Maximum AnyConnect version for ASA5520/9.1.7 Interim

[sg_informatik]

I try to figure out what the last usable AnyConnect Version on an ASA5520 with ASA 9.1.7 Interim release is. I looked up 9.1 release notes that specified some versions for features like TLS and others but no clear statement if there is a last version. The same occured to me on the AnyConnect release notes.

If anybody knows some better resource to check or teaches me to better read the release notes I'd be very happy.

It looks like for 9.1 you can use anyconnect 4.x .

I was in that document before but I looked in the wrong spot.

Thanks for your help!

That's correct @Bogdan Nita

The legacy end of sales 5500 series (5510, 5520, 5540 and 5550) can run the newest AnyConnect 4.x.

However since they are limited to ASA software 9.1.7.x, they will not support some of the more advanced features like TLS 1.2 and NGE (Next Generation Encryption).
