Hi Jiri,
I tried the WiSM template and was able to retrieve the configuration using TFTP and SSH for the login. I am not successful with the ASA, though, and I'm using NCM 7.2.2 and ASA 8.4. If there's any way to improve on the device template, I'm happy to help out.
So far, I've just configured SSH as the script and login protocol and TFTP for the retrieval of the configuration and upped the timeout to 300seconds.
Thanks,
Matthew
