It's Christmas eve and Avaya ERS 3500's owners get the best gift of all. New switch code! Yay! Release v5.3.1 should be available from the Avaya web shortly. It adds Fabric Attach tech to the 3500's. Just like the 4000's and 5600's. Looks like some EAP changes and adds support for a few more optics modules. There are five fixes in this update. I usually like to see more than that, but it looks like this update was all about the Fabric Attach. As always, read your release notes.
