Downgrading to ver 22.214.171.124 will not help as I just attempted this on my SGE switch in my lab and got the same result as you. I can't explain why the GUI is not allow this to be changed lower than 3500 so I've sent this up to the Product team to review. I or someone else will post in here once we have an answer for you.
My appologies for the lack of reply here. I checked with the PM for the product and they asked me if there is a case open with the Small Business Support Center (SBSC) on this issue. Have you had a case open on this yet? If not can I ask you to log a case and then respond back to this postig with the case number please? It seems this is a bug so the product team will need to process the fix for this via the standard problem identification/case reporting process.
UPDATE...turns out that there is a bug fix already filed for this. Will be addressed in the next maintenance release of the Firmware (not yet sceduled), so no need to open a case with the SBSC on this one. Stay tuned...
