Having a minor issue with my switches and with Cisco Network Assistant at the moment. If I try to upgrade most of my 2960s, it fails almost immediately: Uploading the image; this might take a few minutes/seconds... Failed to execute the command archive download-sw /overwrite /http iosFile Software upgrade failed. Most of them were on 12.2(52)SE and trying to upgrade to 12.2(58)SE1 - all using LAN-BASE-CRYPTO. I suspect the crypto part is to blame as I was able to upgrade one switch via CNA that was running an earlier firmware which was just LAN-BASE. Same occurred while trying to upgrade switches to 12.2(55). I have been able to upgrade them to (58) by having the image on a TFTP server, both from the command line and from within CNA, using the remote TFTP option. Is this something your guys know anything about? Is there some crypto setup that I've missed?
