In previous version for CM, it's very easy to upgrade C-LAN firmware. But I met a problem in CM3.1.1. The document said I sould enable filexfer (security set to y), and use sftp command in DOS to connect C-LAN, but there's no such command. If I use the tradition way (security set to n), and ftp to C-LAN, it's ok, but I can not execute change firmware download in ASA, it prompt this kind of circuit can not be upgraded.
What's the wrong with it? Why there's no sftp command in DOS while the document said I should use that?
Thanks a lot!
