weren't already planning on it, be sure to load the latest patch of 16.1.3... v16.1.3.6-patch1-9.
