When a gateway powers up, SLS is disabled by default. However, if the gateway resets because of a CLI command, a software timeout, and so on, and the copy running-config startup-config command has not been issued prior to the reset, any administrative changes made are lost. This command is equivalent to save translation in Communication Manager.
Note:
Station passwords are stored in a special area of NVRAM to prevent them from being uploaded or downloaded through non-secure protocols.
