description:
- Specifies which command will be used to get the current configuration.
By default the 'show running-config' command will be used, this command
masks some passwords. For example ike passwords for VPN. If you need to
match against masked passwords use 'more system:running-config'.
Note that the 'more system:running-config' only works in the system
context if you are running the ASA in multiple context mode.
